Overview of Filter Policies
Filter policies (or filters), also referred to as Access Control Lists (ACLs), are sets of rules that can be applied to network interfaces and services (VLL (Ethernet and IP), VPLS, VPRN and IES, and IES in-band management). Filter policies constrain network or user traffic based on match criteria and determine the action that will be invoked against the subject packet (that is, the default action can be either ‟drop” or ‟forward”).
The 7705 SAR supports seven types of filter policies:
IP filters
MAC filters
VLAN filters
CSM filters
IP exception filters
management access filters
match-list filters
The 7705 SAR also supports policy-based routing (PBR), which is based on IP filters, and multi-field classification (MFC).
IP, MAC, and VLAN filters scan all traffic and take the appropriate (configured) action against matching packets. Packets that are not filtered by one of these filters and are destined for the 7705 SAR are then scanned by the CSM filter, if configured.
IP exception filters scan all outbound traffic entering a Network Group Encryption (NGE) domain and allow packets that match the exception filter criteria to transit the NGE domain unencrypted.
IP and MAC filter support for SAP and SDP is described in the following sections and is summarized in IP and MAC Filter Support on SAPs and IP and MAC Filter Support on SDPs . Ingress filter override support for routed VPLS on IES and VPRN services is summarized in Routed VPLS Ingress Filter Override Support . IPv4 and IPv6 filter support (ingress and egress) for network interfaces is described in the lists following Routed VPLS Ingress Filter Override Support . MAC filters do not support network interfaces.
Configuring an entity for a filter policy is optional. If a network or service interface is not configured with filter policies, all traffic is allowed on the interface. By default, there are no filters associated with interfaces or services. The filters must be explicitly created and associated. When you create a new filter, you must specify a unique filter ID value for each new filter policy, as well as each new filter entry and associated actions. The filter entries specify the filter matching criteria. See Filter Policy Entries. After creating a filter policy you can also, optionally, assign filters a unique name. Filter IDs or filter names can be used throughout the system to manage filter policies and assign them to interfaces.

IP Filters
IPv4 filters can be applied to the following entities:
network interfaces
ingress and egress network interfaces, affecting incoming traffic from the network link and outgoing traffic to the network link
SAPs
ingress IES management SAPs, affecting incoming node management traffic
ingress pseudowire SAPs (Epipe and Ipipe), affecting incoming user traffic
ingress VPLS SAPs, affecting incoming user traffic
ingress VPRN SAPs and IES SAPs, affecting incoming user traffic
egress VPLS SAPs (Ethernet SAPs only), affecting outgoing user traffic
egress VPRN and IES SAPs, affecting outgoing user traffic
SDPs
ingress VPLS SDPs (spoke and mesh), affecting incoming traffic from the remote end of the service
ingress IES and VPRN interface spoke SDPs, affecting incoming traffic from the remote end of the service
Ingress filters affect only incoming packets regardless of whether the packets need to be forwarded to a downstream router or are destined for the 7705 SAR.
IPv6 filters can be applied to the following entities:
network interfaces
ingress and egress Ethernet network interfaces (with null or dot1q encapsulation)
ingress and egress network interfaces on the 4-port OC3/STM1 Clear Channel Adapter card (with POS encapsulation)
SAPs
ingress IES SAPs
ingress and egress VPLS SAPs
ingress and egress VPRN SAPs
SDPs
ingress VPLS SDPs (spoke and mesh), affecting incoming traffic from the remote end of the service
ingress VPRN interface spoke SDPs, affecting incoming traffic from the remote end of the service
MAC Filters
MAC filters can be applied to the following entities:
SAPs
ingress and egress VPLS SAPs, affecting incoming or outgoing user traffic
SDPs
ingress VPLS SDPs (spoke and mesh), affecting outgoing user traffic
VLAN Filters
VLAN filters can be applied to ring ports at the ingress point on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module. VLAN filters are blocked on all other adapter cards and modules.
CSM Filters
The 7705 SAR supports IPv4 and IPv6 CSM filters. For information on CSM filters, refer to the 7705 SAR System Management Guide, ‟CSM Filters and CSM Security”.
IP Exception Filters
The 7705 SAR supports IPv4 exception filters. For information on IP exception filters, refer to the 7705 SAR Services Guide, ‟Router Encryption Exceptions using ACLs”.
Match List for Filter Policies
The filter match-list ip-prefix-list and ipv6-prefix-list commands define a list of IP prefixes that can be used as match criteria for adapter card IP and IPv6 filters. These commands can also be used for CPM (CSM) filters, IP exception filters, and management access filters.
