Internet Enhanced Service on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

This chapter provides information about Internet Enhanced Services support on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.

IES service overview

Internet Enhanced Service (IES) is a routed connectivity service where the subscriber communicates with an IP router interface to send and receive Internet traffic. An IES has one or more logical IP routing interfaces each with a SAP which acts as the access point to the subscriber's network.

IES allows IP interfaces to participate in the same routing instance used for service network core routing connectivity. IES services require that the IP addressing scheme used by the subscriber be unique between other provider addressing schemes and potentially the entire Internet. While IES is part of the routing domain, the usable IP address space may be limited. This allows a portion of the service provider address space to be reserved for service IP provisioning, and be administered by a separate, but subordinate address authority.

IP interfaces defined within the context of an IES service must have a SAP associated as the access point to the subscriber network. Multiple IES services are created to segregate subscriber owned IP interfaces.

The following figure shows a visual representation of IES.

Figure 1. Internet Enhanced Service

The IES service provides in-band management connectivity. Other features include:

  • Multiple IES services are created to separate IP interfaces.

  • More than one IES service can be created for a single customer ID.

  • More than one IP interface can be created within a single IES service ID. All IP interfaces created within an IES service ID belong to the same customer.

IES features

This section describes various general service features and any special capabilities or considerations as they relate to IES services.

IP interfaces

IES customer IP interfaces can be configured with most of the options found on the core IP interfaces. The advanced configuration options supported are:

  • ICMP Options

  • VRRP - for IES services with more than one IP interface (available only in network mode)

In network mode, configuration options found on core IP interfaces not supported on IES IP interfaces are:

  • NTP broadcast receipt

SAPs

IPv6 support for IES IP interfaces

IES IPv6 IP interfaces provide IPv6 connectivity in the routing base instance. It can be used to connect IPv6 networks over an IPv4 cloud using the IPv6 Provider Edge Router over MPLS (6PE) functionality. For more information about the 6PE, see the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Router Configuration Guide, ‟IPv6 Provider Edge Router over MPLS (6PE)”.

IPv4 and IPv6 route table lookup entries are shared.

A separate route table (or a block in the route table) is used for IPv6 /128-bit prefix route lookup. A limited amount of IPv6 /128 prefixes route lookup entries is supported. The software enables lookups in this table by default (that is, no user configuration is required to enable Ipv6 /128-bit route lookup). A limited amount of IPv6 /128 prefixes route lookup entries is supported.

Encapsulations

The following SAP encapsulation is supported on IES services:

  • Ethernet null

  • Ethernet dot1q

  • Ethernet QinQ

  • Ethernet QinQ (access-uplink QinQ SAP)

Routing protocols

IES IP interfaces are restricted to routing protocols that can be configured on the interface. IES IP interfaces support the following routing protocols:

  • OSPF

  • IS-IS

  • eBGP for the IPv4 and IPv6 address families (MPBGP is not supported)

  • IGMP

  • PIM

  • BFD

Note:

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

CPE connectivity check

Static routes are used within many IES services. Unlike dynamic routing protocols, there is no way to change the state of routes based on availability information for the associated CPE. CPE connectivity check adds flexibility so that unavailable destinations will be removed from the service provider's routing tables dynamically and minimize wasted bandwidth.

The availability of the far-end static route is monitored through periodic polling. The polling period is configured. If the poll fails a specified number of sequential polls, the static route is marked as inactive.

An ICMP ping mechanism is used to test the connectivity. If the connectivity check fails and the static route is deactivated, the router will continue to send polls and re-activate any routes that are restored.

QoS policies

When applied to 7210 SAS IES services, service ingress QoS policies only create the unicast queues defined in the policy. The multi-point queues are not created on the service. With IES services, service egress QoS policies function as with other services where the class-based queues are created as defined in the policy.

Note that MAC, IPv4, and IPv6 criteria can be used in the QoS policies for traffic classification in an IES.

