Internet Enhanced Service

This chapter provides information about Internet Enhanced Service (IES), used to provide IP routing services; that is, direct forwarding of IP traffic between CE devices, and also to facilitate the transport of in-band management datagrams of the 7705 SAR over ATM links.

Internet Enhanced Services can coexist with IES management SAP services on the same 7705 SAR node. IP over ATM is used exclusively for in-band management of the 7705 SAR. Up to two IPoATM SAPs can be bound to IES along with many other SAPs with other (non-ATM) supported SAP encapsulation types. Traffic from IPoATM SAPs is extracted to the CSM for further processing. Traffic received from other IES SAPs is forwarded as per the forwarding table (FIB).

Topics in this chapter include:

IES for In-band Management

Topics in this section include:

In the HSDPA offload application (see HSDPA Offload), the main uplink out of a typical cell site is over the ATM network using leased lines. Mission-critical traffic such as voice, signaling, and synchronization traffic is carried over the ATM network.

Internet Enhanced Service (IES) provides a reliable means of diverting the node management IP packets from the DSL IP network to the more reliable Layer 2 ATM network. To do this, IES provides an IP address and interworking function between the Layer 3 IP network and the Layer 2 ATM network. Without this capability, the in-band IP management traffic for the 7705 SAR could only be connected to an IP network.

IES can be used for in-band management of the 7705 SAR over the ATM network. IP over an ATM SAP bound to IES is for in-band management purposes only, and IP traffic from the ATM SAP is only extracted to the CSM; it is not forwarded.

IES management service is supported on the following cards for the 7705 SAR-8 Shelf V2 and 7705 SAR-18:

16-port T1/E1 ASAP Adapter card
32-port T1/E1 ASAP Adapter card

IES management service is also supported on the T1/E1 ports on the following:

7705 SAR-M
7705 SAR-A
7705 SAR-X
4-port T1/E1 and RS-232 Combination module

The service can be created on an ATM port or on an IMA group.

In the 7705 SAR, all traffic received over IES management SAPs is extracted directly to the control plane (CSM) in the same way as management traffic received over the CSM console port or Ethernet management port, or management traffic destined for the 7705 SAR over an Ethernet or MLPPP encapsulated network port. With IES management, the traffic transported is always IP packets. At the termination point of the ATM link, the IP packets are extracted to the CSM for further processing.

Setting Up Connections Between the NSP NFM-P and the 7705 SAR

IP over ATM is used for in-band management of the 7705 SAR. This requires the use of IP addresses so that the packets can be routed through the network using a routing table to indicate the next hop. Because Apipe interfaces (SAPs) do not have IP addresses, Apipes cannot be used to carry the management traffic.

With IES, the ATM SAP can be used for the forwarding of management IP packets. To set up a connection, IES is enabled on an interface on the 7705 SAR and the IP address for the interface is defined. A PVCC connection is then set up between the 7705 SAR and the remote router (SR) attached to the network manager (NSP NFM-P).

The IP datagrams are encapsulated into AAL5 for transport over the ATM network.

At the remote SR end, the SAP is bound to a VPRN instance to ensure that LDP signaling to the system IP address of the 7705 SAR flows through the IP/GRE link and not over the ATM link. Within the VPRN, an IP address is assigned at the termination SAP. The IP datagram is extracted from the ATM cell at this termination point and is routed to the NSP NFM-P.

Alternatively, manually configured connections can be used instead of signaled pseudowires.

Note: The remote IP address must be manually configured and a static route must be set up between the two connections. This configuration is beyond the scope of this document; see the 7705 SAR Router Configuration Guide for information.

For redundancy, it is recommended that two VCs be configured per ATM port or IMA group. This requires the configuration of two static routes. ECMP must be enabled to allow duplicate routes in the routing table, and BFD can be enabled to trigger a faster handoff to the other route in case of route failure.

Encapsulation

To run IP traffic over ATM links, the system uses routed VC-mux encapsulation as specified in RFC 2684, Multiprotocol Encapsulation over ATM Adaptation Layer 5. Because the only supported Layer 3 protocol over the management VC is IP, the VC mux encapsulation method is implemented to reduce complexity and overhead; likewise, routing mode is preferred over bridged mode.

The maximum MTU size supported is 2048 bytes.

Layer 2 and Layer 3 Traffic Management

ATM traffic descriptors can be applied at the ingress (policing) and egress (shaping and service category scheduling and prioritization) of the IES SAP in order to provide traffic management functions at Layer 2.

Management IP traffic that is destined for the CSM is classified at Layer 3 and is forwarded into the fabric from one of three of the adapter card control queues:

high priority
low priority
FTP priority

The high-priority and low-priority queues are limited to 1 Mb/s and the FTP queue is rate-limited to 3 Mb/s ingress to the fabric toward the control plane.

Note: Proper configuration of the traffic descriptor profiles is essential for proper operation of the IES SAP. If no profile is assigned, the default UBR service category is assumed. All IES 7705 SAR traffic is scheduled; no shaping is supported in this mode. To ensure that IP traffic transported over the IES SAP is prioritized fairly, ATM layer traffic descriptors should be assigned. See IES Management SAP Commands in the IES Command Reference section for information.

Troubleshooting and Fault Detection Services

The IES in-band management service supports ATM OAM F4 (VP level) and F5 (VC level) cell generation and termination. For more information about OAM, see the 7705 SAR OAM and Diagnostics Guide, ‟OAM and SAA”.

Bidirectional forwarding detection (BFD) can also be configured on the IES interface. BFD is a simple protocol for detecting failures in a network. BFD uses a ‟hello” mechanism that sends control messages periodically to the far end and receives periodic control messages from the far end. BFD is implemented for IGP and BGP protocols, including static routes, in asynchronous mode only, meaning that neither end responds to control messages; rather, the messages are sent in the time period configured at each end.

To support redundancy, ECMP must be enabled to allow duplicate routes in the routing table, and BFD must be enabled to trigger the handoff to the other route in case of failure.

Because of the lightweight nature of BFD, it can detect failures faster than other detection protocols, making it ideal for use in applications such as mobile transport.

If the configured number of consecutive missed BFD messages is reached, the route to the peer is declared not active.

Note: Layer 2 AIS/RDI cells that are received on the IES SAP disable the IP interface. Link failures detected by BFD also disable the IP interface.

IP ECMP Load Balancing

IP ECMP allows the configuration of load balancing across all IP interfaces at the system level or interface level on the network side. Layer 4 port attributes and the TEID attribute in the hashing algorithm can be configured with the l4-load-balancing and teid-load-balancing commands in the config>service>ies> interface context. Configuration of the l4-load-balancing command at the interface level overrides the system-level settings for the specific interface. The teid-load-balancing command can only be configured at the interface level.

The system IP address can be included in or excluded from the hashing algorithm with the system-level system-ip-load-balancing command.

For more information about IP ECMP, see the 7705 SAR Router Configuration Guide, ‟Static Routes, Dynamic Routes, and ECMP”.

IES for Customer Traffic

Topics in this section include:

IES provides IP connectivity between customer access points. From the customer’s perspective, IES provides a direct IP connection and can be used for Internet connectivity, as shown in IES for Customer Access to the Internet. The customer is assigned an IP interface and a SAP is associated with the IP interface to designate a customer access point to the service—one SAP per interface. SAPs can be MC-MLPPP, PPP/MLPPP, LAG, or null/dot1q/qinq Ethernet. SDPs are not required, because traffic is routed instead of being encapsulated in a tunnel.

any Ethernet port of the 7705 SAR-X

For more information about IPv6 addressing, see the 7705 SAR Router Configuration Guide, ‟Internet Protocol Versions”.

More than one Internet Enhanced Service can be created for a single customer ID, and more than one IP interface can be created within a single IES. All IP interfaces created within an IES belong to the same customer.

The service provider applies billing, ingress/egress shaping and policing to the customer.

Note:

Internet Enhanced Services require that the fabric mode be set to aggregate mode instead of per-destination mode. IES is only supported with aggregate-mode fabric profiles. If the fabric mode is set to per-destination mode, creation of the Internet Enhanced Service is blocked through the CLI. The fabric mode must be changed to aggregate mode before IES can be configured. As well, if IES is configured, alteration of the fabric mode is blocked.
For information about configuring fabric mode, see the 7705 SAR Quality of Service Guide, ‟Configurable Ingress Shaping to Fabric (Access and Network)”.

DHCP Relay and DHCPv6 Relay

The 7705 SAR provides DHCP/BOOTP Relay agent services and DHCPv6 Relay agent services for DHCP clients. DHCP is used for IPv4 network addresses and DHCPv6 is used for IPv6 network addresses. Both DHCP and DHCPv6 are known as stateful protocols because they use dedicated servers to maintain parameter information.

Unless stated otherwise, DHCP is equivalent to ‟DHCP for IPv4”, or DHCPv4.

In the stateful autoconfiguration model, hosts obtain interface addresses and/or configuration information and parameters from a server. The server maintains a database that keeps track of which addresses have been assigned to which hosts.

The 7705 SAR supports DHCP Relay on access IP interfaces associated with IES and VPRN and on network interfaces. Each DHCP instance supports up to eight DHCP servers.

The 7705 SAR supports DHCPv6 Relay on access IP interfaces associated with IES and VPRN. Each DHCPv6 instance supports up to eight DHCPv6 servers.

Note:

The 7705 SAR acts as a Relay agent for DHCP and DHCPv6 requests and responses, and can also be configured to function as a DHCP or DHCPv6 server. DHCPv6 functionality is only supported on network interfaces and on access IP interfaces associated with VPRN.
When used as a CPE, the 7705 SAR can act as a DHCP client to learn the IP address of the network interface. Dynamic IP address allocation is supported on both network and system interfaces.
For more information about DHCP and DHCPv6, see the 7705 SAR Router Configuration Guide, ‟DHCP and DHCPv6”.

DHCP Relay

The 7705 SAR provides DHCP/BOOTP Relay agent services for DHCP clients. DHCP is a configuration protocol used to communicate network information and configuration parameters from a DHCP server to a DHCP-aware client. DHCP is based on the BOOTP protocol, with additional configuration options and the added capability of allocating dynamic network addresses. DHCP-capable devices are also capable of handling BOOTP messages.

A DHCP client is an IP-capable device (typically a computer or base station) that uses DHCP to obtain configuration parameters such as a network address. A DHCP server is an Internet host or router that returns configuration parameters to DHCP clients. A DHCP/BOOTP Relay agent is a host or router that passes DHCP messages between clients and servers.

Home computers in a residential high-speed Internet application typically use the DHCP protocol to have their IP address assigned by their Internet service provider.

The DHCP protocol requires the client to transmit a request packet with a destination broadcast address of 255.255.255.255 that is processed by the DHCP server. Because IP routers do not forward broadcast packets, this would suggest that the DHCP client and server must reside on the same network segment. However, for various reasons, it is sometimes impractical to have the server and client reside in the same IP network. When the 7705 SAR is acting as a DHCP Relay agent, it processes these DHCP broadcast packets and relays them to a preconfigured DHCP server. Therefore, DHCP clients and servers do not need to reside on the same network segment.

DHCP OFFER messages are not dropped if they contain a yiaddr that does not match the local configured subnets on the DHCP relay interface. This applies only to regular IES and VPRN interfaces with no lease-populate configured on the DHCP relay interface.

DHCP Options

DHCP options are codes that the 7705 SAR inserts in packets being forwarded from a DHCP client to a DHCP server. Some options have more information stored in suboptions.

The 7705 SAR supports the Relay Agent Information Option 82 as specified in RFC 3046. The following suboptions are supported:

circuit ID
remote ID
vendor-specific options

DHCPv6 Relay

DHCPv6 Relay operation is similar to DHCP in that servers send configuration parameters such as IPv6 network addresses to IPv6 nodes, but DHCPv6 Relay is not based on the DHCP or BOOTP protocol. DHCPv6 can be used instead of stateless autoconfiguration (see the 7705 SAR Router Configuration Guide, ‟Neighbor Discovery”) or in conjunction with it.

DHCPv6 is also oriented around IPv6 methods of addressing, especially the use of reserved, link-local scoped multicast addresses. DHCPv6 clients transmit messages to these reserved addresses, allowing messages to be sent without the client knowing the address of any DHCP server. This transmission allows efficient communication even before a client has been assigned an IP address. When a client has an address and knows the identity of a server, it can communicate with the server directly using unicast addressing.

The DHCPv6 protocol requires the client to transmit a request packet with a destination multicast address of ff02::1:2 (all DHCP servers and relay agents on the local network segment) that is processed by the DHCP server.

Similar to DHCP address allocation, if a client needs to obtain an IPv6 address and other configuration parameters, it sends a Solicit message to locate a DHCPv6 server, then requests an address assignment and other configuration information from the server. Any server that can meet the client’s requirements responds with an Advertise message. The client chooses one of the servers and sends a Request message, and the server sends back a Reply message with the confirmed IPv6 address and configuration information.

If the client already has an IPv6 address, either assigned manually or obtained in some other way, it only needs to obtain configuration information. In this case, exchanges are done using a two-message process. The client sends an Information Request message, requesting only configuration information. A DHCPv6 server that has configuration information for the client sends back a Reply message with the information.