A match list simplifies the filter policy configuration by allowing multiple prefixes to be listed in a single filter entry instead of creating an entry for each.
The same match list can be used in more than one filter policy. A change in match list content is automatically propagated across all policies that use that list.
To modify any existing IP prefix list, remove any filter that uses it from where it is applied, i.e. a router or service interface, or a SAP or an SDP (spoke and mesh), or for an IP exception in the group-encryption context. For CPM filters, the filter must be shut down.
Similar removal as above is required to modify the filter’s match source and destination IP address values to add, delete, or modify an IP prefix list.
Prefix-exclude
A prefix can be excluded from an IPv4 or IPv6 prefix list with the prefix-exclude command.
For example, when traffic needs to be rate limited to 10.0.0.0/16 with the exception of 10.0.2.0/24, the following options are available.
By applying prefix-exclude, a single IP prefix list is configured with two prefixes:
ip-prefix-list "list-1" create prefix 10.0.0.0/16 prefix-exclude 10.0.2.0/24 exit
Without applying prefix-exclude, all eight included subnets must be manually configured in the IP prefix list:
ip-prefix-list "list-1" create prefix 10.0.0.0/23 prefix 10.0.3.0/24 prefix 10.0.4.0/22 prefix 10.0.8.0/21 prefix 10.0.16.0/20 prefix 10.0.32.0/19 prefix 10.0.64.0/18 prefix 10.0.128.0/17 exit
Manually configuring an IP prefix list is time consuming and error-prone compared to using the prefix-exclude command.
The filter resources, consumed in hardware, are identical between the two configurations.
Configured prefix-exclude prefixes are ignored when no overlapping larger subnet is configured in the prefix list. For example: prefix-exclude 1.1.1.1/24 is ignored if the only included subnet is 10.0.0.0/16.
Network and Service (Access) Interface-based Filtering
IP and MAC filter policies specify either a forward or a drop action for packets, based on information specified in the match criteria. Within each filter policy, you can create entries that define matching criteria.
The same IP filter policy can be assigned to any entity (network interfaces, IP pseudowires, Ethernet pseudowires, VPLS services, VPRN services, and IES services), all of which can be configured on the same adapter card. For example, a filter policy with filter-id defined as filter-5 can be assigned to multiple Ipipe SAPs and, simultaneously, to network interfaces on the same adapter card.
A filter policy assigned to an entity on one adapter card can also be assigned to any entity on another adapter card. For example, a filter policy with filter-id defined as filter-2 can be assigned to an Epipe on an Ethernet adapter card and to a network interface on another Ethernet adapter card.
Only one type of filter (IP or MAC) can be assigned to an interface at a time, and only one filter of that type can be assigned to an interface at a time. The exception is a dual-stack interface (one that supports both IPv4 and IPv6); the interface can have both an IPv4 and an IPv6 filter assigned to it.
Both IP and MAC filter policies are supported per adapter card, and assigning the same filter policy to different entities on a card counts as using one filter policy.
Filter entry matching criteria can be as general or specific as required, but all conditions in the entry must be met in order for the packet to be considered a match and the specified entry action performed. The process stops when the first complete match is found and the action defined in the entry is executed (that is, packets that match the criteria are either dropped or forwarded).
Configuration and assignment of IP and MAC filter policies is similar for network interfaces, IES management SAPs, Ethernet and IP pseudowire SAPs, VPRN and IES interface SAPs and spoke SDPs, and VPLS SAPs and SDPs (spoke and mesh). This guide describes the assignment of filter policies to network interfaces. For detailed information on assigning filters to a service, refer to the 7705 SAR Services Guide; see ‟IP Filters” (under ‟Ethernet VLL (Epipe) Services” and ‟IP Interworking VLL (Ipipe) Services”) for information on assigning IP filter policies to SAPs and spoke SDPs, and see ‟MAC Filters” (under VPLS Features), for information on assigning MAC filter policies to VPLS SAPs and SDPs.
Policy-Based Routing
Traditionally, IP routing is done by making routing decisions based on the destination IP address of the incoming packet. PBR expands the routing decision from one based solely on the destination IP address to include any other IP criteria, such as source IP address, DSCP, or source/destination UDP/TCP port.