CPU QoS for IES access interfaces in network mode

Traffic bound to CPU received on IES access interfaces are policed/rate-limited and queued into CPU queues. The software allocates a policer per IP application or a set of IP applications, for rate-limiting CPU bound IP traffic from all IES access SAPs. The policers CIR/PIR values are set to appropriate values based on feature scaling and these values are not user configurable. The software allocates a set of queues for CPU bound IP traffic from all IES access SAPs. The queues are either shared by a set of IP applications or in some cases allocated to an IP application. The queues are shaped to appropriate rate based on feature scaling. The shaper rate is not user-configurable.

Note:

  • The instance of queues and policers used for traffic received on network port IP interfaces is different for traffic received from access port IP interfaces. Additionally the network CPU queues are accorded higher priority than the access CPU queues. This is done to provide better security and mitigate the risk of access traffic affecting the network side.

  • IP DSCP marking of self-generated traffic is assigned by software on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.

Filter policies

IP filter policies with IPv4 or IPv6 match entries can be applied to IES services.

VRRP support for IES IP interfaces in network mode

Virtual Router Redundancy Protocol (VRRP) for IPv4 is defined in IETF RFC 3768, Virtual Router Redundancy Protocol. VRRP describes a method of implementing a redundant IP interface shared between two or more routers on a common LAN segment, allowing a group of routers to function as one virtual router. When this IP interface is specified as a default gateway on hosts directly attached to this LAN, the routers sharing the IP interface prevent a single point of failure by limiting access to this gateway address. For more information about the use of VRRP, refer to the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Router Configuration Guide.

VRRP is supported for IES IPv4 interfaces in network mode only. VRRP is not supported in access-uplink mode. It is also not supported for IPv6 interfaces in network or access-uplink mode.

Note:

Only one VRRP instance for each IP interface is supported on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.

Configuring an IES service with CLI

This section provides information to configure IES services using the command line interface.

Basic configuration

The most basic IES service configuration has the following entities:

  • customer ID (refer to Configuring customer accounts)

  • an interface to create and maintain IP routing interfaces within IES service ID

  • a SAP on the interface specifying the access port and encapsulation values

The following is a sample configuration output of an IES service on ALA-50.

*A:ALA-50>config>service# info
----------------------------------------------
ies 1000 customer 50 create
            description "to internet"
            interface "to-web" create
                address 10.1.1.1/24
                sap 1/1/10:100.* create
                exit
            exit
            no shutdown
----------------------------------------------
*A:ALA-50>config>service#

Common configuration tasks

This section provides a brief overview of the tasks that must be performed to configure IES services and provides the CLI commands:

  1. Associate an IES service with a customer ID.

  2. Associate customer ID with the service.

  3. Assign an IP address.

  4. Create an interface.

  5. Define SAP parameters on the interface

  6. Select nodes and ports.

  7. Optional - select filter policies (configured in the config>filter context).

  8. Enable service.

                no shutdown
----------------------------------------------
*A:K-SASK12>config>service>ies>if#
Configuring IES SAP parameters

A SAP is a combination of a port and encapsulation parameters which identifies the service access point on the interface and within the router. Each SAP must be unique within a router.

When configuring IES access SAP parameters, a default QoS policy is applied to each SAP ingress. Additional QoS policies must be configured in the config>qos context. Filter policies are configured in the config>filter context and must be explicitly applied to a SAP. There are no default filter policies.

The following is a sample IES SAP configuration output.

----------------------------------------------
*A:ALA-A>config>service>ies>if# info
----------------------------------------------
address 10.10.36.2/24
sap 1/1/3:100 create
ingress
qos 101
exit
exit
----------------------------------------------
*A:ALA-A>config>service>ies>if#
Configuring VRRP

Configuring VRRP parameters on an IES interface is optional. VRRP can be configured in either owner or non-owner mode. The owner is the VRRP router whose virtual router IP address is the same as the real interface IP address. This is the router that responds to packets addressed to one of the IP addresses for ICMP pings, TCP connections, and related addresses. All other virtual router instances participating in this message domain should have the same VRID configured and cannot be configured as an owner.