The 7705 SAR supports the DHCPv6 Relay Agent option in the same way that it supports the DHCP Relay Agent option. This means that when the 7705 SAR is acting as a DHCPv6 Relay Agent, it relays messages between clients and servers that are not connected to the same link.

DHCPv6 Options

DHCPv6 options are codes that the 7705 SAR inserts in packets being forwarded from a DHCPv6 client to a DHCPv6 server. DHCPv6 supports interface ID and remote ID options as defined in RFC 3315, Dynamic Host Configuration Protocol for IPv6 (DHCPV6) and RFC 4649, DHCPv6 Relay Agent Remote-ID Option.

IPCP

Similar to DHCP over Ethernet interfaces, Internet Protocol Control Protocol (IPCP) extensions to push IP information over PPP/MLPPP IES SAPs are supported. Within this protocol, extensions can be configured to define the remote IP address and DNS IP address to be signaled via IPCP on the associated PPP interface. The IPCP-based IP and DNS assignment process is similar to DHCP behavior; IPCP-based IP/DNS assignment uses PPP/MLPPP IP layer protocol handshake procedures. PPP/MLPPP connected devices hooked up to IES can benefit from this feature for the assignment of IP and DNS to the associated interface.

IPSec Support

The 7705 SAR supports IPSec and IPSec tunnels, where IES or VPRN is used as a public (untrusted) network-facing service and VPRN is used as a private (trusted) network-facing service. IES interfaces support the provisioning of tunnel SAPs as part of IPSec provisioning. The sap-id for a public-side IPSec tunnel SAP is tunnel-1.public:tag.

For more information, see the IPSec chapter in this guide.

Security Zones and IES

The 7705 SAR supports a number of mechanisms for node security, including Access Control Lists (ACLs), Network Address Translation (NAT), and stateful, zone-based firewalls. For information about ACLs, NAT, and firewalls, see the 7705 SAR Router Configuration Guide, ‟Configuring Security Parameters”.

To enable NAT or firewall functionality for IES, security policy and profile parameters must be configured under the config>security context in the CLI, and a security zone must be configured under the config>service>ies>zone context.

A zone is created by adding at least one Layer 2 endpoint or Layer 3 interface to the zone configuration. Security Zone Interfaces and Endpoints for IES lists the supported interfaces and endpoints that can be added to zones under IES NAT or firewall.

Table 1. Security Zone Interfaces and Endpoints for IES
CLI Context	Interface/Endpoint Type	NAT	Firewall
IES	SAP	✓	✓
	Spoke-SDP termination	✓	✓
	IPSec public	✓
	Routed VPLS	✓	✓

Proxy ARP

Proxy ARP is supported on IES interfaces.

Proxy ARP is a technique by which a router on one network responds to ARP requests intended for another node that is physically located on another network. The router effectively pretends to be the destination node by sending an ARP response to the originating node that associates the router’s MAC address with the destination node’s IP address (acts as a proxy for the destination node). The router then takes responsibility for routing traffic to the real destination.

For more information about proxy ARP, see the 7705 SAR Router Configuration Guide, ‟Proxy ARP”.

Configurable ARP Retry Timer

A timer is available to configure a shorter retry interval when an ARP request fails. An ARP request may fail for a number of reasons, such as network connectivity issues. By default, the 7705 SAR waits 5000 ms before retrying an ARP request. The configurable retry timer makes it possible to shorten the retry interval to between 100 and 30 000 ms.

Note: The ARP retry default value of 5000 ms is intended to protect CPU cycles on the 7705 SAR, especially when it has a large number of interfaces. Configuring the ARP retry timer to a value shorter than the default should be done only on mission-critical links, such as uplinks or aggregate spoke SDPs transporting mobile traffic; otherwise, the retry interval should be left at the default value.

The configurable ARP retry timer is supported on VPRN and IES service interfaces, as well on the router interface.

Unnumbered Interfaces

Unnumbered interfaces are supported on IES and VPRN services for IPv4. Unnumbered interfaces are point-to-point interfaces that are not explicitly configured with a dedicated IP address and subnet; instead, they borrow (or link to) an IP address from another interface on the system (the system IP address, another loopback interface, or any other numbered interface) and use it as the source IP address for packets originating from the interface.

This feature is supported via both dynamic and static ARP for unnumbered interfaces to allow interworking with unnumbered interfaces that may not support dynamic ARP.

The use of unnumbered interfaces has no effect on IPv6 routes; however, the unnumbered command must only be used in cases where IPv4 is active (IPv4 only and mixed IPv4/IPv6 environments). When using an unnumbered interface for IPv4, the loopback address used for the unnumbered interface must have an IPv4 address. The interface type for the unnumbered interface is automatically point-to-point.

Troubleshooting and Fault Detection Services

Bidirectional forwarding detection (BFD) can be configured on the IES interface. BFD is a simple protocol for detecting failures in a network. BFD uses a ‟hello” mechanism that sends control messages periodically to the far end and expects to receive periodic control messages from the far end. On the 7705 SAR, BFD is implemented for IGP and BGP protocols, including static routes, in asynchronous mode only, meaning that neither end responds to control messages; rather, the messages are sent periodically from each end.

To support redundancy with fast switchover, BFD must be enabled to trigger the handoff to the other route in case of failure.

Because of the lightweight nature of BFD, it can detect failures faster than other detection protocols, making it ideal for use in applications such as mobile transport.

If BFD packets are not received in the configured amount of time, the associated route is declared ‟not active”, causing a reroute to an alternative path, if any.

Note: Link failures detected by BFD disable the IP interface.

The 7705 SAR also supports Internet Control Message Protocol (ICMP and ICMPv6). ICMP is a message control and error reporting protocol that also provides information relevant to IP packet processing. For more information about ICMP and ICMPv6, see the 7705 SAR Router Configuration Guide, ‟ICMP and ICMPv6”.

VRRP on IES Interfaces

VRRP can be implemented on IES service interfaces to participate as part of a virtual router instance. This implementation prevents a single point of failure by ensuring access to the gateway address, which is configured on all IES service interfaces in the VRRP. VRRPv3 can also be implemented on IES service interfaces, including r-VPLS interfaces for IES.

The 7705 SAR supports VRRPv3 for IPv4 and IPv6 as described in RFC 5798. Within a VRRP router, the virtual routers in each of the IPv4 and IPv6 address families are in separate domains and do not overlap.

Note:

VRRPv3 for IPv6 is not supported on a Layer 3 spoke SDP termination.
VRRP is not supported on an IPSec public interface.

For information about VRRP and VRRP IES service interface parameters, as well as the configuration parameters of VRRP policies, see the ‟VRRP” section in the 7705 SAR Router Configuration Guide. CLI command descriptions for VRRP policies are also specified in the 7705 SAR Router Configuration Guide.

For CLI command descriptions related to IES service interfaces, see IES Command Reference.

SAPs

Topics in this section include:

Encapsulations

The following SAP encapsulations are supported on the 7705 SAR Internet Enhanced Service:

Ethernet null
Ethernet dot1q
Ethernet qinq
PPP/MLPPP/MC-MLPPP

Routing Protocols

IES supports static routes on customer IP interfaces (that is, SAPs). These routes are redistributed into the global routing table of the 7705 SAR.

OSPFv2, RIP, and PIM routing protocols are supported on IES SAPs (that is, access IP interfaces). IES SAPs on V.35 ports on the 12-port Serial Data Interface card, version 3, support only OSPFv2 and static routing protocols.

The SAP for the IES IP interface is created at the IES service level, but the routing protocol for the IES IP interface is configured at the routing protocol level for the main router instance in the global context.

See the chapters on ‟OSPF” and ‟RIP” in the 7705 SAR Routing Protocols Guide for information about configuring these routing protocols.

IPv4 in IES supports PIM-SM and PIM-SSM. IPv6 in IES supports PIM-SSM. See the ‟IP Multicast” chapter in the 7705 SAR Routing Protocols Guide for information about configuring these routing protocols.

QoS Policies

When applied to an Internet Enhanced Service SAP, service ingress QoS policies only create the unicast queues defined in the policy.

Service egress QoS policies function in the same way as Ethernet and IP pseudowire services, where class-based queues are created based on the QoS policy. Multiple queues are supported. See the 7705 SAR Quality of Service Guide, ‟Creating a Service Egress QoS Policy”.

Both Layer 2 and Layer 3 match criteria can be used in the QoS policies for traffic classification in an IES.

QinQ (IES)

IES supports QinQ functionality. For details, see QinQ Support.

IP Filter Policies on an IES SAP

IPv4 filter policies can be applied to ingress IES management SAPs.

IPv4 and IPv6 filter policies can be applied to both ingress and egress IES SAPs (null, dot1q, or qinq interfaces).

Configuration and assignment of IP filter policies is similar for all services. See the 7705 SAR Router Configuration Guide, ‟Filter Policies”, for information about configuring IP filters.

Spoke SDP Termination to IES

This feature enables a customer to exchange traffic between a VLL or VPLS (Layer 2) service and an IES or VPRN (Layer 3) service. Customer premises traffic coming in from a VLL or VPLS service (SAP to spoke SDP) is forwarded over the IP/MPLS network to the IES or VPRN service, and vice versa. Network QoS policies can be applied to the spoke SDP to control traffic forwarding to the Layer 3 service.

In a Layer 3 spoke SDP termination to an IES or VPRN service, where the destination IP address resides within the IES or VPRN network, CE device-generated ARP frames must be processed by the Layer 3 interface. When an ARP frame is received over the spoke SDP at the Layer 3 interface endpoint, the 7705 SAR responds to the ARP frame with its own MAC address. When an ARP request is received from the routed network and the ARP entry for the CE device that is connected to the spoke SDP is not known, the 7705 SAR initiates an ARP frame to resolve the MAC address of the next hop or CE device.

SDP ID and VC Label Service Identifiers (Conceptual View of the Service) shows traffic terminating on a specific IES or VPRN service that is identified by the SDP ID and VC label present in the service packet.

Figure 2. SDP ID and VC Label Service Identifiers (Conceptual View of the Service)

IES Spoke SDP Termination shows a spoke SDP terminating directly into an IES. In this case, a spoke SDP could be tied to an Epipe or a hierarchical VPLS service. There is no configuration required on the PE connected to the CE.

Ethernet spoke SDP termination for IES is supported over the following network uplinks:

Ethernet network ports (null or dot1q encapsulation)
PPP/MLPPP network ports. For information about PPP/MLPPP ports, see the 7705 SAR Interface Configuration Guide, ‟Access, Network, and Hybrid Ports”
POS ports

Spoke SDP termination for IES supports the following:

Ethernet PW to VRF
interface shutdown based on PW standby signaling
spoke SDP ingress IP filtering with filter logging
label withdrawal for spoke SDPs terminated on IES
statistics collection
VCCV ping (type 2)

A spoke SDP on an IES interface can be connected to the following entities:

Epipe spoke SDP
Epipe spoke SDP redundancy with standby-signal-master enabled
IES interface
VPRN interface
VPLS spoke SDP
VPLS spoke SDP redundancy with suppress-standby-signaling disabled

Pseudowire-Based Backhaul (Spoke SDP Termination at 7750 SR) shows an example of backhauling from a specific site that uses PW and IES on the 7705 SAR. An individual PW is configured on a per-CE device or a per-service basis. For routing services, this PW can be terminated to an IES at the 7750 SR end. This scenario offers per-service OAM and redundancy capabilities. Because there is no local communication on the remote 7705 SAR, traffic between any two devices connected to the 7705 SAR must traverse through the 7750 SR at the MTSO/CO.

Figure 4. Pseudowire-Based Backhaul (Spoke SDP Termination at 7750 SR)

Bandwidth Optimization for Low-speed Links

The 7705 SAR can be used in deployments where the uplink bandwidth capacity and requirements are considerably less than if the router is used for fixed or mobile backhaul applications. For example, the 7705 SAR can be used to direct traffic from multiple individual homes for applications such as smart meter aggregation or relay connectivity. Connecting to end systems such as smart meters or relays requires uplink bandwidth capacity in terms of hundreds of kilobits per second, rather than hundreds of megabits per second.

One way to optimize operation in lower-bandwidth applications is to minimize head-of-line (HoL) blocking caused by large packets. HoL blocking occurs when transmission of a large non-mission-critical packet delays a mission-critical packet beyond acceptable limits. The propagation delay of large packets over a slow link is fairly significant. For example, the propagation delay when transmitting a 1500-byte packet over a 100 kb/s link is 120 ms. If a mission-critical packet is queued immediately after the first bit of a non-mission-critical 1500-byte packet begins transmission, the mission-critical packet must wait 120 ms before the uplink is available again.

To minimize HoL blocking, the 7705 SAR supports a lower MTU of 128 bytes (from the original 512-byte minimum) so that large IP packets are fragmented into 128-byte chunks. In the preceding example, transmitting a 128-byte packet over a 100 kb/s link only delays the next packet by 10.24 ms.

This lower MTU is supported on IES and VPRN interfaces (access interfaces) and on network interfaces. The IP MTU is derived from the port MTU, unless specifically configured with the ip-mtu command. This command is supported on access interfaces only.