Using PBR at the iLER node provides filtering needed to route IP traffic over multiple uplink interfaces or tunnels using IP criteria. For example, a service provider can use PBR to separate high-value traffic (signaling) from user data by examining the source IP address or DSCP bits (or both) of the incoming IP packets and assign a separate transport tunnel to each traffic flow. The transport tunnels can be engineered by using RSVP-TE throughout the entire mobile backhaul network with specific reservation values. The LSP is signaled throughout the network and reserves the needed resources at each node, ensuring the QoS for the high-value traffic.
PBR can also be used to extract packets from the data path and send them to the CSM for debugging or slow path forwarding.
PBR Filtering Based on the DSCP of Incoming Packets illustrates a PBR implementation for VPRN services in an LTE network, and includes CLI command syntax. The 7705 SAR-8 Shelf V2 at the cell site makes routing decisions based on the incoming packet DSCP only, as follows:
BE packets are forwarded to 7750 SR_1 over SDP1
AF11 packets are forwarded to 7750 SR_2 over SDP2
each SDP (SDP1 and SDP2) is signaled throughout the network using RSVP-TE protocol with its own separate TE criteria
PBR is supported at ingress for the following services and interfaces:
IES and VPRN service
SAP
Layer 3 spoke SDP
routed VPLS
router network interface (Global Routing Table (GRT))
PBR is supported on the private IPSec service (VPRN). For more information about IPSec and PBR, see the ‟PBR” section in the 7705 SAR Services Guide.
Multi-field Classification (MFC)
Multi-field classification (MFC) allows untrusted traffic arriving on the access ports of the 7705 SAR to be reclassified and queued according to a forwarding class assigned to the traffic.
Traffic is classified based on IP criteria. Arriving traffic has an ACL (also known as filter policies) applied to it. If the ACL action is forward fc, a match results in the assignment of the corresponding configured Forwarding Class (FC). This FC is used for queuing of the packet through the 7705 SAR. The match can be based on any IP criteria currently supported by the 7705 SAR IP filter policies.
When MFC is configured and a match is made on an arriving packet, the FC is based only on the MFC configuration. The access ingress policy is no longer active for this packet.
Both PBR and MFC are configured under the IP filter configuration and the action of the filter policy can include both PBR (next-hop ip-address) and MFC (fc fc-name).
If MFC is assigned to a Layer 3 spoke-SDP termination interface, MFC classification is based on the traffic’s customer-assigned inner IP packet. The filter policy rules are applied to the IP criteria of the inner packet after the VC label and transport tunnel label have been removed from the packet. Based on the matching criteria, the appropriate FC is assigned to the packet. This functionality allows the customer packet to be marked with the correct DSCP before it egresses the 7705 SAR. This applies only to an untrusted SAP configuration that has a SAP egress QoS policy assigned to it.
MFC is supported at ingress for the following services and interfaces:
IES and VPRN service
SAP
Layer 3 spoke SDP
routed VPLS
router network interface (Global Routing Table (GRT))
VLLs
Epipe
Ipipe
VPLS
SAP
spoke or mesh SDP
Multi-field classification (MFC) is also supported on the private IPSec service (VPRN). MFC functions in the same manner as the VPRN configuration of traditional services.
VLAN-based Filtering
VLAN filter policies specify either a forward or a drop action for packets, based on VLAN ID information specified in the policy match criteria.
Only one VLAN filter is allowed per ring port on the 2-port 10GigE (Ethernet) Adapter card or 2-port 10GigE (Ethernet) module. The same VLAN filter can be applied to both ring ports. Each VLAN filter supports up to 64 matching criteria entries. The filter acts on ingress traffic and the forwarding action sends packets to the other ring port or to the v-port, depending on the packet’s destination.
The number of VLAN filters that can be created depends on the memory available on the 2-port 10GigE (Ethernet) Adapter card or 2-port 10GigE (Ethernet) module.
The 7705 SAR does not support filter logging or statistics collection for VLAN filters.
Filter Policy Entries
Topics in this section include:
A filter policy compares the match criteria specified within a filter entry to packets coming into the system, in the order the entries are numbered in the policy. When a packet matches all the parameters specified in the entry, the system takes the specified action to either drop or forward the packet. If a packet does not match the entry parameters, the packet continues through the filter process and is compared to the next filter entry, and so on.