The following is a sample IES interface VRRP owner configuration output.

config>service>ies> info
#----------------------------------------------
...
    interface ‟vrrpowner”
       address 10.10.10.23/24
       vrrp 1 owner
           backup 10.10.10.23
           authentication-key "vh48lOV7Hs2H6lrMHg2aMJJnZStHwwyO" hash2
       exit
    exit
...
#----------------------------------------------
config>service>ies#

Service management tasks

This section describes the service management tasks.

Modifying IES service parameters

Existing IES service parameters in the CLI or NMS can be modified, added, removed, enabled or disabled. The changes are applied immediately to all services when the charges are applied.

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

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

The following is a sample modified service.

*A:ALA-A>config>service>ies# info
----------------------------------------------
ies 1000 customer 50 create
           description ‟This is a new description”
           interface ‟to-web” create
               address 10.1.1.1/24
               mac 00:dc:98:1d:00:00


               sap 1/1/5:0.* create
               exit
           exit
           no shutdown
exit
----------------------------------------------
*A:ALA-A>config>service#

Deleting an IES service

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

Use the following syntax to delete an IES service.

config>service#
[no] ies service-id
shutdown
[no] interface ip-int-name
shutdown
[no] sap sap-id
shutdown

Disabling an IES service

Use the following syntax to shut down the IES service without deleting the service parameters.

config>service> ies service-id
shutdown

Re-enabling an IES service

Use the following syntax o re-enable an IES service that was shut down.

config>service> ies service-id
[no] shutdown
Example:
config>service# ies 2000
config>service>ies# no shutdown
config>service>ies# exit

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.

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

Note:

  • Refer to the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Basic System Configuration Guide for information about how to allocate addresses toward IP subnets using the configure system resource-profile router max-ip-subnets CLI command.

  • Before using IPv6, resources for IPv6 routes must be allocated. Refer to the 7210 SAS-D, Dxp, K 2F1C2T, K 2F6C4T, K 3SFP+ 8C Basic System Configuration Guide for information about how to use the configure system resource-profile router max-ipv6-routes CLI command.

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

Special Cases
IES

The default administrative status of an IES service is down. While the service is down, all its associated virtual router interfaces are operationally down. The administrative state of the service is not reflected in the administrative state of the virtual router interface.

For example if the following are true:

  • an IES service is operational and an associated interface is shut down

  • the IES service is administratively shutdown and brought back up

  • the interface shutdown remains in administrative shutdown state

A service is regarded as operational if 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 the SAP and all packets received on the SAP are dropped while incrementing the packet discard counter.

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command creates or edits an IES service instance.

The ies command is used to create or maintain an IES. If the service-id does not exist, a context for the service is created. If the service-id exists, the context for editing the service is entered.

IP interfaces defined within the context of an IES service ID must have a SAP created.

When a service is created, the customer keyword and customer-id must be specified to associate the service with a customer. The customer-id must already exist having been created using the customer command in the service context. After a service has been created with a customer association, it is not possible to edit the customer association. The service must be deleted and recreated with a new customer association.

After a service is created, the use of the customer customer-id is optional for navigating into the service configuration context. Attempting to edit a service with the incorrect customer-id specified results in an error.

More than one IP interface may be created within a single IES service ID.

By default, no IES service instances exist until they are explicitly created.

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

Specifies the unique service identification number or string identifying the 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 used for every 7210 SAS on which this service is defined.

Values

service-id: 1 to 2147483648

customer customer-id

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

Values

1 to 2147483647

vpn vpn-id

Specifies the VPN ID assigned to the service.

Values

Description

This command configures a service name that can be used in other configuration commands and show commands that reference the service. This helps the service provider/administrator to identify and manage services within the 7210 SAS platforms.