The following must be considered when using a lower IP MTU:

applicability – the lower IP MTU is only applicable for IP forwarded traffic and cannot be applied to pseudowire or VPLS traffic
reassembly – the far-end/destination node must reassemble the packet before it can process the data, which may impact the performance of the end system and/or may require different hardware to perform the reassembly
extra overhead – each fragment must have an IPv4 header so that all fragments of the packet can be forwarded to the destination. Care must be taken to ensure that the extra IP overhead for each fragment does not offset the gain achieved by using the lower MTU. As an example, for a 128-byte packet, the IPv4 header, which is 20 bytes in length, constitutes approximately 15% of the total packet size.

Note:

Lower IP MTU applies to IPv4 applications only. As per RFC 2640, IPv6 interfaces or dual-stack interfaces should not be configured to a value lower than 1280 bytes.
Lower IP MTU is supported only on Ethernet encapsulated ports.
Most routing and signaling protocols, such as OSPF, IS-IS, and RSVP-TE, cannot be supported with port MTUs lower than 512 bytes because of the protocol layer requirements and restrictions.
Special care must be taken with routing protocols that use TCP, such as BGP and LDP. The minimum TCP MSS value supported on the 7705 SAR is 384 bytes; therefore, these protocols should only be enabled on links that can transport 384-byte IP packets without fragmentation. If there is a mismatch in TCP MSS in the network, this mismatch can potentially cause severe network performance issues because of the overhead caused by fragmentation and retransmissions, it can cause multi-vendor interoperability issues, and it can potentially cause the protocols to continuously flap.
Not all OAM diagnostics are supported with lower port MTUs. Detailed information is provided in OAM Diagnostics Restrictions with Lower IP MTU.

OAM Diagnostics Restrictions with Lower IP MTU

OAM tests require a minimum network port MTU in order to run; this value depends on the test. If the port MTU is set to a value lower than the minimum requirement, the test fails.

If the port MTU is set to a value that meets the minimum requirement, the packet size parameter can be configured for the test (for example, oam sdp-ping 1 size 102).

If the size parameter is not specified, the system builds the packet based on the default payload size. If the size parameter is configured and is greater than the default payload size, padding bytes are added to equal the configured value.

The packet size is dependent on the port MTU value; that is, if the minimum port MTU value is used, there are restrictions on the packet size. If the configured size is greater than the maximum value supported with the minimum port MTU, the test fails.

Port MTU Requirements for OAM Diagnostics (GRE Tunnels) and Port MTU Requirements for OAM Diagnostics (LDP Tunnels) list the minimum port MTU required for each OAM test and the maximum size of the OAM packet that can be configured when the minimum port MTU is used, based on SDP tunnel type.

Note: RSVP LSPs do not come up if the network port MTU value is lower than 302 bytes.

Hold Up and Hold Down Timers for IP Interfaces

The 7705 SAR allows timers to be configured on an IES or VPRN IPv4 or IPv6 interface or on the base router to keep the IP interface in an operationally up or down state for a specified time beyond when it should be declared operationally up or down. The timers are configured at the IES service level using the config>service>ies>interface>hold-time>up/down commands. An init-only option enables the down delay to be applied only when the IP interface is first configured or after a system reboot. See VPRN Services for information about how to configure the hold-time command on IES interfaces. See the 7705 SAR Router Configuration Guide for information about how to configure the hold-time command at the router level.

The configuration causes the system to delay sending notifications of any state change associated with the IP interface until the timer has expired.

Note: The up and down delay timers in the CLI are dynamic text fields; the fields are only displayed in the show router interface detail command output if they are configured. The field showing the time remaining is displayed only if the timer is actively counting down. If both up and down timers are configured, the field displayed depends on the current operational state of the interface. For example, if the interface is operationally down, the configured hold down time is displayed.

Configuring IES with CLI

This section provides the information required to configure IP routing services; that is, direct forwarding of IP traffic between CE devices, and to configure IES for in-band management of the 7705 SAR over ATM links.

Topics in this section include:

Common Configuration Tasks

The following list provides a brief overview of the tasks that must be performed to configure IES.

Associate the IES service with a customer ID.
Create an IP interface on the 7705 SAR.
Specify the IP address of the interface.
Define interface parameters.
Define SAP parameters.
For IES spoke SDP applications only — define spoke SDP parameters.
For IES applications only — configure VRRP (optional).
For IES management service only—manually configure the remote address of the far-end router to which the NSP NFM-P is connected (far-end router must be enabled for IES service).*
For IES management service only—create a static route to the remote router and to the NSP NFM-P.*
Enable the service.

Note: *Remote address and static route configuration is beyond the scope of this document. For information, see the 7705 SAR Router Configuration Guide.

Configuring IES Components

This section provides configuration examples for components of the IES service. Each component includes some or all of the following: introductory information, CLI syntax, a specific CLI example, and an example of the CLI display output.

Topics in this section include:

Creating an IES Service

Use the following CLI syntax to create an IES service.

CLI Syntax:

config>service# ies service-id [customer customer-id] [create] [vpn vpn-id]
    description description-string
    interface ip-int-name [create]
    no shutdown

Example:

A:ALU-41>config>service# ies 5 customer 1 create
A:ALU-41>config>service>ies# description ‟IES for in-band management”
A:ALU-41>config>service>ies# interface ‟ATMoIP Management” create
A:ALU-41>config>service>ies# no shutdown
A:ALU-41>config>service>ies#

The following example displays the IES service creation output.

A:ALU-41>config>service# info

           exit
           no shutdown
-------------------------------------

Configuring VRRP

Configuring VRRP policies and instances on service interfaces is optional. The basic owner and non-owner VRRP configurations on an IES interface must specify the backup ip-address parameter.

VRRP helps eliminate the single point of failure in a routed environment by using virtual router IP addresses shared between two or more routers connecting the common domain. VRRP provides dynamic failover of the forwarding responsibility to the backup router if the master becomes unavailable.

The VRRP implementation allows one master per IP subnet. All other VRRP instances in the same domain must be in backup mode.

For more information about VRRP CLI syntax and command descriptions for an IES service interface, see IES Command Reference. For overview information about VRRP and VRRP IES interface parameters, see the ‟VRRP” chapter in the 7705 SAR Router Configuration Guide.

The following displays an IES interface VRRP owner configuration:

Configuring a Security Zone Within IES

To configure NAT or firewall security, you must:

configure a NAT or firewall security profile and policy in the config>security context
- in the config>security>profile context, specify the timeouts for the TCP/UDP/ICMP protocols and configure logging and application assurance parameters. This step is optional. If you do not configure the profile, a default profile is assigned.
- in the config>security>policy context, configure a security policy, specify the match criteria and the action to be applied to a packet if a match is found.
configure a security zone and apply the policy ID to the zone, as shown in the CLI syntax below

CLI Syntax:

config>service
    ies service-id [customer customer-id] [create]
    abort
    begin
    commit
    zone zone-id [create]
        description description-string
        interface ip-int-name [create]
        name zone-name
        nat
            pool pool-id [create]
                description description-string
                direction {zone-outbound | zone-inbound | both}
                entry entry-id [create]
                    ip-address ip-address [to ip-address] interface ip-int-name
                    port port [to port] interface ip-int-name
                name pool-name
        policy policy-id | policy-name
        shutdown

The following example displays a NAT zone configuration output.

Configuring Serial Raw Socket Transport Within IES

Configure an IP transport subservice within an IES service in order to enable the transport of serial data using raw sockets.

CLI Syntax:

config>service
    ies service-id [customer customer-id] [create]
        ip-transport ipt-id [create]
            description description-string
            filter-unknown-host
            local-host ip-addr ip-addr port-num port-num] protocol {tcp|udp}
            remote-host host-id [ip-addr ip-addr] [port-num port-num] [create]
                description description-string
                name host-name
                exit
            fc fc-name profile {in |out}
            shutdown
            tcp
                inactivity-timeout number
                max-retries seconds
                retry-interval seconds
            exit
        exit
    exit
exit

The following example displays an IP transport subservice configuration output.

Service Management Tasks

This section discusses the following service management tasks:

Modifying IES Service Parameters

Existing IES service parameters can be modified, added, removed, enabled, or disabled.

To display a list of customer IDs, use the show>service>customer command.

Enter the parameters (such as description, interface information, or SAP information), and then enter the new information.

The following is an example of changing the IP MTU size.

Example:

A:ALU-41>config>service# ies 5
A:ALU-41>config>service>ies# interface ‟testname”
A:ALU-41>config>service>ies>if# ip-mtu 1517
A:ALU-41>config>service>ies>if# exit

Disabling an IES Service

An IES service can be shut down without deleting the service parameters.

Use the shutdown command to shut down an IES service.

CLI Syntax:

config>service# ies service-id
    shutdown

Example:

A:ALU-41>config>service# ies 5
A:ALU-41>config>service>ies# shutdown
A:ALU-41>config>service>ies# exit

Re-enabling an IES Service

Use the no shutdown command to re-enable a previously disabled IES service.

CLI Syntax:

config>service# ies service-id
    no shutdown

Example:

A:ALU-41>config>service# ies 5
A:ALU-41>config>service>ies# no shutdown
A:ALU-41>config>service>ies# exit

Deleting an IES Service

An IES service cannot be deleted until SAPs, spoke SDPs, and interfaces are shut down and deleted and the service is shut down on the service level.

Use the following CLI syntax to delete an IES service:

CLI Syntax:

config>service#
    ies service-id
        interface ip-int-name
            sap sap-id
                shutdown
                exit
            no sap sap-id
            spoke-sdp sdp-id:vc-id 
                shutdown
                exit
            no spoke-sdp sdp-id:vc-id 
        interface ip-int-name
            shutdown
            exit
        no interface ip-int-name
        shutdown
        exit
    no ies service-id

config>service>ies>ip-transport

Description

This command administratively disables an entity. The operational state of the entity is disabled as well as the operational state of any entities contained within. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. Many objects must be shut down before they may be deleted. Many entities must be explicitly enabled using the no shutdown command.

The no form of this command places the entity into an administratively enabled state.

The dhcp and dhcp6-relay commands do not apply to IES when used for in-band management.

Services are created in the administratively down (shutdown) state. When a no shutdown command is entered, the service becomes administratively up and tries to enter the operationally up state. Default administrative states for services and service entities are described in the following Special Cases.

Special Cases

IES

the default administrative status of an IES service is down. While the service is down, its associated interface is operationally down.

For example, if:

1) An IES service is operational and its associated interface is shut down

2) The IES service is administratively shut down and brought back up

3) The interface that is shut down remains in the administrative shutdown state

A service is regarded as operational provided that one IP interface is operational.

IES IP Interfaces: when the IP interface is shut down, it enters the administratively and operationally down states. For a SAP bound to the IP interface, no packets are transmitted out of the SAP and all packets received on the SAP are dropped and the packet discard counter is incremented.

IES IP transport subservice

when an IP transport subservice within an IES service is shut down, all TCP/UDP packets received from remote hosts are dropped and any serial data received from the serial port is dropped. Any TCP connections that were up are closed and no new TCP connection requests are accepted.

It is not possible to make configuration changes to an IP transport subservice without performing a shutdown first.

The operational state of an IP transport subservice is relative to the operational state of the serial port for which the IP transport subservice is defined. When a serial port is shut down, the IP transport subservice associated with the serial port becomes operationally down.

When the no shutdown command is executed for an IP transport subservice, it becomes operationally up, serial data from the serial port is encapsulated in TCP/UDP packets destined for remote hosts, and TCP/UDP packets can be received by the local host, where raw serial data is then sent out the serial port.

IES Global Configuration Commands

ies

Syntax

ies service-id [customer customer-id] [create] [vpn vpn-id]

no ies service-id

Context

config>service

Description

This command enables Internet Enhanced Service (IES). On the 7705 SAR, IES is used for direct IP connectivity between customer access points as well as in-band management of the 7705 SAR over ATM links.

The no form of this command deletes the IES service instance with the specified service-id.

The service cannot be deleted until all the IP interfaces defined within the service ID have been shut down and deleted.

Parameters

service-id

uniquely identifies a service in the service domain. This ID must be unique to this service and may not be used for any other service of any type. The service-id must be the same number or name used for every 7705 SAR on which this service is defined.

Values: 1 to 2147483647 or service-name

customer-id

specifies the customer ID number to be associated with the service. This parameter is required on service creation and is optional for service editing or deleting.

Values: 1 to 2147483647

vpn-id

specifies the VPN ID number, which allows you to identify virtual private networks (VPNs) by a VPN identification number. If this parameter is not specified, the VPN ID uses the service ID number. This parameter is not the same as the VRF ID used with VPRN services.

Values: 1 to 2147483647

service-name

Syntax

service-name service-name

no service-name

Context

config>service>ies

Description

This command configures a service name that can be used in other configuration commands and show commands that reference the service.

Parameters

service-name: up to 64 characters

IES Management Configuration Commands

IES Management Interface Commands

interface

Syntax

interface ip-int-name [create]

no interface ip-int-name

Context

config>service>ies

Description

This command creates a logical IP routing interface for an Internet Enhanced Service (IES). When created, attributes like an IP address and service access point (SAP) can be associated with the IP interface.

Interface names are case-sensitive and must be unique within the group of IP interfaces defined for config router interface and config service ies interface (that is, the network core router instance). Interface names cannot be in the dotted-decimal notation of an IP address. For example, the name ‟1.1.1.1” is not allowed, but ‟int-1.1.1.1” is allowed. Show commands for router interfaces use either interface names or the IP addresses. Use unique IP address values and IP address names to maintain clarity. It could be unclear to the user if the same IP address and IP address name values are used. Although not recommended, duplicate interface names can exist in different router instances.