If the packet does not match any of the entries, the system executes the default action specified in the filter policy, which is to either drop or forward the packet. Each filter policy is assigned a unique filter ID. Each filter policy is defined with:
scope (exclusive or template) (except VLAN filter policies, which always have a template scope)
default action (drop or forward)
description
at least one filter entry
Each filter entry contains:
match criteria
an action
Applying Filter Policies
IPv4 filter policies can be applied at:
network interfaces
ingress and egress of network IP interfaces
SAPs
ingress of Ethernet and IP pseudowire SAPs (Epipe and Ipipe), VPLS SAPs, VPRN SAPs, and IES SAPs
ingress of IES in-band management SAPs
egress of VPRN and IES SAPs
egress of VPLS SAPs (Ethernet only)
SDPs
ingress of VPLS SDPs (spoke and mesh)
ingress of VPRN and IES spoke SDPs
IPv6 filters can be applied at:
network interfaces
ingress and egress of Ethernet network interfaces (with null or dot1q encapsulation)
ingress and egress of network interfaces on the 4-port OC3/STM1 Clear Channel Adapter card (with POS encapsulation)
SAPs
ingress and egress of IES SAPs
ingress and egress of VPRN SAPs
ingress and egress of VPLS SAPs
SDPs
ingress of VPRN spoke SDPs
ingress of VPLS SDPs
MAC filter policies can be applied at the ingress of VPLS SAPs (Ethernet, and ATM on clear channel OC3 adapter cards) and SDPs (spoke and mesh).
VLAN filters can only be applied to ring ports on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module.
Creating and Applying Filter Policies shows the process to create filter policies and apply them to a network interface.
Packet Matching Criteria
IPv4 and IPv6 filter entries can specify one or more matching criteria. However, to support the maximum 256 entries for IPv4 or IPv6 filters, any entry that uses source port (src-port) and/or destination port (dst-port) ranges (lt, gt, or range keywords) as match criteria must be within the first 64 entries.
For IPv6 filters, the combined number of fields for all entries in a filter must not exceed 16 fields (or 256 bits), where a field contains the bit representation of the matching criteria.
All conditions must be met in order for the packet to be considered a match and the specified action performed. The process stops when the first complete match is found and the action defined in the entry is executed (that is, packets that match the criteria are either dropped or forwarded). If no match is found, the default action is to drop the packet.
Matching criteria for IP filters, MAC filters, and VLAN filters are described in IP Filter Policy Criteria, MAC Filter Policy Criteria, and VLAN Filter Policy Criteria, respectively.
IP Filter Matching Criteria
IPv4 and IPv6 filter policies compare the matching criteria to traffic at a network interface. Matching criteria to drop or forward IP traffic are described in IP Filter Policy Criteria.
Criteria |
Description |
---|---|
Protocol identifier/next header |
For IPv4, entering a protocol identifier allows the filter to match the IP protocol. Common protocol numbers include ICMP(1), TCP(6), and UDP(17). For a full list of protocol numbers, see the config>filter>ip-filter>entry>match command in the Filter Command Reference. For IPv6, entering a next header allows the filter to match the first next header following the IPv6 header. |
DSCP name |
Entering a DSP name allows the filter to match DiffServ Code Point (DSCP) names |
Destination IP address and mask |
Entering a destination IP address and mask allows the filter to match destination IP address and mask values (for IPv4) and matching destination IP address and prefix length (for IPv6). The IPv4 address scheme consists of 32 bits expressed in dotted-decimal notation. The IPv6 address scheme consists of 128 bits expressed in colon-hexadecimal format. |
Destination port/range |
Entering a destination port/range allows the filter to match TCP or UDP values |
Fragmentation |
Entering a fragment allows the filter to match the fragmentation state of packets (fragmented or non-fragmented) (not applicable to IPv6) |
ICMP code |
Entering an ICMP code allows the filter to match an ICMP code in the ICMP header |
ICMP type |
Entering an ICMP type allows the filter to match an ICMP type in the ICMP header |
IP option |
Entering an IP option allows the filter to match an option or range of options in the IP header (not applicable to IPv6) |
Multiple IP options |
Entering multiple IP options allows the filter to match the state of multiple option fields in the IP header (true or false) (not applicable to IPv6) |
Option present |
Entering option present allows the filter to match the state of the option field in the IP header (present or absent) (not applicable to IPv6) |
Source IP address and mask |
Entering a source IP address and mask allows the filter to match a source IP address and mask values (for IPv4) or a source IP address and prefix length (for IPv6). The IPv4 address scheme consists of 32 bits expressed in dotted-decimal notation. The IPv6 address scheme consists of 128 bits expressed in colon-hexadecimal format. |
Source port/range |
Entering a source port/range allows the filter to match a TCP or UDP port and range values |
TCP ACK |
Entering TCP ACK allows the filter to match the state of the ACK bit set in the control bits of the TCP header of an IP packet (set or not set) |
TCP SYN |
Entering a TCP SYN allows the filter to match the state of the SYN bit set in the control bits of the TCP header of an IP packet (set or not set) |
MAC Filter Matching Criteria
MAC filter policies compare the matching criteria to traffic at the ingress of a VPLS SAP or SDP (spoke or mesh). Matching criteria to drop or forward MAC traffic are described in MAC Filter Policy Criteria.