All services are required to assign a service ID to initially create a service. However, either the service ID or the service name can be used to identify and reference a specific service when it is initially created.

Parameters
service-name

Specifies a unique service name, up to 64 characters, to identify the service. Service names may not begin with an integer (0-9).

Description

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

The interface command is used to create and maintain 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 default routing.

Interface names are case sensitive and must be unique within the group of defined IP interfaces defined for config service ies interface (that is, the network core router instance). Interface names must not 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.

By default, 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 IP the interface and all the associated configuration. The interface must be administratively shutdown before issuing the no interface command.

For IES services, the IP interface must be shut down before the SAP on that interface may be removed.

Parameters
ip-int-name

Specifies the name of the IP interface. Interface names must be unique within the group of defined IP interfaces for config router interface and config service ies interface commands. An interface name cannot be in the form of an IP address. Interface names can be from 1 to 32 alphanumeric characters. If the string contains special characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.

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

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command assigns an IP address and IP subnet, to an IES IP router interface. Only one IP address can be associated with an IP interface. An IP address must be assigned to each IES IP interface. An IP address and a mask are used together to create a local IP prefix. The defined IP prefix must be unique within the context of the routing instance. It cannot overlap with other existing IP prefixes defined as local subnets on other IP interfaces in the same routing context within the 7210 SAS.

The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or traditional dotted decimal notation. The show commands display CIDR notation and is 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 this command removes the IP address assignment from the IP interface. When the no address command is entered, the interface becomes operationally down.

The operational state is a read-only variable and the only controlling variables are the address and admin states. The address and admin states are independent and can be set independently. If an interface is in an adminstratively up state and an address is assigned, it becomes operationally up.

Parameters
ip-address

Specifies the IP address of the IP interface. The ip-address portion of the 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. Allowed values are IP addresses in the range 1.0.0.0 to 223.255.255.255 (with support of /31 subnets).

Values

a.b.c.d (no multicast/broadcast address)

/

The forward slash is a parameter delimiter and 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-length parameter. If a forward slash is not immediately following the ip-address, a dotted decimal mask must follow the prefix.

mask

Specifies 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-length parameter. The mask length parameter 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. A mask length of 32 is reserved for system IP addresses.

Values

0 to 32

netmask

Specifies 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 mask parameter indicates the complete mask that will be used in a logical ‟AND” function to derive the local subnet of the IP address. Allowed values are dotted decimal addresses in the range 128.0.0.0 to 255.255.255.254. A mask of 255.255.255.255 is reserved for system IP addresses.

Values

a.b.c.d (network bits all 1 and host bits all 0)

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures the minimum time in seconds an ARP entry learned on the IP interface will be 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 arp-timeout is set to a value of zero seconds, ARP aging is disabled.

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

Default

14400 seconds

Parameters
seconds

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

Values

0 to 65535

delayed-enable

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command delays making the interface operational by the specified number of seconds. In environments with many subscribers, it can take time to synchronize the subscriber state between peers when the subscriber-interface is enabled (for example, after a reboot). To ensure that the state has time to be synchronized, the delayed-enable timer can be specified. The optional init-only parameter can be added to use this timer only after a reboot.

Default

no delayed-enable

Parameters
seconds

Specifies the number of seconds to delay before the interface is operational.

Values

1 to 1200

init-only

Keyword to specify to use this timer only after a reboot.

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command specifies that the associated interface is a loopback interface that has no associated physical interface. As a result, the associated IES interface cannot be bound to a SAP.

Configure an IES interface as a loopback interface by issuing the loopback command instead of the sap command. The loopback flag cannot be set on an interface where a SAP is already defined and a SAP cannot be defined on a loopback interface.

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures a static address resolution protocol (ARP) entry associating an IP address or an unnumbered 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 or unnumbered address already exists and a new MAC address is configured for the IP address, the existing MAC address is replaced with the new MAC address.