When a new name is entered, a new logical router interface is created. When an existing interface name is entered, the user enters the router interface context for editing and configuration.

There are no default IP interface names defined within the system. All IES IP interfaces must be explicitly defined. Interfaces are created in an enabled state.

The no form of this command removes the IP interface and all the associated configurations. The interface must be administratively shut down before issuing the no interface command. The IP interface must be shut down before the SAP on that interface can be removed.

Default

no interface

Parameters

ip-int-name

the name of the IP interface. Interface names must be unique within the group of IP interfaces defined for the network core router instance. An interface name cannot be in the form of an IP address. If the string contains special characters (such as #, $, or spaces), the entire string must be enclosed within double quotes.

Values: 1 to 32 characters (must start with a letter)

If the ip-int-name already exists, the context is changed to maintain that IP interface. If the ip-int-name already exists as an IP interface defined within the config router command, an error will occur and the context will not be changed to that IP interface. If the ip-int-name does not exist, the interface is created and the context is changed to that interface for further command processing.

address

Syntax

address {ip-address/mask | ip-address netmask}

no address

Context

config>service>ies>interface

Description

This command assigns an IP address and IP subnet to an IES IP interface. Only one IP address can be associated with an IP interface.

An IP address must be assigned to each IP interface. An IP address and a mask combine to create a local IP prefix. The defined IP prefix must be unique within the context of the routing instance. The IP prefix cannot overlap with other existing IP prefixes defined as local subnets on other IP interfaces in the same routing context within the 7705 SAR.

The IP address for the interface can be entered in either CIDR (classless inter-domain routing) notation or traditional dotted-decimal notation. Show commands display CIDR notation and are stored in configuration files.

By default, no IP address or subnet association exists on an IP interface until it is explicitly created.

The no form of the command removes the IP address assignment from the IP interface. The no form of this command can only be performed when the IP interface is administratively shut down. Shutting down the IP interface brings the interface operationally down.

Default

no address

Parameters

ip-address

the IP address of the IP interface. The ip-address portion of the address command specifies the IP host address that will be used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.

Values: 1.0.0.0 to 223.255.255.255

/: the forward slash is a parameter delimiter that separates the ip-address portion of the IP address from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-address, the ‟/”, and the mask parameter. If a forward slash does not immediately follow the ip-address, a dotted-decimal mask must follow the prefix.

mask

the subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-address from the maskparameter. The mask parameter indicates the number of bits used for the network portion of the IP address; the remainder of the IP address determines the host portion of the IP address.

Values: 1 to 32 (mask length of 32 is reserved for system IP addresses)

netmask

the subnet mask in dotted-decimal notation

Values: 0.0.0.0 to 255.255.255.255 (network bits all 1 and host bits all 0)

bfd

Syntax

bfd transmit-interval [receive receive-interval] [multiplier multiplier] [type np]

no bfd

Context

config>service>ies>interface

config>service>ies>if>ipv6

Description

This command configures the time interval in which BFD control messages are transmitted and received on the interface. The multiplier parameter specifies the number of consecutive BFD messages that must be missed by the peer node before the BFD session closes and the upper layer protocols (OSPF, IS-IS, BGP, PIM) are notified of the fault.

Default

no bfd

Parameters

transmit-interval

the number of milliseconds between consecutive BFD sent messages

Values: 10 to 100000

Default: 100

receive-interval

the number of milliseconds between consecutive BFD received messages

Values: 10 to 100000

Default: 100

multiplier

the number of consecutive BFD messages that must be missed before the interface is brought down

Values: 3 to 20

Default: 3

type np: controls the value range of the transmit-interval and receive-interval parameters. If the type np option is not specified, the range of the transmit-interval and receive-interval parameter values is from 100 ms to 100000 ms. If the type np option is specified, the range of the transmit-interval and receive-interval parameter values is from 10 ms to 1000 ms, with the restriction that the maximum receiving detection time for the missing BFD packets must be less than or equal to 3000 ms. The maximum receiving detection time is the receive-interval parameter multiplied by the multiplier parameter.

Note: The BFD session must be disabled before the type np parameter can be changed.

cflowd-parameters

Syntax

cflowd-parameters

Context

config>service>ies>interface

Description

This command enables the context to configure cflowd parameters for the specified IP interface.

Cflowd is used for network planning and traffic engineering, capacity planning, security, application and user profiling, performance monitoring, usage-based billing, and SLA measurement.

Default

n/a

sampling

Syntax

sampling {unicast | multicast} type {interface} [direction {ingress-only | egress-only | both}]

no sampling {unicast | multicast}

Context

config>service>ies>if>cflowd-parameters

Description

This command configures the cflowd sampling behavior to collect traffic flow samples through a router for analysis.

This command can be used to configure the sampling parameters for unicast and multicast traffic separately.

If cflowd sampling is enabled with no direction parameter specified, ingress-only sampling is enabled by default.

The no form of the command disables the configured type of traffic sampling on the interface.

Default

no sampling unicast no sampling multicast

Parameters

unicast: cflowd samples unicast traffic on the interface

multicast: cflowd samples multicast traffic on the interface

interface: specifies that all traffic entering or exiting the interface is subject to sampling. Interface is the only sampling type supported on the 7705 SAR and must be specified with this command.

direction: specifies the direction in which to collect traffic flow samples: ingress-only, egress-only, or both

ip-mtu

Syntax

ip-mtu octets

no ip-mtu

Context

config>service>ies>interface

Description

The no form of the command returns the default value.

Parameters

octets

the MTU for the interface

Values: 128 to 9732

IES Management SAP Commands

sap

Syntax

sap sap-id [create]

no sap sap-id

Context

config>service>ies>interface

Description

This command creates a SAP within an IES service. Each SAP must be unique.

All SAPs must be explicitly created with the create keyword. If no SAPs are created within a service or on an IP interface, a SAP will not exist on that object.

Enter an existing SAP without the create keyword to edit SAP parameters.

A SAP can only be associated with a single service. The SAP is owned by the service in which it was created. An IES SAP can only be defined on an ATM port or IMA group that has been configured as an access port in the config>port port-id context using the mode access command. Fractional TDM ports are always access ports. See the 7705 SAR Interface Configuration Guide for information about access ports.

If a port is shut down, all SAPs on that port become operationally down. When a service is shut down, SAPs for the service are not displayed as operationally down although all traffic traversing the service will be discarded. The operational state of a SAP is relative to the operational state of the port on which the SAP is defined.

The no form of this command deletes the SAP with the specified port. When a SAP is deleted, all configuration parameters for the SAP will also be deleted.

Default

no sap

Parameters

sap-id: specifies the physical port identifier portion of the SAP definition. See SAP ID Configurations for a full list of SAP IDs.

create: keyword used to create a SAP instance. The create keyword requirement can be enabled/disabled in the environment>create context.

ingress

Syntax

ingress

Context

config>service>ies>if>sap

Description

This command enables access to the context to associate ingress filter policies with the SAP.

If an ingress filter is not defined, no filtering is performed.

filter ip

Syntax

filter ip ip-filter-id

no filter

no filter [ip ip-filter-id]

Context

config>service>ies>if>sap>ingress

Description

This command associates an IP filter policy with an ingress SAP. Filter policies control the forwarding and dropping of packets based on the IP match criteria. Only one filter ID can be specified.

The filter policy must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message is returned. Filters applied to the ingress SAP apply to all IP packets on the SAP.

The no form of this command removes any configured filter ID association with the SAP.

Default

no filter

Parameters

ip-filter-id

specifies the IP filter policy. The filter ID or filter name must already exist within the created IP filters.

Values: 1 to 65535 or filter-name (up to 64 characters)

Note: For information about configuring IP filter IDs, see the 7705 SAR Router Configuration Guide, ‟Filter Policies”.

atm

Syntax

atm

Context

config>service>ies>if>sap

Description

This command enables access to the context to configure ATM-related attributes. This command can only be used when a specific context (for example, a channel or SAP) supports ATM functionality such as:

configuring ATM port or ATM port-related functionality on T1/E1 ASAP adapter cards on a 7705 SAR-8 Shelf V2 or 7705 SAR-18 or on T1/E1 ports on a 7705 SAR-M
configuring ATM-related configuration for ATM-based SAPs that exist on T1/E1 ASAP adapter cards on a 7705 SAR-8 Shelf V2 or 7705 SAR-18 or on T1/E1 ports on a 7705 SAR-M

If ATM functionality is not supported for a specific context, the command returns an error.

encapsulation

Syntax

encapsulation atm-encap-type

Context

config>service>ies>if>sap>atm

Description

This command configures an ATM VC SAP for encapsulation in accordance with RFC 2684, Multiprotocol Encapsulation over ATM Adaptation Layer 5. This command is only supported in the IP over ATM management context.

The only supported encapsulation type is aal5mux-ip.

Ingress traffic that does not match the configured encapsulation is dropped.

Default

aal5mux-ip

Parameters

atm-encap-type: aal5mux-ip (routed IP encapsulation for a VC multiplexed circuit as defined in RFC 2684)

egress

Syntax

egress

Context

config>service>ies>if>sap>atm

Description

This command provides access to the context to configure egress ATM traffic policies for the SAP.

ingress

Syntax

traffic-desc

Syntax

traffic-desc traffic-desc-profile-id

no traffic-desc

Context

config>service>ies>if>sap>atm>egress

config>service>ies>if>sap>atm>ingress

Description

This command assigns an ATM traffic descriptor profile to an egress or ingress SAP.

When configured under the ingress context, the specified traffic descriptor profile defines the traffic contract in the forward direction.

When configured under the egress context, the specified traffic descriptor profile defines the traffic contract in the backward direction.

The no form of the command reverts to the default traffic descriptor profile.

Default

The default traffic descriptor (trafficDescProfileId. = 1) is associated with newly created ATM VC SAPs.

Parameters

traffic-desc-profile-id

specifies a defined traffic descriptor profile (for information about defining traffic descriptor profiles, see the 7705 SAR Quality of Service Guide)

Values: 1 to 1000

oam

Syntax

oam

Context

config>service>ies>if>sap>atm

Description

This command enables the context to configure OAM functionality for an IES SAP.

The T1/E1 ASAP Adapter cards support F4 and F5 end-to-end OAM functionality (AIS, RDI, Loopback).

alarm-cells

Syntax

[no] alarm-cells

Context

config>service>ies>if>sap>atm>oam

Description

This command configures AIS/RDI fault management on a PVCC. Fault management allows PVCC terminations to monitor and report the status of their connection by propagating fault information through the network and by driving the PVCC operational status.

Layer 2 OAM AIS/RDI cells that are received on the IES SAP cause the IP interface to be disabled.

The no command disables alarm-cells functionality for the SAP. When alarm-cells functionality is disabled, OAM cells are not generated as result of the SAP going into the operationally down state.

Default

enabled

IES Service Configuration Commands

IES Service Interface Commands

interface

Syntax

[no] interface ip-int-name [create]

Context

config>service>ies

Description

This command creates a logical IP routing interface for Internet Enhanced Service (IES). When created, attributes like an IP address and service access point (SAP) can be associated with the IP interface.

The interface command, under the context of services, creates and maintains IP routing interfaces within IES service IDs. The interface command can be executed in the context of an IES service ID. The IP interface created is associated with the service core network routing instance and the default routing table. Two SAPs can be assigned to a single group interface.

Interface names are case-sensitive and must be unique within the group of IP interfaces defined for config router interface and config service ies interface (that is, the network core router instance). Interface names cannot be in the dotted-decimal format of an IP address. For example, the name ‟1.1.1.1” is not allowed, but ‟int-1.1.1.1” is allowed. Show commands for router interfaces use either interface names or the IP addresses. Use unique IP address values and IP address names to maintain clarity. It could be unclear to the user if the same IP address and IP address name values are used. Although not recommended, duplicate interface names can exist in different router instances.

When a new name is entered, a new logical router interface is created. When an existing interface name is entered, the user enters the router interface context for editing and configuration.

There are no default IP interface names defined within the system. All IES IP interfaces must be explicitly defined. Interfaces are created in an enabled state.

Default

no interface

Parameters

ip-int-name

Values: 1 to 32 characters (must start with a letter)

address

Syntax

address {ip-address/mask | ip-address netmask} [broadcast {all-ones | host-ones}]

no address {ip-address/mask | ip-address netmask}

Context

config>service>ies>interface

Description

This command assigns an IP address, IP subnet, and broadcast address format to an IES IP interface.

An IP address must be assigned to each IES IP interface. An IP address and a mask combine to create a local IP prefix. The defined IP prefix must be unique within the context of the routing instance. The IP prefix cannot overlap with other existing IP prefixes defined as local subnets on other IP interfaces in the same routing context within the 7705 SAR.

By default, no IP address or subnet association exists on an IP interface until it is explicitly created.

Default

no address

Parameters

ip-address

Values: 1.0.0.0 to 223.255.255.255

/: the forward slash is a parameter delimiter that separates the ip-address portion of the IP address from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-address, the ‟/”, and the mask parameter. If a forward slash does not immediately follow the ip-address, a dotted-decimal mask must follow the prefix.

mask

Values: 1 to 32 (mask length of 32 is reserved for system IP addresses)

netmask

the subnet mask in dotted-decimal notation

Values: 0.0.0.0 to 255.255.255.255 (network bits all 1 and host bits all 0)

broadcast

overrides the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones, which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert to the default broadcast address of host-ones.