Criteria |
Description |
---|---|
Frame type |
Entering the frame type allows the filter to match a specific type of frame format; for example, Ethernet-II only matches Ethernet-II frames |
Source MAC address |
Entering the source MAC address allows the filter to search for a matching source MAC address. Enter the source MAC address in the form xx:xx:xx:xx:xx:xx or xx-xx-xx-xx-xx-xx; for example, 00:dc:98:1d:00:00. |
Destination MAC address |
Entering the destination MAC address allows the filter to search for a matching destination MAC address. Enter the destination MAC address in the form xx:xx:xx:xx:xx:xx or xx-xx-xx-xx-xx-xx; for example, 02:dc:98:1d:00:01. |
Ethertype |
Entering an Ethernet type II Ethertype value allows the value to be used as a filter match criterion. The Ethernet type field is a 2-byte field used to identify the protocol carried by the Ethernet frame. The Ethertype accepts decimal, hex, or binary in the range of 1536 to 65535. |
VLAN Filter Matching Criteria
VLAN filter policies compare the matching criteria to traffic at the ingress of a ring port on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module. Matching criteria to drop or forward traffic are described in VLAN Filter Policy Criteria.
Criteria |
Description |
---|---|
VLAN ID or VLAN range |
Entering a VLAN identifier or range allows the filter to match VLAN ID values |
Untagged |
Selecting untagged allows the filter to match on Ethernet frames with no tag or dot1q header. Having no tag or dot1q header is also referred to as null encapsulation. |
Ordering Filter Entries
When entries are created, they should be arranged sequentially from the most explicit entry to the least explicit. Filter matching ceases when a packet matches an entry. The entry action is performed on the packet, either drop or forward. To be considered a match, the packet must meet all the conditions defined in the entry.
Sufficient free space is required to renumber a filter entry, as there may be multiple sub-entries if IP prefix lists are in use.
The following example displays the number of sub-entries that an entry uses:
*A:SAR8-39-7>config>filter>ip-filter# show filter ip 1 entry 1
===============================================================================
IP Filter
===============================================================================
Filter Id : 1 Applied : No
Scope : Template Def. Action : Drop
Entries : 1
Sub-Entries : 16
Packets are compared to entries in a filter policy in ascending entry ID order. To reorder entries in a filter policy, for example, to reposition entry ID 6 as entry ID 2, use the renum command (renum 6 2).
When a filter policy consists of a single entry, the filter executes actions as follows.
If a packet matches all the entry criteria, the entry’s specified action is performed (drop or forward).
If a packet does not match all of the entry criteria, the policy’s default action is performed (drop or forward).
If a filter policy contains two or more entries, packets are compared in ascending entry ID order (for example, 1, 2, 3 or 10, 20, 30).
Packets are compared with the criteria in the first entry ID.
If a packet matches all the properties defined in the entry, the entry’s specified action is executed.
If a packet does not completely match, the packet continues to the next entry, and then subsequent entries.
If a packet does not completely match any subsequent entries, the default action is performed (drop or forward).
Note: By default, all created filters have a default action of drop (implicit drop). That is, if none of the entries in the filter match the packet, and a default action is not explicitly configured by the user, the packet is dropped.
Filtering Process Example displays an example of several packets forwarded upon matching the filter criteria and several packets traversing through the filter entries and then dropped.
Policy-based Forwarding Over VPLS
The 7705 SAR supports policy-based forwarding over VPLS. PBF enables users to allow ingress traffic but change the regular forwarding that a packet would be subject to. PBF applies to unicast traffic and to broadcast, multicast, and unknown unicast (BMU) traffic. The following PBF actions are supported:
-
SAP
This action forwards incoming traffic onto the specified VPLS SAP and is supported for ingress IPv4/IPv6 and MAC filter policies deployed in the VPLS service. The SAP that the traffic is to egress on must be in the same VPLS service as the incoming interface. If the configured SAP is down, traffic is forwarded according to the forwarding database (FDB).