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

Parameters
ip-address

Specifies the IP address for the static ARP in IP address dotted decimal notation.

ieee-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.

unnumbered

Keyword that specifies the static ARP MAC for an unnumbered interface. Unnumbered interfaces support dynamic ARP. When this command is configured, it overrides any dynamic ARP.

unnumbered
Syntax

no unnumbered

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures an IP interface as an unnumbered interface and specifies the IP address to be used for the interface.

To conserve IP addresses, unnumbered interfaces can be configured. The address used when generating packets on this interface is the configured ip-address parameter.

An error message is generated when an unnumbered interface is configured and an IP address already exists on this interface.

The no form of this command removes the IP address from the interface, effectively removing the unnumbered property. The interface must be shut down before the no unnumbered command is issued to delete the IP address from the interface or an error message is generated.

Default

no unnumbered

Parameters
ip-int-name | ip-address

Specifies the IP interface name or IP address with which to associate the unnumbered IP interface in dotted decimal notation. The configured IP address must exist on this node. Nokia recommends using the system IP address as it is not associated with a particular interface and is therefore always reachable. The system IP address is the default if ip-int-name or ip-address is not configured.

Syntax

vpls service-name

Context

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

The system does not attempt to resolve the service name provided until the IP interface is placed into the administratively up state (no shutdown). When 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 name. If the service name is bound to the service name when the IP interface is already in the administratively up state, the system immediately attempts to resolve the specific name.

If a VPLS service is found associated with the name and with the allow-ip-int-binding flag set, the IP interface is attached to the VPLS service allowing routing to and from the service virtual ports when the IP interface is operational.

A VPLS service associated with the specified name that does not have the allow-ip-int-binding flag set or a non-VPLS service associated with the name will be ignored and will not be attached to the IP interface.

If the service name is applied to a VPLS service after the service name is bound to an IP interface and the VPLS service allow-ip-int-binding flag is set at the time the name is applied, the VPLS service is automatically resolved to the IP interface if the interface is administratively up or when the interface is placed in the administratively up state.

If the service name is applied to a VPLS service without the allow-ip-int-binding flag set, the system does not attempt to resolve the applied service name to an existing IP interface bound to the name. To rectify this condition, the flag must first be set and then the IP interface must enter or reenter the administratively up state.

While the specified service name may be assigned to only one service context in the system, it is possible to bind the same service name to more than one IP interface. If two or more IP interfaces are bound to the same service name, the first IP interface to enter the administratively up state (if currently administratively down) or to reenter the administratively up state (if currently administratively up) when a VPLS service is configured with the name and has the allow-ip-int-binding flag set will be attached to the VPLS service. Only one IP interface is allowed to attach to a VPLS service context. No error is generated for the remaining non-attached IP interfaces using the service name.

When an IP interface is attached to a VPLS service, the name associated with the service cannot be removed or changed until the IP interface name binding is removed. Also, the allow-ip-int-binding flag cannot be removed until the attached IP interface is unbound from the service name. Unbinding the service name from the IP interface causes the IP interface to detach from the VPLS service context. The IP interface may then be bound to another service name or a SAP or SDP binding may be created for the interface using the sap or spoke-SDP commands on the interface.

Parameters
service-name

Mandatory parameter that specifies the service name that the system will attempt to resolve to an allow-ip-int-binding enabled VPLS service associated with the name. The specified name is expressed as an ASCII string comprised of up to 32 characters. It does not need to already be associated with a service and the system does not check to ensure that multiple IP interfaces are not bound to the same name.

Description

This command configures an IP filter ID that is applied to all ingress packets entering the VPLS service. The filter overrides any existing ingress IP filter applied to SAP or SDP bindings for packets associated with the routing IP interface. The override filter is optional and when it is not defined or is removed, the IP routed packets use any existing ingress IP filter on the VPLS virtual port.

The no form of this command removes the IP routed override filter from the ingress IP interface. When removed, the IP ingress routed packets within a VPLS service attached to the IP interface use the IP ingress filter applied to the packets virtual port, when defined.