The broadcast format on an IP interface can be specified when the IP address is assigned or changed.

This parameter does not affect the type of broadcasts that can be received by the IP interface. A host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-ones) will be received by the IP interface.

all-ones: specifies that the broadcast address used by the IP interface for this IP address is 255.255.255.255 (also known as the local broadcast)

host-ones: specifies that the broadcast address used by the IP interface for this IP address is the subnet broadcast address. This is an IP address that corresponds to the local subnet described by the IP address and mask with all host bits set to 1. This IP address is the default broadcast address used by an IP interface.

allow-directed broadcasts

Syntax

[no] allow-directed broadcasts

Context

config>service>ies>interface

Description

This command enables the forwarding of directed broadcasts out of the IP interface.

A directed broadcast is a packet received on a local router interface destined for the subnet broadcast address of another IP interface. The allow-directed-broadcasts command on an IP interface enables or disables the transmission of packets destined for the subnet broadcast address of the egress IP interface.

When enabled, a frame destined for the local subnet on this IP interface is sent as a subnet broadcast out this interface.

Note: Allowing directed broadcasts is a well-known mechanism used for denial-of-service attacks.

By default, directed broadcasts are not allowed and are discarded at this egress IP interface.

The no form of the command disables directed broadcasts forwarding out of the IP interface.

Default

no allow-directed broadcasts

arp-retry-timer

Syntax

arp-retry-timer ms-timer

no arp-retry-timer

Context

config>service>ies>interface

Description

This command specifies the length of time, in 100s of milliseconds, that the system waits before reissuing a failed ARP request.

The no form of the command resets the interval to the default value.

Default

50 (in 100s of ms)

Parameters

ms-timer

the time interval, in 100s of milliseconds, the system waits before retrying a failed ARP request

Values: 1 to 300

arp-timeout

Syntax

arp-timeout seconds

no arp-timeout

Context

config>service>ies>interface

Description

This command configures the minimum interval, in seconds, that an ARP entry learned on the IP interface is stored in the ARP table. ARP entries are automatically refreshed when an ARP request or gratuitous ARP is seen from an IP host. Otherwise, the ARP entry is aged from the ARP table.

If the arp-timeout value is set to 0 s, ARP aging is disabled.

The no form of the command reverts to the default value.

Note: The 7705 SAR will attempt to refresh an ARP entry 30 s prior to its expiry. This refresh attempt occurs only if the ARP timeout is set to 45 s or more.

Default

no arp-timeout

Parameters

seconds

the minimum number of seconds a learned ARP entry is stored in the ARP table, expressed as a decimal integer. A value of 0 specifies that the timer is inoperative and learned ARP entries will not be aged.

Values: 0 to 65535

Default: 14400 s (4 h)

bfd

Syntax

bfd {transmit-interval} [receive receive-interval] [multiplier multiplier] [type np]

no bfd

Context

config>service>ies>interface

config>service>ies>if>ipv6

Description

Default

no bfd

Parameters

transmit-interval

the number of milliseconds between consecutive BFD sent messages

Values: 10 to 100000

Default: 100

receive-interval

the number of milliseconds between consecutive BFD received messages

Values: 10 to 100000

Default: 100

multiplier

the number of consecutive BFD messages that must be missed before the interface is brought down

Values: 3 to 20

Default: 3

type np: controls the value range of the transmit-interval and receive-interval parameters. If the type np option is not specified, the range of the transmit-interval and receive-interval parameter values is from 100 ms to 100000 ms. If the type np option is specified, the range of the transmit-interval and receive-interval parameter values is from 10 ms to 1000 ms, with the restriction that the maximum receiving detection time for the missing BFD packets must be less than or equal to 3000 ms. The maximum receiving detection time is the receive-interval parameter multiplied by the multiplier parameter.

Note: The BFD session must be disabled before the type np parameter can be changed.

dhcp

Syntax

dhcp

Context

config>service>ies>interface

Description

This command enables the context to configure DHCP parameters.

gi-address

Syntax

gi-address ip-address [src-ip-addr]

no gi-address

Context

config>service>ies>if>dhcp

Description

This command configures the gateway interface address for the DHCP Relay Agent. By default, the GIADDR used in the relayed DHCP packet is the primary address of an interface. Specifying the GIADDR allows the user to choose a secondary address.

Default

no gi-address

Parameters

ip-address

the IP address of the gateway interface in dotted-decimal notation

Values: a.b.c.d (host bits must be 0)

src-ip-addr: specifies that the GIADDR is to be used as the source IP address for DHCP relay packets

option

Syntax

[no] option

Context

config>service>ies>if>dhcp

Description

This command enables DHCP Option 82 (Relay Agent Information Option) parameters processing and enters the context for configuring Option 82 suboptions.

The no form of this command returns the system to the default.

Default

no option

action

Syntax

action {replace | drop | keep}

no action

Context

config>service>ies>if>dhcp>option

Description

This command configures the Relay Agent Information Option (Option 82) processing.

The no form of this command returns the system to the default value.

Default

keep

Parameters

replace: in the upstream direction (from the user), the Option 82 field from the router is inserted in the packet (overwriting any existing Option 82 field). In the downstream direction (toward the user), the Option 82 field is stripped (in accordance with RFC 3046).

drop: the DHCP packet is dropped if an Option 82 field is present, and a counter is incremented

keep

the existing information is kept in the packet and the router does not add any additional information. In the downstream direction, the Option 82 field is not stripped and is forwarded toward the client.

The behavior is slightly different in the case of Vendor Specific Options (VSOs). When the keep parameter is specified, the router will insert its own VSO into the Option 82 field. This will only be done if the incoming message already has an Option 82 field.

If no Option 82 field is present, the router will not create the Option 82 field. In this case, no VSO will be added to the message.

circuit-id

Syntax

circuit-id [ascii-tuple | ifindex | sap-id | vlan-ascii-tuple]

no circuit-id

Context

config>service>ies>if>dhcp>option

Description

This command sends either an ASCII tuple or the interface index (If Index) on the specified SAP ID in the circuit-id suboption of the DHCP packet.

If disabled, the circuit-id suboption of the DHCP packet is left empty.

The no form of the command returns the system to the default.

Default

ascii-tuple

Parameters

ascii-tuple: specifies that the ASCII-encoded concatenated tuple, which consists of the access node identifier, service ID, and interface name, separated by ‟/”, will be used

ifindex: specifies that the interface index will be used. The If Index of a router interface can be displayed using the command show>router>if>detail.

sap-id: specifies that the SAP ID will be used

vlan-ascii-tuple: specifies that the format will include VLAN ID and dot1p bits in addition to what is already included in ascii-tuple. The format is supported on dot1q and qinq ports only. Therefore, when the Option 82 bits are stripped, dot1p bits will be copied to the Ethernet header of an outgoing packet.

remote-id

Syntax

remote-id [mac | string string]

no remote-id

Context

config>service>ies>if>dhcp>option

Description

This command sends the MAC address of the remote end (typically the DHCP client) in the remote-id suboption of the DHCP packet. This command identifies the host at the other end of the circuit.

If disabled, the remote-id suboption of the DHCP packet is left empty.

The no form of this command returns the system to the default.

Default

remote-id

Parameters

mac: specifies that the MAC address of the remote end is encoded in the suboption

string: the remote ID

vendor-specific option

Syntax

[no] vendor-specific-option

Context

config>service>ies>if>dhcp>option

This command enables the sending of the service ID in the vendor-specific suboption of the DHCP relay packet.

The no form of the command disables the sending of the service ID.

string

Syntax

string text

no string

Context

config>service>ies>if>dhcp>option>vendor-specific-option

Description

This command specifies the string in the vendor-specific suboption of the DHCP relay packet.

The no form of the command reverts to the default value.

Default

no string

Parameters

text: any combination of ASCII characters up to 32 characters in length. If spaces are used in the string, the entire string must be enclosed within double quotes.

system-id

Syntax

[no] system-id

Context

config>service>ies>if>dhcp>option>vendor-specific-option

Description

This command specifies whether the system ID is encoded in the vendor-specific suboption of the DHCP relay packet.

server

Syntax

server server1 [server2...(up to 8 max)]

no server

Context

config>service>ies>if>dhcp>option

Description

This command specifies a list of servers where requests will be forwarded. The list of servers can be entered either as IP addresses or fully qualified domain names. There must be at least one server specified for DHCP relay to work. If there are multiple servers, the request is forwarded to all of the servers in the list.

There can be a maximum of 8 DHCP servers configured.

Default

no server

Parameters

server: the DHCP server IP address

trusted

Syntax

[no] trusted

Context

config>service>ies>if>dhcp>option

Description

As specified in RFC 3046, DHCP Relay Agent Information Option, a DHCP request where the giaddr is 0.0.0.0 and that contains a Option 82 field in the packet, should be discarded unless it arrives on a ‟trusted” circuit. If trusted mode is enabled on an IP interface, the Relay Agent (the router) will modify the request giaddr to be equal to the ingress interface and forward the request.

This behavior only applies when the action in the Relay Agent Information Option is ‟keep”. In the case where the Option 82 field is being replaced by the Relay Agent (action = ‟replace”), the original Option 82 information is lost, and therefore there is no reason to enable the trusted option.

The no form of this command returns the system to the default.

Default

not enabled

hold-time

Syntax

hold-time

Context

config>service>ies>interface

Description

This command enables the CLI context to configure interface hold-up or hold-down timers.

l4-load-balancing

Syntax

l4-load-balancing hashing-algorithm

no l4-load-balancing

Context

config>service>ies>interface>load-balancing

Description

This command configures Layer 4 load balancing at the interface level. Configuration must be done on the ingress network interface (that is, the interface on the node that the packet is received on). When enabled, Layer 4 source and destination port fields of incoming TCP/UDP packets are included in the hashing calculation to determine the distribution of packets.

You can add additional fields to generate more randomness and more equal distribution of packets with the teid-load-balancing command.

The default configuration on the interface is to match the Layer 4 load-balancing configuration in the config>system context. Using this command to modify Layer 4 load-balancing configuration on an interface overrides the system-wide load-balancing settings for that interface.

Parameters

hashing-algorithm

specifies that Layer 4 source and destination port fields are included in or excluded from the hashing calculation

Values

includeL4: include Layer 4 source and destination port fields in the hashing calculation for TCP/UDP packets

excludeL4: exclude Layer 4 source and destination port fields in the hashing calculation for TCP/UDP packets

config>service>ies>if>ipv6

Description

This command associates the interface with a local DHCP server configured on the system. A routed VPLS interface may not be associated with a local DHCP server.

The no form of the command removes the association of the interface with the local DHCP server.

Default

n/a

Parameters

local-server-name

the name of the local DHCP server

Values: up to 32 alphanumeric characters

local-proxy-arp

Syntax

[no] local-proxy-arp

Context

config>service>ies>interface

Description

This command enables local proxy ARP on the interface.

Local proxy ARP allows the 7705 SAR to respond to ARP requests received on an interface for an IP address that is part of a subnet assigned to the interface. The router responds to all requests for IP addresses within the subnet with its own MAC address and forwards all traffic between the hosts in the subnet.

Local proxy ARP is used on subnets where hosts are prevented from communicating directly.

When local-proxy-arp is enabled, ICMP redirects on the ports associated with the service are automatically blocked.

Default

no local-proxy-arp

loopback

Syntax

[no] loopback

Context

config>service>ies>interface

Description

This command specifies that the interface is a loopback interface that has no associated physical interface. If this command is enabled, a SAP cannot be defined on the interface.

Default

no loopback

mac

Syntax

mac ieee-address

no mac [ieee-address]

Context

config>service>ies>interface

Description

This command assigns a specific MAC address to an IES IP interface.

The no form of the command returns the MAC address to the default value.

Default

the physical MAC address associated with the Ethernet interface on which the SAP is configured (default MAC address assigned to the interface by the system)

Parameters

ieee-address: a 48-bit MAC address in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff, where aa, bb, cc, dd, ee, and ff are hexadecimal numbers and cannot be all zeros. Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.

proxy-arp-policy

Syntax

proxy-arp-policy policy-name [policy-name...(up to 5 max)]

no proxy-arp-policy

Context

config>service>ies>interface

Description

This command enables proxy ARP on the interface and specifies an existing policy statement that controls the flow of routing information by analyzing match and action criteria. The policy statement is configured in the config>router>policy-options context (see the 7705 SAR Router Configuration Guide, ‟Route Policy Command Reference, Route Policy Options”). When proxy ARP is enabled, the 7705 SAR responds to ARP requests on behalf of another device.

Default

no proxy-arp-policy

Parameters

policy-name: the route policy statement name. Allowed values are any string up to 32 characters long composed of printable, 7-bit ASCII characters. If the string contains special characters (such as #, $, or spaces), the entire string must be enclosed within double quotes. The policy statement must already be defined.

remote-proxy-arp

Syntax

[no] remote-proxy-arp

Context

config>service>ies>interface

Description

This command enables remote proxy ARP on the interface, allowing a router on one network to respond to ARP requests intended for another node that is physically located on another network. The router effectively pretends to be the destination node by sending an ARP response to the originating node that associates the router’s MAC address with the destination node’s IP address (acts as a proxy for the destination node). The router then takes responsibility for routing traffic to the real destination.