-
SDP
This action forwards incoming traffic onto the specified VPLS SDP and is supported for ingress IPv4/IPv6 and MAC filter policies deployed in the VPLS service. The SDP that the traffic is to egress on must be in the same VPLS service as the incoming interface. If the configured SDP is down, traffic is forwarded according to the FDB.
Additionally, users can select a default action for a filter policy. The default action is executed on packets if the packets to not match the filter entries. By default, filter policies have a default action set to drop the packet but users can select a default action to forward instead.
PBF Behavior
- If VPLS is attached to an IP interface, the following scenarios apply:
- For traffic destined for r-VPLS interfaces where the Layer 2 destination address of the packets matches the r-VPLS MAC address, Layer 3 forwarding is used and the PBF filter is bypassed.
- If the destination address does not match the r-VPLS MAC address, Layer 2 forwarding to a particular endpoint SAP or SDP and PBF is used (or traffic is flooded if the destination address is not yet known); that is, PBF is performed.
- If the PBF filter entry matches BMU traffic, PBF is performed.
- For mesh SDPs, PBF can be used to direct a packet from the mesh SDP source or ingress to the mesh SDP destination or egress.
- If the filter entry forward destination is an SDP in an endpoint group (spoke-SDP redundancy) and the SDP is inactive, traffic is forwarded according to the FDB.
- Filter statistics:
- The following are scenarios where filter entry statistics are
incremented but the packets may be discarded or forwarded to a different
destination:
- the PBF destination address is down – in this case, the packets are forwarded according to the FDB
- pseudowire redundancy where the PBF destination is the inactive SDP – in this case, packets are forwarded according to the FDB. This is essentially the same action as when the PBF destination address is down.
- packets are forwarded to an r-VPLS interface – when packets cross to the Layer 3 boundary, Layer 2 destinations are no longer available and IP routing is used to forward the packets.
In these cases, the PBF destination status and PBF down behavior are shown in the CLI as part of the filter entry statistics display. This information can be used to assess if the traffic is going to the PBF destination.
- If the packets are dropped before forwarding due to reasons such as source address suppression, mesh SDP-to-mesh SDP forwarding, or unknown destination MAC address discards, the filter statistics only show that there was a match. To see how the packets are ultimately forwarded or dropped, the user can check the SAP or spoke SDP forwarding or discard statistics.
- The following are scenarios where filter entry statistics are
incremented but the packets may be discarded or forwarded to a different
destination:
Filter Log Files
Filter entries can be configured to be written to a filter log file. The log file must exist before any entries can be logged. To create a log file, use the config>filter>log log-id create command. Filter logs can be sent to either memory or an existing syslog server. See Filter Logs for more information.
The 7705 SAR supports filter logging for the following filters:
ingress spoke SDP IPv4, IPv6, or MAC filters (VPLS only)
ingress mesh SDP IPv4, IPv6, or MAC filters (VPLS only)
ingress spoke SDP IPv4 or IPv6 filters (VPRN)
The 7705 SAR does not support filter logging for VLAN filters.
See the 7705 SAR System Management Guide, ‟Syslog”, for information about syslogs.
Configuration Notes
The following information describes the conditions for filter policy implementation.
Creating a filter policy is optional.
Using a filter policy is optional.
A filter policy must be created before it can be applied to a service.
When a filter policy is configured, it must be defined as having either an exclusive scope (for use with one interface), or a template scope (meaning that the filter can be applied to multiple interfaces). VLAN filter policies always have a template scope.
A specific filter must be explicitly associated with a specific interface in order for packets to be matched.
Each filter policy must consist of at least one filter entry. Each entry represents a collection of filter match criteria. When packets enter an ingress port or SAP or SDP, or exit an egress SAP, the packets are compared to the criteria specified within the entry or entries.
When you configure a large (complex) filter, it may take a few seconds to load the filter policy configuration.
The action keyword must be entered for the entry to be active. Any filter entry without the action keyword is considered incomplete and will be inactive.
See the following sections for specific notes on:
IP Filters
Define filter entry packet matching criteria — if a filter policy is created with an entry and an entry action specified, but the packet matching criteria is not defined, then all packets processed through this filter policy entry pass and take the action specified. There are no default parameters defined for matching criteria.
Action — an action keyword must be specified for the entry to be active. Any filter entry without an action keyword specified is considered incomplete and be inactive.