Parameters
ip-filter-id

Specifies the ID for the IP filter policy. Allowed values are an integer that corresponds to a previously created IP filter policy in the configure>filter>ip-filter context.

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command creates a SAP within a service. A SAP is a combination of port and encapsulation parameters that identify the service access point on the interface and within the router. Each SAP must be unique.

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

Enter an existing SAP without the create keyword to edit SAP parameters. The SAP is owned by the service in which it was created.

A SAP can be associated with only a single service. A SAP can only be defined on a port that has been configured as an access port and access uplink port using the configure port port number ethernet mode access uplink command.

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 are also deleted.

Special Cases
IES

A SAP is defined within the context of an IP routed interface. Each IP interface is limited to a single SAP definition. Attempts to create a second SAP on an IP interface will fail and generate an error; the original SAP will not be affected.

Parameters
sap-id

Specifies the physical port identifier portion of the SAP definition. See Common CLI command descriptions for command syntax.

port-id

Specifies the physical port ID in the slot/mda/port format.

If the card in the slot has Media Dependent Adapters (MDAs) installed, the port-id must be in the slot_number/MDA_number/port_number format; for example 1/1/1 specifies port 1 on MDA 1 in slot 1.

The port-id must reference a valid port type. The port must be configured as an uplink access port.

Description

This command associates a filter policy with an ingress or egress SAP. Filter policies control the forwarding and dropping of packets based on the matching criteria.

The filter command associates a filter policy that has a specified ip-filter-id with an ingress or egress SAP. 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 SAPs (ingress or egress) apply to all packets on the SAP. One exception is that non-IP packets are not applied to the 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 SAP. The filter ID is not removed from the system.

Special Cases
IES

Only IP filters are supported on an IES IP interface, and the filters only apply to routed traffic.

Parameters
ip

Keyword indicating the filter policy is an IP filter.

Description

Commands in this context configure DHCP parameters.

option
Syntax

[no] option

Context

config>service>ies>if>dhcp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

The no form of this command reverts the system to the default values.

Default

no option

action
Syntax

action [dhcp-action] {replace | drop | keep}

no action

Context

config>service>ies>if>dhcp>option

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

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

Default

the default is to keep the existing information intact

Parameters
dhcp-action

Specifies the DHCP option action.

replace

Keyword to specify that, 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

Keyword to specify that the DHCP packet is dropped if an Option 82 field is present, and a counter is incremented.

keep

Keyword to specify that 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 sent on toward the client.

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

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

gi-address
Syntax

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

no gi-address

Context

config>service>ies>if>dhcp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures the gateway interface address for the DHCP relay. A subscriber interface can include multiple group interfaces with multiple SAPs. The GI address is needed when the router functions as a DHCP relay to distinguish between the different subscriber interfaces and potentially between the group interfaces defined.

By default, the GI address used in the relayed DHCP packet is the primary IP address of a normal IES interface. Specifying the GI address allows the user to choose a secondary address.

Default

no gi-address

Parameters
ip-address

Specifies the host IP address to be used for DHCP relay packets.

src-ip-addr

Keyword that specifies the source IP address to be used for DHCP relay packets.

circuit-id
Syntax

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

no circuit-id

Context

config>service>ies>if>dhcp>option

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures the router to send an ASCII-encoded tuple in the circuit-id suboption of the DHCP packet.

To send a tuple in the circuit ID, the action replace command must be configured in the same context.

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

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

Default

circuit-id

Parameters
ascii-tuple

Specifies that the ASCII-encoded concatenated tuple will be used, which consists of the access-node-identifier, service-id, and interface-name, separated by ‟|”.

ifindex

Specifies that the interface index will be used. The If Index of a router interface can be displayed using the show router interface detail command.

sap-id

Specifies that the SAP identifier will be used.

vlan-ascii-tuple

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

no qos

Context

config>service>ies>if>sap>egress

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command associates a Quality of Service (QoS) policy with an ingress SAP or IP interface.