Default

no remote-proxy-arp

secondary

Syntax

secondary {ip-address/mask | ip-address netmask} [broadcast all-ones | host-ones] [igp-inhibit]

no secondary {ip-address/mask | ip-address netmask}

Context

config>service>ies>interface

Description

This command assigns an secondary IP address, IP subnet, and broadcast address format to the interface.

Default

no secondary

Parameters

ip-address

the IP address of the IP interface. The ip-address portion of the secondary command specifies the IP host address that will be used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.

Values

a.b.c.d

(1.0.0.0 to 223.255.255.255 (with support of /31 subnets))

The ‟/” (forward slash) is a parameter delimiter that separates the ip-address portion of the IP address from the mask, which defines the scope of the local subnet. No spaces are allowed between the ip-address, the ‟/”, and the mask. If a forward slash does not immediately follow the ip-address, a dotted-decimal mask must follow the prefix.

mask

the subnet mask length when the IP prefix is specified in CIDR notation. When the IP prefix is specified in CIDR notation, a forward slash separates the ip-address from the mask. The mask indicates the number of bits used for the network portion of the IP address; the remainder of the IP address is used to determine the host portion of the IP address.

Values: 0 to 32 (a mask length of 32 is reserved for loopback addresses, including system IP addresses)

netmask

the subnet mask, in dotted-decimal notation. When the IP prefix is not specified in CIDR notation, a space separates the ip-address from a traditional dotted-decimal mask. The netmask parameter indicates the complete mask that will be used in a logical ‟AND” function to derive the local subnet of the IP address.

Values

128.0.0.0 to 255.255.255.254

(network bits all 1 and host bits all 0)

(255.255.255.255 is reserved for system IP addresses)

broadcast

the optional broadcast parameter overrides the default broadcast address used by the IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified for the IP address, the default value is host-ones, which indicates a subnet broadcast address. Use this parameter to change the broadcast address to all-ones or revert to a broadcast address of host-ones.

The broadcast format on an IP interface can be specified when the IP address is assigned or changed.

Default: host-ones

all-ones: specifies that the broadcast address used by the IP interface for this IP address will be 255.255.255.255, also known as the local broadcast

host-ones

specifies that the broadcast address used by the IP interface for this IP address will be the subnet broadcast address. This is an IP address that corresponds to the local subnet described by the ip-address and the mask, or the mask with all the host bits set to binary one. This is the default broadcast address used by an IP interface.

The broadcast parameter within the secondary command does not have a negation feature, which is usually used to revert a parameter to the default value. To change the broadcast type to host-ones after being changed to all-ones, the secondary command must be executed with the broadcast parameter defined.

igp-inhibit: specifies that this secondary IP interface should not be recognized as a local interface by the running IGP. For OSPF and IS-IS, this means that the secondary IP interface will not be injected and used as a passive interface and will not be advertised as an internal IP interface into the IGP link state database. For RIP, this means that the secondary IP interface will not source RIP updates.

static-arp

Syntax

static-arp ip-address ieee-address

no static-arp ip-address [ieee-address]

static-arp ieee-address unnumbered

no static-arp [ieee-address] unnumbered

Context

config>service>ies>interface

Description

This command configures a static ARP entry associating an IP address with a MAC address for the core router instance. This static ARP appears in the core routing ARP table. A static ARP can only be configured if it exists on the network attached to the IP interface.

If an entry for a particular IP address already exists and a new MAC address is configured for the IP address, the existing MAC address is replaced by the new MAC address.

A router interface can only have one static ARP entry configured for it.

Static ARP is used when a 7705 SAR needs to know about a device on an interface that cannot or does not respond to ARP requests. Therefore, the 7705 SAR configuration can specify to send a packet with a particular IP address to the corresponding ARP address.

The no form of the command removes a static ARP entry.

Default

no static-arp

Parameters

ip-address: the IP address for the static ARP in dotted-decimal notation

ieee-mac-address: the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff, where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC, and non-IEEE reserved MAC addresses.

unnumbered: specifies the static ARP MAC addresses for an unnumbered interface. Unnumbered interfaces also support dynamic ARP. If this parameter is configured, it overrides any dynamic ARP.

static-nat-inside

Syntax

[no] static-nat-inside

Context

config>service>ies>interface

Description

This command configures an interface as an inside (private) interface.

By default, all interfaces are outside (public) interfaces. The no form of this command returns the interface to the default setting.

Default

no static-nat-inside

tcp-mss

Syntax

tcp-mss value

no tcp-mss

Context

config>service>ies>interface

config>service>ies>if>ipv6

Description

This command configures the maximum segment size (MSS) in a TCP SYN or SYN-ACK packet during the establishment of a TCP connection. A tcp-mss value can be specified on an ingress interface, egress interface, or both. When configured on two interfaces, the smaller of the two values is used. If the TCP SYN packet has no TCP MSS field, the 7705 SAR assigns it the MSS value configured on the interface and recalculates the IP checksum. If the TCP SYN or SYN-ACK packet has an MSS field and the value is greater than the value configured on the interface, the 7705 SAR overwrites the packet MSS value with the lower value. If the MSS value is less than the value configured on the interface, the packet MSS value does not change. See the 7705 SAR Router Configuration Guide, ‟TCP MSS Configuration and Adjustment”, for more information.

This command is supported on interfaces with IPv4 and IPv6 traffic, and a different MSS value can be configured for the IPv4 and IPv6 interfaces. This command is not supported on IPSec public interfaces in IES.

Default

no tcp-mss

Parameters

value

the MSS, in bytes, to be used in a TCP SYN or SYN-ACK packet

Values: 384 to 9732

unnumbered

Syntax

unnumbered {ip-int-name | ip-address}

no unnumbered

Context

config>service>ies>interface

Description

This command configures an IP interface as an unnumbered interface and specifies an IP address or interface name to be used for the interface. Unnumbered interfaces are point-to-point interfaces that are not explicitly configured with a dedicated IP address and subnet; instead, they borrow (or link to) an IP address from another interface on the system (the system IP address, another loopback interface, or any other numbered interface) and use it as the source IP address for packets originating from the interface.

By default, no IP address exists on an IP interface until it is explicitly created.

The no form of the command removes the IP address assignment from the IP interface.

Default

no unnumbered

Parameters

ip-int-name | ip-address

the IP interface name or address to associate with the unnumbered IP interface

Values

ip-int-name: 1 to 32 characters (must start with a letter)

ip-address: a.b.c.d

IES Service VRRP Commands

vrrp

Syntax

vrrp virtual-router-id [owner] [passive]

no vrrp virtual-router-id

Context

config>service>ies>interface

config>service>ies>if>ipv6

Description

This command creates or edits a virtual router ID (VRID) on the service IP interface. A virtual router ID is internally represented in conjunction with the IP interface name. This allows the virtual router ID to be used on multiple IP interfaces while representing different virtual router instances.

Two VRIDs can be defined on an IP interface. One, both, or none may be defined as owner.

The no form of this command removes the specified virtual router ID from the IP interface. This terminates VRRP participation for the virtual router and deletes all references to the virtual router ID. The virtual router ID does not need to be shut down in order to remove the virtual router instance.

Default

n/a

Parameters

virtual-router-id

specifies a new virtual router ID or one that can be modified on the IP interface

Values: 1 to 255

owner: keyword used to identify this virtual router instance as owning the virtual router IP addresses. If the owner keyword is not specified at the time of VRID creation, the vrrp backup command must be used to define the virtual router IP addresses. The owner keyword is not required when entering the VRID for editing purposes. When created as owner, a VRID on an IP interface cannot have the owner parameter removed. The VRID must be deleted, and then recreated without the owner keyword, to remove ownership.

passive: keyword used to identify this virtual router instance as passive, owning the virtual router IP addresses. A passive VRID does not send or receive VRRP advertisement messages and is always in either the master state (if the interface is operationally up), or the initialize state (if the interface is operationally down). The passive keyword is not required when entering the VRID for editing purposes. When a VRID on an IP interface is created as passive, the parameter cannot be removed from the VRID. The VRID must be deleted, and then recreated without the passive keyword, to remove the parameter.

authentication-key

Syntax

authentication-key [authentication-key | hash-key] [hash | hash2]

no authentication-key

Context

config>service>ies>if>vrrp

Description

This command assigns a simple text password authentication key to generate master VRRP advertisement messages and validate received VRRP advertisement messages.

If the command is re-executed with a different password key defined, the new key is used immediately. If a no authentication-key command is executed, the password authentication key is restored to the default value. The authentication-key command may be executed at any time.

To change the current in-use password key on multiple virtual router instances:

identify the current master
shut down the virtual router instance on all backups
execute the authentication-key command on the master to change the password key
execute the authentication-key command and no shutdown command on each backup

The no form of this command restores the default value of the key.

Default

The authentication data field contains the value 0 in all octets.

Parameters

authentication-key

identifies the simple text password used when VRRP Authentication Type 1 is enabled on the virtual router instance. Type 1 uses a string 8 octets long that is inserted into all transmitted VRRP advertisement messages and compared against all received VRRP advertisement messages. The authentication data fields are used to transmit the key.

The authentication-key parameter is expressed as a string consisting up to eight alphanumeric characters. Spaces must be contained in quotation marks (‟ ”). The quotation marks are not considered part of the string.

The string is case-sensitive and is left-justified in the VRRP advertisement message authentication data fields. The first field contains the first four characters with the first octet containing the first character. The second field holds the fifth through eighth characters. Any unspecified portion of the authentication data field is padded with the value 0 in the corresponding octet.

Values

any 7-bit printable ASCII character

exceptions: double quote ASCII 34

carriage return ASCII 13

line feed ASCII 10

tab ASCII 9

backspace ASCII 8

hash-key

can be any combination of ASCII characters up to 11 characters in length (encrypted) for a hash key or up to 110 characters for a hash2 key. If spaces are used in the string, the entire string must be enclosed in quotation marks (‟ ”).

This option is useful when a user must configure the parameter, but for security purposes, the actual unencrypted key value is not provided.

hash: specifies that the key is entered in an encrypted form. If the hash keyword is not used, the key is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in encrypted form in the configuration file with the hash keyword specified.

hash2: specifies that the key is entered in a more complex encrypted form. If the hash2 keyword is not used, the less-encrypted hash form is assumed.

backup

[no] bfd-enable interface interface-name dst-ip ip-address

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command assigns a BFD session that provides a heartbeat mechanism for a VRRP instance. Only one BFD session can be assigned to a VRRP instance, but multiple VRRP instances can use the same BFD session.

BFD controls the state of the associated interface. By enabling BFD on a protocol interface, the state of the protocol interface is tied to the state of the BFD session between the local node and the remote node. The parameters used for the BFD session are set with the bfd-enable command under the IP interface specified in this command.

The no form of this command removes BFD from the configuration.

Default

n/a

Parameters

service-id

specifies the service ID of the interface running BFD

Values: 1 to 2147483690 or service-name

interface-name: specifies the name of the interface running BFD

ip-address

specifies the destination address to be used for the BFD session

Values

ipv4-address: a.b.c.d

ipv6-address: x:x:x:x:x:x:x:x (eight 16-bit pieces)

mac

Syntax

mac mac-address

no mac

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command assigns a specific MAC address to an IES IP interface.

The no form of the command returns the MAC address of the IP interface to the default value.

Default

the physical MAC address associated with the Ethernet interface that the SAP is configured on (the default MAC address assigned to the interface, assigned by the system)

Parameters

mac-address: specifies the 48-bit MAC address for the static ARP in the form aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff, where aa, bb, cc, dd, ee, and ff are hexadecimal numbers. Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.

master-int-inherit

Syntax

[no] master-int-inherit

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command allows the master instance to dictate the master down timer (non-owner context only).

The master down interval is the time that the master router can be down before the backup router takes over. The master down interval is used to specify the master down timer. If the master down timer expires, the backup virtual router enters the master state. See the "Master Down Interval" in the "VRRP" chapter of the 7705 SAR Router Configuration Guide for details.

Default

no master-int-inherit

message-interval

Syntax

message-interval {[seconds] [milliseconds milliseconds]}

no message-interval

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command sets the advertisement timer and indirectly sets the master down timer on the virtual router instance. The message-interval setting must be the same for all virtual routers with the same VRID. Any VRRP advertisement message received with an advertisement interval field different from the virtual router instance configured message-interval value is silently discarded.

Configuring the message interval value can be done in three ways: using only the milliseconds value, using only the seconds value, or using a combination of the two values. Message Interval Configuration Ranges shows the ranges for each way of configuring the message interval.

Table 4. Message Interval Configuration Ranges
Configuration	IPv4	IPv6
Using milliseconds value only	100 to 900 ms	10 to 990 ms
Using seconds value only	1 to 255 s	1 to 40 s
Using combination milliseconds and seconds values	1 s 100 ms to 255 s 900 ms (1.1 s to 255.9 s)	1 s 10 ms to 40s 990 ms (1.01 s to 40.99 s)
Default setting	1 s	1 s

The message-interval command is available for both non-owner and owner virtual routers. If the message-interval command is not executed, the default message interval is 1 s.