IPv6 Filters
IPv6 packets with extension headers can be filtered with an IPv6 filter, but are subject to some restrictions:
if the packet contains the Hop-by-Hop Options header, slow path extraction occurs and the packet is processed by the CSM's CPM filter (if present); however, the main (fast path) IPv6 filter (service or network filter) filters packets with the Hop-by-Hop Options header
if the authentication header is present in the packet and the target fields for the filter are offset by the presence of the authentication header, the filter does not detect the target header fields and no filter action occurs
No alarms, logs, or statistics are reported in the above cases.
MAC Filters
If a MAC filter policy is created with an entry and entry action specified but the packet matching criteria is not defined, then all packets processed through this filter policy entry pass and take the action specified. There are no default parameters defined for matching criteria.
MAC filters cannot be applied to network interfaces, routable VPRN or IES services.
Some of the MAC match criteria fields are exclusive to each other, based on the type of Ethernet frame. Use MAC Match Criteria Exclusivity Rules to determine the exclusivity of fields.

Only one VLAN filter is allowed per ingress ring port.
-
The same VLAN filter can be applied to both ring ports.
-
The forwarding action sends packets to the other ring port or to the v-port, depending on the packet’s destination.
-
The 7705 SAR does not support filter logging or statistics collection for VLAN filters.
Filter Logs
Summarization logging is the collection and summarization of log messages for one specific log ID within a period of time.
The summarization interval is 100 s.
The filter log can be applied to IP filters, MAC filters, or CPM filters.
For VPLS scenarios, both Layer 2 and Layer 3 are applicable.
Layer 2: source MAC or (optionally) destination MAC
Layer 3: source IPv6 or (optionally) destination IPv6 for Layer 3 filters
Upon activation of a fixed summarization interval, a mini-table with source/destination address and count is created for each filter type (IP, MAC, or CPM).
Every received log packet is examined for the source or destination address.
If the log packet (source/destination address) matches a source/destination address entry in the mini-table (meaning that a packet was received previously), the summary counter of the matching address is incremented.
Configuring Filter Policies with CLI
This section provides information to configure and manage filter policies using the command line interface.
Topics in this section include:
Basic Configuration
The most basic IPv4, IPv6, MAC, and VLAN filter policy must have the following:
a filter ID
scope, either exclusive or template (VLAN filter policies always have a template scope)
default action (drop or forward)
at least one filter entry
specified action, either drop or forward
specified matching criteria
The most basic IP exception filter policy must have the following:
an exception filter policy ID
scope, either exclusive or template
at least one filter entry with a specified matching criteria
Common Configuration Tasks
This section provides a brief overview of the tasks that must be performed for IP filter configuration and provides the CLI commands.
Creating an IPv4 or IPv6 Filter Policy
Configuring and applying filter policies is optional. Each filter policy must have the following:
the filter type specified (IP)
a filter policy ID
a default action (drop or forward)
scope specified, either exclusive or template
at least one filter entry with matching criteria specified
IP Filter Policy
Use the following CLI syntax to create a template IPv4 or IPv6 filter policy:
- CLI Syntax:
config>filter# ip-filter filter-id [create]
description description-string
scope {exclusive | template}
default-action {drop | forward}
- Example:
config>filter# ip-filter
12create
config>filter# description "
IP-filter"
config>filter$ scope
template
- CLI Syntax:
config>filter# ipv6-filter ipv6-filter-id[create]
description description-string
scope {exclusive | template}
default-action {drop | forward}
- Example:
config>filter# ipv6-filter
10create
config>filter# description "ipv6-
filter"
config>filter# scope
template
The following example displays a template filter policy configuration.

A:ALU-7>config>filter#
IP Filter Entry
Within a filter policy, configure filter entries that contain criteria against which ingress, egress, and network traffic is matched. The action specified in the entry determines how the packets are handled, either dropped or forwarded.
Enter a filter entry ID. The system does not dynamically assign a value.
Assign an action, either drop or forward.
Specify matching criteria (see IP Filter Entry Matching Criteria).
The forward next-hop command is used to implement policy-based routing. For details, see Policy-Based Routing. Use the indirect keyword to identify the indirect next-hop router to which packets with matching criteria will be forwarded. The forward fc command is used to implement multi-field classification. For details, see Multi-field Classification (MFC).