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

Only one egress QoS policy can be associated with a SAP at one time. Attempts to associate a second QoS policy of a specific type returns an error.

By default, if no specific QoS policy is associated with the SAP for egress, 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 value.

Parameters
policy-id

Specifies the egress policy ID to associate with SAP on egress. The policy ID must already exist.

Values

1 to 65535

agg-shaper-rate

Description

This command specifies the aggregate rate for the SAP shaper. The aggregate SAP shaper is available to limit only the unicast traffic and the BUM traffic across all the FCs of the SAP configured to use ingress queues. Specify the CIR rate and the PIR rate. Users must not oversubscribe the total bandwidth available for use by ingress queues.

The no form of this command disables the use of the SAP aggregate rate shaper. That is, the SAP can use up the maximum bandwidth available.

Default

no aggregate-meter-rate

Context

config>service>ies>if>sap>ingress

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures the access SAP ingress aggregate policer. The rate of the SAP ingress aggregate policer must be specified. Users can optionally specify the burst size for the SAP aggregate policer. The aggregate policer monitors the ingress traffic on different FCs using policers to rate-limit the flow and determines the final disposition of the packet. The packet is either forwarded to an identified profile or dropped.

Note:

  • The sum of CIR of the individual FCs configured under the SAP cannot exceed the PIR rate configured for the SAP. Although the 7210 SAS software does not block this configuration, it is not recommended.

  • The queued traffic flows are not limited by the aggregate meter. That is, only metered flows can use the aggregate meter. Queued flows can use only aggregate shaper.

The following table lists the final disposition of the packet based on the operating rate of the per-FC policer and the per-SAP aggregate policer.

Context

config>service>ies>if>sap>ingress

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command associates a QoS policy with an ingress SAP or IP interface.

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

Only one ingress QoS policy can be associated with a SAP at one time. Attempts to associate a second QoS policy of a specific type returns an error.

By default, if no specific QoS policy is associated with the SAP for ingress, 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 value.

Parameters
policy-id

Specifies the ingress policy ID to associate with SAP on ingress. The policy ID must already exist.

Values

1 to 65535

Syntax

[no] local-proxy-arp

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command enables local proxy ARP. When local proxy ARP is enabled on an IP interface, the system responds to all ARP requests for IP addresses belonging to the subnet with its own MAC address, and therefore will become the forwarding point for all traffic between hosts in that subnet. When the local-proxy-arp command is enabled, ICMP redirects on the ports associated with the service are automatically blocked.

Default

no local-proxy-arp

local-dhcp-server

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures a local DHCP server. A local DHCP server can serve multiple interfaces but is limited to the routing context in which it was created.

Parameters
server-name

Specifies the name of local DHCP server.

create

Keyword used to create the server name. The create keyword requirement can be enabled or disabled in the environment>create context.

loopback
Syntax

[no] loopback

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command specifies that the interface is a loopback interface that has no associated physical interface. As a result, the associated IES interface cannot be bound to a SAP.

You can configure an IES interface as a loopback interface by issuing the loopback command instead of the sap command. The loopback flag cannot be set on an interface where a SAP is already defined, and a SAP cannot be defined on a loopback interface.

Syntax

ip-mtu octets

no ip-mtu

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command configures the IP maximum transmit unit (MTU) (packet) for this interface.

Because this connects a Layer 2 to a Layer 3 service, this parameter can be adjusted under the IES interface.

The MTU that is advertised from the IES size is the following:

MINIMUM ((SdpOperPathMtu - EtherHeaderSize), (Configured ip-mtu))

By default (for Ethernet network interface) if no ip-mtu is configured, it is (1568 - 14) = 1554.

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

Default

no ip-mtu

IES interface VRRP commands
vrrp
Syntax

vrrp virtual-router-id [owner]

no vrrp virtual-router-id

Context

config>service>ies>if

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

Two VRRP nodes can be defined on an IP interface. One, both, or none may be defined as an owner. The vrrp virtual-router-id context defines the configuration parameters for the VRID.