The no form of this command restores the default message-interval value of 1 s to the virtual router instance.

Default

1 s

Parameters

seconds

the time interval, in seconds, between sending advertisement messages.

Values

IPv4: 1 to 255

IPv6: 1 to 40

milliseconds

the time interval, in milliseconds, between sending advertisement messages. This parameter is not supported on non-redundant chassis.

Values

IPv4: 100 to 900

IPv6: 10 to 990

ntp-reply

Syntax

[no] ntp-reply

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command enables the reception of and response to Network Time Protocol (NTP) requests directed at the VRRP virtual IP address. This behaviour only applies to the router currently acting as the master VRRP.

The no form of this command disables NTP requests from being processed.

Default

no ntp-reply

ping-reply

Syntax

[no] ping-reply

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command enables the non-owner master to reply to ICMP echo requests directed to the virtual router instance IP addresses. The ping request can be received on any routed interface.

Ping must not have been disabled at the management security level (either on the parent IP interface or based on the ping source host address). When ping reply is not enabled, ICMP echo requests to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to ICMP echo requests regardless of the setting of the ping reply configuration.

The ping-reply command is only available for non-owner virtual routers.

The no form of this command restores the default operation of discarding all ICMP echo request messages destined for the non-owner virtual router instance IP addresses.

Default

no ping-reply

policy

Syntax

policy vrrp-policy-id

no policy

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command associates a VRRP priority control policy with the virtual router instance (non-owner context only). VRRP policies are defined under the config>vrrp>policy context. For details, see the ‟VRRP” chapter in the 7705 SAR Router Configuration Guide.

Default

n/a

Parameters

vrrp-policy-id

specifies a VRRP priority control policy. The VRRP policy ID must already exist in the system for the policy command to be successful.

Values: 1 to 9999

preempt

Syntax

[no] preempt

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command provides the ability to override an existing non-owner master with a virtual router backup that has a higher priority. Enabling preempt mode enhances the operation of the base priority and VRRP policy ID definitions on the virtual router instance. If the virtual router cannot preempt an existing non-owner master, the effect of the dynamic changing of the in-use priority is greatly diminished.

The preempt command is only available for non-owner VRRP virtual routers. The owner cannot be preempted because the priority of non-owners can never be higher than the owner. The owner always preempts all other virtual routers when it is available.

Non-owner backup virtual router instances only preempt when preempt is set and the current master has an in-use message priority value less than the backup virtual router instance in-use priority.

A master non-owner virtual router only allows itself to be preempted when the incoming VRRP advertisement message priority field value is one of the following:

greater than its in-use priority value
equal to the in-use priority value, and the source IP address (primary IP address) is greater than its primary IP address

The no form of this command prevents a non-owner virtual router instance from preempting another, less-desirable, virtual router.

Default

preempt

priority

Syntax

priority priority

no priority

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command configures a specific priority value for the virtual router instance. In conjunction with the optional policy command, the base priority derives the in-use priority of the virtual router instance.

The priority command is only available for non-owner VRRP virtual routers. The priority of owner virtual router instances is permanently set to 255 and cannot be changed. For non-owner virtual router instances, if the priority command is not executed, the base priority is set to 100.

The no form of this command restores the default value of 100.

Parameters

priority

specifies the priority used by the virtual router instance. If a VRRP priority control policy is not defined, the base priority is in-use priority for the virtual router instance.

Values: 1 to 254

Default: 100

ssh-reply

Syntax

[no] ssh-reply

Context

config>service>ies>if>vrrp

Description

This command enables the non-owner master to reply to SSH requests directed at the IP addresses of the virtual router instances. The SSH request can be received on any routed interface. SSH must not have been disabled at the management security level (either on the parent IP interface or based on the SSH source host address). Proper login and CLI command authentication are enforced.

When the ssh-reply command is not enabled, SSH packets to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to SSH requests regardless of the SSH reply configuration.

The ssh-reply command is only available for non-owner VRRP virtual routers.

The no form of this command restores the default operation of discarding all SSH packets destined for the non-owner virtual router instance IP addresses.

Default

no ssh-reply

standby-forwarding

Syntax

[no] standby-forwarding

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command allows the forwarding of packets by a standby router when sent to the virtual router MAC address.

The no form of the command specifies that a standby router should not forward traffic sent to the virtual router MAC address. The standby router should forward traffic sent to the real MAC address of the standby router.

Default

no standby-forwarding

telnet-reply

Syntax

[no] telnet-reply

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command enables the non-owner master to reply to TCP port 23 Telnet requests directed at the IP addresses of the virtual router instance. The Telnet request can be received on any routed interface. Telnet must not have been disabled at the management security level (either on the parent IP interface or based on the Telnet source host address). Proper login and CLI command authentication are enforced.

If the telnet-reply command is not enabled, TCP port 23 Telnet packets to non-owner master virtual IP addresses are silently discarded.

Non-owner backup virtual routers never respond to Telnet requests regardless of the Telnet reply configuration.

The telnet-reply command is only available for non-owner VRRP virtual routers.

The no form of this command restores the default operation of discarding all Telnet packets destined for the non-owner virtual router instance IP addresses.

Default

no telnet-reply

traceroute-reply

Syntax

[no] traceroute-reply

Context

config>service>ies>if>vrrp

config>service>ies>if>ipv6>vrrp

Description

This command enables a non-owner master to reply to traceroute requests directed to the virtual router instance IP addresses. The command is valid only if the VRRP virtual router instance associated with this entry is a non-owner. A non-owner backup virtual router never responds to traceroute requests regardless of the traceroute reply status.

Default

no traceroute-reply

IES Service SAP Commands

sap

Syntax

[no] sap sap-id [create]

Context

config>service>ies>interface

Description

This command creates a SAP within an IES service. Each SAP must be unique.

All SAPs must be explicitly created with the create keyword. If no SAPs are created within a service or an IP interface, a SAP does not exist on that object.

To edit SAP parameters, enter an existing SAP without the create keyword.

A SAP can only be associated with a single service. The SAP is owned by the service in which it was created. A SAP can only be defined on a port that has been configured as an access port in the config>port port-id context using the mode access command. See the 7705 SAR Interface Configuration Guide, ‟Access Ports”.

If a port is shut down, all SAPs on that port become operationally down. When a service is shut down, SAPs for the service are not displayed as operationally down although all traffic traversing the service are discarded. The operational state of a SAP is relative to the operational state of the port on which the SAP is defined.

The following SAP types are supported:

PPP IPCP encapsulation of an IPv4 packet for IES (RFC 1332)
MLPPP bundle
LAG
Ethernet SAPs supporting null, dot1q, and qinq

To configure an IES interface SAP that is used for a public IPSec tunnel interface, see sap in Service Interface Tunnel Commands.

If the IES interface has been configured as a loopback interface with the loopback command, a SAP cannot be defined on the interface.

The no form of this command deletes the SAP with the specified port. When a SAP is deleted, all configuration parameters for the SAP are also deleted.

Default

no sap

Parameters

sap-id: specifies the physical port identifier portion of the SAP definition. See SAP ID Configurations for a full list of SAP IDs.

create: keyword used to create a SAP instance. The create keyword requirement can be enabled/disabled in the environment>create context.

accounting-policy

Syntax

accounting-policy acct-policy-id

no accounting-policy [acct-policy-id]

Context

config>service>ies>if>sap

Description

This command creates the accounting policy context that can be applied to a SAP. An accounting policy must be defined before it can be associated with a SAP. If the policy ID does not exist, an error message is generated.

A maximum of one accounting policy can be associated with a SAP at one time. Accounting policies are configured in the config>log context.

The no form of this command removes the accounting policy association from the SAP, and the accounting policy reverts to the default.

Default

no accounting-policy

Parameters

acct-policy-id

the accounting policy ID as configured in the config>log>accounting-policy context

Values: 1 to 99

collect-stats

Syntax

[no] collect-stats

Context

config>service>ies>if>sap

Description

This command enables accounting and statistical data collection for the SAP. When applying accounting policies, the data, by default, is collected in the appropriate records and written to the designated billing file.

When the no collect-stats command is issued, the statistics are still accumulated by the CSM. However, the CPU does not obtain the results and write them to the billing file. If a subsequent collect-stats command is issued, the counters written to the billing file include all the traffic while the no collect-stats command was in effect.

Default

collect-stats

egress

Syntax

egress

Context

config>service>ies>if>sap

Description

This command enables the context to configure egress SAP QoS policies and IP filter policies.

If no sap-egress QoS policy is defined, the system default sap-egress QoS policy is used for egress processing. If no egress IP filter policy is defined, no filtering is performed.

ingress

Syntax

ingress

Context

config>service>ies>if>sap

Description

This command enables the context to configure ingress SAP QoS policies and IP filter policies.

If no sap-ingress QoS policy is defined, the system default sap-ingress QoS policy is used for ingress processing. If no ingress IP filter policy is defined, no filtering is performed.

agg-rate-limit

Syntax

agg-rate-limit agg-rate [cir cir-rate]

no agg-rate-limit

Context

config>service>ies>if>sap>egress

config>service>ies>if>sap>ingress

Description

This command sets the aggregate rate limits (PIR and CIR) for the SAP. The agg-rate sets the PIR value. The cir-rate sets the CIR value. When aggregate rate limits are configured on a second-generation (Gen-2) Ethernet adapter card, the scheduler mode must be set to 16-priority. On a third-generation (Gen-3) Ethernet adapter card, the scheduler mode is always 4-priority. For information on adapter card generations, see the ‟Evolution of Ethernet Adapter Cards, Modules, and Platforms” section in the 7705 SAR Interface Configuration Guide.

Configuring the cir-rate is optional. If a cir-rate is not entered, then the cir-rate is set to its default value (0 kb/s). If a cir-rate has been set and the agg-rate is changed without re-entering the cir-rate, the cir-rate automatically resets to 0 kb/s. For example, to change the agg-rate from 2000 to 1500 while maintaining a cir-rate of 500, use the command agg-rate-limit 1500 cir 500.

If the specified SAP is a LAG SAP, agg-rate and cir-rate is configured regardless of the scheduler mode setting on Gen-2 or Gen-3 hardware. If the active port is on a Gen-3 card or platform, agg-rate and cir-rate are applicable. If the active port is on a Gen-2 card or platform, agg-rate and cir-rate apply when the scheduler mode is set to 16-priority. For details on the behavior of a mix-and-match LAG SAP, see the ‟LAG Support on Third-Generation Ethernet Adapter Cards, Ports, and Platforms” and ‟Network LAG Traffic Management” sections in the 7705 SAR Interface Configuration Guide.

The no form of the command sets the agg-rate to the maximum and the cir-rate to 0 kb/s.

Default

no agg-rate-limit

Parameters

agg-rate

sets the PIR for the aggregate of all the queues on the SAP. The max keyword applies the maximum physical port rate possible.

Values: 1 to 10000000 kb/s, or max

Default: max

cir-rate

sets the CIR for the aggregate of all the queues on the SAP

Values: 0 to 10000000 kb/s, or max

Default: 0 kb/s

filter

Syntax

filter ip ip-filter-id

filter ipv6 ipv6-filter-id

no filter [ip ip-filter-id | ipv6 ipv6-filter-id]

Context

config>service>ies>if>sap>egress

config>service>ies>if>sap>ingress

Description

This command associates an IPv4 or IPv6 filter policy with an egress or ingress IES SAP.

Filter policies control the forwarding and dropping of packets based on IP matching criteria. Only one filter can be applied to a SAP at a time.

The ip-filter-id or ipv6-filter-id must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message is displayed.

The no form of the command removes any configured filter ID association with the SAP. The filter policy cannot be deleted until it is removed from all SAPs where it is applied.

Default

no filter

Parameters

ip-filter-id

specifies the IPv4 filter policy. The filter ID or filter name must already exist within the created IP filters.

Values: 1 to 65535 or filter-name (up to 64 characters)

ipv6-filter-id

specifies the IPv6 filter policy. The filter ID or filter name must already exist within the created IP filters.

Values: 1 to 65535 or filter-name (up to 64 characters)

Note: For information about configuring IP filter IDs, see the 7705 SAR Router Configuration Guide, ‟Filter Policies”.

match-qinq-dot1p

Syntax

match-qinq-dot1p {top | bottom}

no match-qinq-dot1p

Context

config>service>ies>if>sap>ingress

Description

This command specifies which dot1q tag position (top or bottom) in a qinq-encapsulated packet should be used when QoS evaluates dot1p classification.

The no form of the command restores the default dot1p evaluation behavior for the SAP, which means that the inner (bottom) tag (second tag) dot1p bits are used for classification.

By default, the dot1p bits from the inner tag service-delineating dot1q tag are used.

Match-QinQ-Dot1p Matching Behavior shows which set of dot1p bits are used for QoS purposes when match-qinq-dot1p is configured. To use the table, find the row that represents the settings for Port/SAP Type and Match-QinQ-Dot1q Setting. Use the Existing Packet Tags column to identify which dot1q tags are available in the packet. Then use the P-bits Used for Match column to identify which dot1q tag contains the dot1p bits that are used for QoS dot1p classification.

Default

no match-qinq-dot1p

Parameters

top: the top parameter and bottom parameter are mutually exclusive. When the top parameter is specified, the outer tag's dot1p bits (topmost P-bits) are used (if existing) to match any dot1p dot1p-value entries.

bottom

the bottom parameter and top parameter are mutually exclusive. When the bottom parameter is specified, the bottommost P-bits (second tag’s P-bits) are used (if existing) to match any dot1p dot1p-value entries.

qinq-mark-top-only

Syntax

[no] qinq-mark-top-only

Context

config>service>ies>if>sap>egress

Description

When enabled, the qinq-mark-top-only command specifies which P-bits to mark during packet egress. When disabled, both sets of P-bits are marked. When enabled, only the P-bits in the top Q-tag are marked. The no form of the command is the default state (disabled).

Dot1p Re-marking Behavior for the QinQ-mark-top-only Command shows the dot1p re-marking behavior for different egress port type/SAP type combinations and qinq-mark-top-only state, where ‟False” represents the default (disabled) state.

If a new tag is pushed, the dot1p bits of the new tag are zero (unless the new tag is re-marked by the egress policy. The dot1p bits are configured using the dot1p parameter under the config>qos context.

Table 6. Dot1p Re-marking Behavior for the QinQ-mark-top-only Command
Egress Port Type/SAP Type	QinQ-mark-top-only State	Egress P-Bits Marked or Re-marked
Null ¹	n/a	None

Notes:

This port type/SAP type is supported by the following services: Epipe, Ipipe, VPLS, IES, and VPRN.
This port type/SAP type is supported by the following services: Epipe and VPLS.
Normally, when a new tag is pushed, the dot1p bits of the new tag is zero, unless the P-bits are remarked by the egress policy. However, an exception to this occurs when the egress SAP type is X.Y and only one new outer tag must be pushed. In this case, the new outer tag has its dot1p bits set to the inner tag's dot1p bits.

Default

no qinq-mark-top-only

qos

Syntax

qos policy-id

no qos

Context

config>service>ies>if>sap>egress

config>service>ies>if>sap>ingress

Description

This command associates a QoS policy with an ingress or egress IES SAP.

QoS ingress and egress policies are important for the enforcement of SLA agreements. The policy ID must be defined before associating the policy with a SAP. If the policy-id does not exist, an error is returned.

The qos command associates both ingress and egress QoS policies. The qos command allows only ingress policies to be associated on the SAP ingress and only egress policies to be associated on the SAP egress. Attempts to associate a QoS policy of the wrong type returns an error.

Only one ingress and one egress QoS policy is associated with an IES SAP at one time. Attempts to associate a second QoS policy of a specified type returns an error.

By default, no specific QoS policy is associated with the SAP for ingress or egress; therefore, the default QoS policy is used.

The no form of this command removes the QoS policy association from the SAP, and the QoS policy reverts to the default.

Parameters

policy-id

associates the ingress or egress policy ID with the SAP. The policy ID or name must already exist.

Values: 1 to 65535, or policy-name (up to 64 characters)

scheduler-mode

Syntax

scheduler-mode {4-priority | 16-priority}

Context

config>service>ies>if>sap>egress

config>service>ies>if>sap>ingress

Description

This command sets the scheduler mode for the SAP and is part of the hierarchical QoS (H-QoS) feature on the 7705 SAR.

If the mode is 4-priority, then the SAP is considered an unshaped 4-priority SAP and the agg-rate-limit cannot be changed from its default values.

If the mode is 16-priority and the agg-rate limit parameters are configured to be non-default values, then the SAP is considered a shaped SAP. If the agg-rate limit parameters are left in their default settings, the SAP is considered an unshaped, 16-priority SAP.

This command is blocked on third-generation (Gen-3) Ethernet adapter cards and platforms, such as the 6-port Ethernet 10Gbps Adapter card and the 7705 SAR-X, which only support 4-priority scheduling mode.

If the specified SAP is a LAG SAP, scheduler-mode can be configured but is not applied to Gen-3 adapter cards and platforms.

Default

4-priority

Parameters

4-priority: sets the scheduler mode for the SAP to be 4-priority mode

16-priority: sets the scheduler mode for the SAP to be 16-priority mode

shaper-group

Syntax

[no] shaper-group shaper-group-name [create]

Context

config>service>ies>if>sap>egress

config>service>ies>if>sap>ingress

Description

This command applies a shaper group to a SAP. The shaper group must already be created and must be within the shaper policy assigned to the Ethernet MDA (for ingress) or port (for egress). A shaper group is a dual-rate aggregate shaper used to shape aggregate access ingress or egress SAPs at a shaper group rate. Multiple aggregate shaper groups ensure fair sharing of available bandwidth among different aggregate shapers.

The default shaper group cannot be deleted.

The no form of this command removes the configured shaper-group.

Default

shaper-group ‟default”

Parameters

shaper-group-name: the name of the shaper group. To access the default shaper group, enter ‟default”.

create: keyword used to create a shaper group

IES Service Spoke SDP Commands

spoke-sdp

Syntax

spoke-sdp sdp-id:vc-id [create]

no spoke-sdp sdp-id:vc-id

Context

config>service>ies>interface

Description

This command binds a service to an existing Service Distribution Point (SDP).

A spoke SDP is treated like the equivalent of a traditional bridge ‟port”, where flooded traffic received on the spoke SDP is replicated on all other ‟ports” (other spoke SDPs or SAPs) and not transmitted on the port it was received on.

The SDP has an operational state that determines the operational state of the SDP within the service. For example, if the SDP is administratively or operationally down, the SDP for the service is down.

The SDP must already be defined in the config>service>sdp context in order to associate it with a service. If the sdp sdp-id is not already configured, an error message is generated. If the sdp-id does exist, a binding between that sdp-id and the service is created.

SDPs must be explicitly associated and bound to a service. If an SDP is not bound to a service, no far-end devices can participate in the service.

Class-based forwarding is not supported on a spoke SDP used for termination on an IES or VPRN service. All packets are forwarded over the default LSP.

The no form of this command removes the SDP binding from the service. The SDP configuration is not affected; only the binding of the SDP to the service. Once the binding is removed, no packets are forwarded to the far-end router. The spoke SDP must be shut down first before it can be deleted from the configuration.

Default

no sdp-id is bound to a service

Special Cases

IES: only one sdp-id can be bound to an IES

Parameters

sdp-id

the SDP identifier

Values: 1 to 17407

vc-id

the virtual circuit identifier

Values: 1 to 4294967295

egress

Syntax

egress

Context

config>service>ies>if>spoke-sdp

Description

This command enables the context to configure egress SDP parameters.

vc-label

Syntax

vc-label egress-vc-label

no vc-label [egress-vc-label]

Context

config>service>ies>if>spoke-sdp>egress

Description

This command configures the static MPLS VC label used by the 7705 SAR to send packets to the far-end device in this service via this SDP.

Parameters

egress-vc-label

a VC egress value that indicates a specific connection

Values: 16 to 1048575

ingress

Syntax

ingress

Context

config>service>ies>if>spoke-sdp

Description

This command enables the context to configure ingress SDP parameters.

filter

Syntax

filter ip ip-filter-id

no filter

Context

config>service>ies>if>spoke-sdp>ingress

Description

This command associates an IP filter policy with an ingress spoke SDP. Filter policies control the forwarding and dropping of packets based on IP or MAC matching criteria.

The filter policy must already be defined before the filter command is executed. If the filter policy does not exist, the operation fails and an error message is returned.

In general, filters applied to ingress spoke SDPs apply to all packets on the spoke SDP. One exception is that non-IP packets are not applied to IP match criteria, so the default action in the filter policy applies to these packets.

The no form of this command removes any configured filter ID association with the spoke SDP.

Parameters

ip-filter-id

specifies the IP filter policy. The filter ID or filter name must already exist within the created IP filters.

Values: 1 to 65535 or filter-name (up to 64 characters)

vc-label

Syntax

vc-label ingress-vc-label

no vc-label [ingress-vc-label]

Context

config>service>ies>if>spoke-sdp>ingress

Description

This command configures the static MPLS VC label used by the far-end device to send packets to the 7705 SAR in this service via this SDP.

Parameters

ingress-vc-label

a VC ingress value that indicates a specific connection

Values: 2048 to 18431

Routed VPLS Commands

vpls

Syntax

vpls service-name

no vpls

Context

config>service>ies>if

Description

This command within the IP interface context binds the IP interface to the specified VPLS service name.

The system does not attempt to resolve the service name until the IP interface is placed into the administratively up state (no shutdown). After the IP interface is administratively up, the system scans the available VPLS services that have the allow-ip-int-binding flag set for a VPLS service associated with the service name. If the IP interface is already in the administratively up state, the system immediately attempts to resolve the specified service name.

Parameters

service-name: specifies the service name that the system attempts to resolve to an allow-ip-int-binding enabled VPLS service associated with the service name. The specified service name is an ASCII string of up to 32 characters.

ingress

Syntax

ingress

Context

config>service>ies>if>vpls

Description

This command within the VPLS binding context defines the routed IPv4 optional filter override.

v4-routed-override-filter

Syntax

v4-routed-override-filter ip-filter-id

no v4-routed-override-filter

Context

config>service>ies>if>vpls>ingress

Description

This command specifies an IPv4 filter ID applied to all ingress packets entering the VPLS service. The filter overrides the existing ingress IPv4 filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional, and if not defined or removed, the IPv4 routed packets use the existing ingress IPv4 filter on the VPLS virtual ports.

The no form of the command removes the IPv4 routed override filter from the ingress IP interface.

Default

n/a

Parameters

ip-filter-id

specifies the IPv4 filter policy. The filter ID or filter name must already exist within the created IP filters.

Values: 1 to 65535 or filter-name (up to 64 characters)

v6-routed-override-filter

Syntax

v6-routed-override-filter ipv6-filter-id

no v6-routed-override-filter

Context

config>service>ies>if>vpls>ingress

Description

This command specifies an IPv6 filter ID applied to all ingress packets entering the VPLS service. The filter overrides the existing ingress IPv6 filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional, and if it is not defined or it is removed, the IPv6 routed packets use the existing ingress IPv6 filter on the VPLS virtual ports.

The no form of the command removes the IPv6 routed override filter from the ingress IP interface.

Default

n/a

Parameters

ip-address

Syntax

ip-address ip-address [to ip-address] interface ip-int-name

no ip-address

Context

config>service>ies>zone>nat>pool>entry

Description

This command configures the source IP address or IP address range to which packets that match NAT policy are routed using NAT. An interface can also be configured, in which case all packets that match NAT policy are routed to the interface IP address. If the interface IP address is changed dynamically, NAT is updated accordingly. Only one IP address can be associated with an IP interface. Source IP addresses and interfaces cannot be used together in a single NAT pool.

The IP address for the interface must be entered in dotted-decimal notation. The maximum IP address range limit is 255.

The no form of the command removes the IP address assignment. The no form of this command can only be performed when the IP interface is administratively shut down. Shutting down the IP interface brings the interface operationally down.

Parameters

ip-address

the source IP address to be used by NAT. The ip-address portion of the ip-address command specifies the IP host address that is used by the IP interface within the subnet. This address must be unique within the subnet and specified in dotted-decimal notation.

Values: 1.0.0.0 to 223.255.255.255

ip-int-name: the name of the interface to be used by NAT

port

Syntax

port port [to port]

no port

Context

config>service>ies>zone>nat>pool>entry

Description

This command configures the UDP/TCP port or port range. Packets that match NAT policy undergo network port address translation (NPAT) and are routed to their source UDP/TCP port. Configuring a UDP/TCP port pool requires an IP-address pool because the 7705 SAR does not support port address translation (PAT) alone.

The no form of this command deletes the port or port range.

Parameters

port: the UDP/TCP port or range of ports to which NPAT is applied

name

Syntax

name pool-name

no name

Context

config>service>ies>zone>nat>pool

the name of the pool. If the string contains special characters (such as #, $, or spaces), the entire string must be enclosed within double quotes.

Values: 1 to 32 characters (must start with a letter).

policy

Syntax

policy {policy-id | policy-name}

no policy

Context

config>service>ies>zone

Description

This command sets the policy to be used by the security zone to build its matching criteria for incoming packets.

The no form of this command deletes the specified policy.

Parameters

policy-id

the number of the referenced policy

Values: 1 to 65535

policy-name: the name of the referenced policy

IES Raw Socket IP Transport Configuration Commands

ip-transport

Syntax

ip-transport ipt-id [create]

no ip-transport ipt-id

Context

config>service>ies

Description

This command creates an IP transport subservice within an IES service. An IP transport subservice is used to transmit serial raw socket data to and from a local host and remote host.

All IP transport subservices must be explicitly created using the create keyword. An IP transport subservice is owned by the service within which it is created. An IP transport subservice can only be associated with a single service. The create keyword is not needed when editing parameters for an existing IP transport subservice. An IP transport subservice must be first shut down before changes can be made to the configured parameters.

The no form of this command deletes the IP transport subservice with the specified ipt-id. When an IP transport subservice is deleted, all configured parameters for the IP transport subservice are also deleted.

Default

no ip-transport

Parameters

ipt-id

the IP transport subservice physical port identifier. The ipt-id must reference an RS-232 serial port that has been configured as a socket and has its encapsulation type set to raw. See the 7705 SAR Interface Configuration Guide, ‟Serial Commands”, for more information.