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

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 that defines the virtual router instance as an owner.

authentication-key
Syntax

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

no authentication-key

Context

config>service>ies>if>vrrp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

The authentication-key command is one of the few commands not affected by the presence of the owner keyword. If simple text password authentication is not required, this command is not required. 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, altering the simple text password used when authentication-type password authentication method is used by the virtual router instance. The authentication-type password command does not need to be executed before defining the authentication-key command.

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 key

By default, the authentication data field contains the value 0 in all 16 octets.

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

Parameters
authentication-key

Specifies the simple text password used when VRRP Authentication Type 1 is enabled on the virtual router instance. Type 1 uses a string eight 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 of up to eight alpha-numeric 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 (starting with IETF RFC bit position 0) 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

Specifies the hash key. The key can be any combination of ASCII characters up to 22 characters (encrypted). If spaces are used in the string, enclose the entire string 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

Keyword to specify the key is entered in an encrypted form. If the hash parameter 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 parameter specified.

hash2

Keyword to specify the key is entered in a more complex encrypted form. If the hash2 parameter is not used, the less encrypted hash form is assumed.

no message-interval

Context

config>service>ies>if>vrrp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

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 participating as a virtual router. Any VRRP advertisement message received with an Advertisement Interval field different from the virtual router instance configured message-interval value will be silently discarded.

This command is available in both non-owner and owner vrrp virtual-router-id nodal contexts. If the message-interval command is not executed, the default message interval of 1 second is used.

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

Parameters
seconds

Specifies the number of seconds that will transpire before the advertisement timer expires.

Values

1 to 255

Default

1

milliseconds

Specifies the milliseconds time interval between sending advertisement messages. This parameter is not supported on single-slot chassis.

Values

100 to 900

ping-reply
Syntax

[no] ping-reply

Context

config>service>ies>if>vrrp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

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 parental 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 ping reply configuration.

The ping-reply command is available only in non-owner vrrp virtual-router-id nodal context. If the ping-reply command is not executed, ICMP echo requests to the virtual router instance IP addresses are silently discarded.

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

Default

no ping-reply

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command associates a VRRP priority control policy with the virtual router instance (non-owner context only).

Parameters
vrrp-policy-id

Specifies a VRRP priority control policy.

Values

1 to 9999

preempt
Syntax

preempt

no preempt

Context

config>service>ies>if>vrrp

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

This command provides the ability to override an existing non-owner master to the virtual router instance. Enabling preempt mode is recommended for correct 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 affect of the dynamic changing of the in-use priority is greatly diminished.

The preempt command is available only in the non-owner vrrp virtual-router-id nodal context. The owner may not 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 virtual router instances only preempt when preempt is set and the current master has an in-use message priority value less than the virtual router instance in-use priority.

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

  • greater than the virtual router in-use priority value

  • equal to the in-use priority value and the source IP address (primary IP address) is greater than the virtual router instance primary IP address

The no form of this command prevents a non-owner virtual router instance from preempting another, less desirable virtual router. Use the preempt command to revert to the default mode.

Default

preempt

Platforms

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C

Description

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

The priority command is available only in the non-owner vrrp virtual-router-id nodal context. 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 reverts to the default value of 100.

Parameters
base-priority

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

Values

1 to 254

Default

100

They do not reflect actual ARP entries but are displayed along the interfaces ARP entry for easy lookup.

Parameters
ip-address

Specifies the IP address of the interface for which to display matching ARP entries.

Values

ipv4-address:

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

ipv6-address:

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

x:x:x:x:x:x:d.d.d.d

x: [0 to FFFF]H

d: [0 to 255]D

mac ieee-address

Displays only ARP entries in the ARP table with the specified 48-bit MAC address. The MAC address can be expressed 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.

Default

All MAC addresses.