Use the following CLI syntax to create an IP filter entry:
- CLI Syntax:
config>filter# ip-filter {filter-id | filter-name}
entry entry-id
description description-string
action [drop]
action forward [next-hop {ip-address | indirect ip-address}] [fc fc-name [priority low | high]]
- Example:
config>filter# ip-filter 11
config>filter>ip-filter# entry
10create
config>filter>ip-filter>entry$ description "

config>filter>ip-filter>entry$ action drop
config>filter>ip-filter>entry# exit
- CLI Syntax:
config>filter# ip-filter {filter-id | filter-name}
entry entry-id
description description-string
action {drop | forward}]

IP Filter Entry for PBR to a System IP or Loopback Address
A PBR rule can be set up to extract packets from the data path and send them to the CSM for debugging or slow path forwarding, by having the next-hop point to a system IP or loopback interface of the 7705 SAR.
The extracted traffic can be rerouted to a final destination based on a RIB lookup on the CSM. The traffic is reinjected to the datapath based on the next-hop address.
PBR CSM Extraction Queue Parameters summarizes the queuing parameters for this functionality. These parameters are for slow path queues created for PBR and are not user-configurable.
Parameter |
Maximum Value |
---|---|
PIR |
1500 kb/s |
CIR |
100 kb/s |
MBS |
20 (non-buffer-chained adapter cards) 80 (buffer-chained adapter cards) |

Configuring a NAT Security Profile
To configure NAT, you must first:
configure a NAT security profile and policy in the config>security context
in the config>security>profile context, specify the timeouts for the tcp/udp/icmp protocols. This step is optional. If you do not configure the profile, a default profile is assigned.
in the config>security>policy context, configure a NAT security policy, and specify the match criteria and the action to be applied to a packet if a match is found
then configure a NAT zone and apply the policy ID to the zone
To configure a NAT security profile, you must create the profile ID. Once created, the profile ID is referenced when you set up a NAT policy.
- CLI Syntax:
config>security# profile profile-id [create]

The following example is for VPLS. A VPRN example includes the interface command (config>service>vprn>interface).
- Example:
config>service# vpls 5000
config>service>vpls# sap 1/5/5
config>service>vpls>sap# ingress filter mac 92
config>service>vpls>sap# egress filter ip 10
config>service>vpls>sap# exit
config>service>vpls# mesh-sdp 15:5000

config>service>vpls# spoke-sdp 15:5001
config>service>vpls>spoke-sdp# ingress filter mac 94
config>service>vpls>spoke-sdp# exit
The following example displays an IP and MAC filter assignment for a VPLS service configuration:

Applying IP Filter Policies to Network Interfaces
IP filter policies can be applied to ingress and egress network IP interfaces.
IPv4 filters are supported on all ingress and egress network interfaces. IPv6 filters are supported on all Ethernet ingress and egress network interfaces (with null or dot1q encapsulation) and on ingress and egress interfaces on the 4-port OC3/STM1 Clear Channel Adapter card (with POS encapsulation).
Filter policies must be created before they can be applied to a network interface. Create filter policies in the config>filter context.
- CLI Syntax:
config>router# interface ip-int-name
egress
filter ip ip-filter-id
filter ipv6 ipv6-filter-id
ingress
filter ip ip-filter-id
filter ipv6 ipv6-filter-id
- Example:
config>router# interface to-104
config>router>if#
ingressconfig>router>if>ingress#
filter ip 10config>router>if# exit
A:ALU-48>config>router# info
#------------------------------------------

port 1/1/1
ingress
filter ip 10
exit
exit
...
#------------------------------------------

Applying VLAN Filter Policies to a Ring Port
VLAN filter policies can be applied to a ring port on the 2-port 10GigE (Ethernet) Adapter card and 2-port 10GigE (Ethernet) module. The filter operates on ingress traffic. Filter policies must be created before they can be applied. Create filter policies in the config>filter context.
- CLI Syntax:
config>port>ethernet# vlan-filter filter-id
- Example:
config>port>ethernet# vlan-filter 2
A:ALU-48>config>port>ethernet# info
#------------------------------------------
...
vlan-filter 2
...
#------------------------------------------
A:ALU-48>config>port>ethernet#
Creating a Match List for Filter Policies
IP filter policies support the use of match lists as a single match criterion. To create a match list, you must:
-
specify the type of match list (for example, an IPv4 address prefix list)
-
define a unique match list name (for example, ‟IPv4PrefixDenylist”)
-
specify at least one valid IPv4 or IPv6 address prefix
Optionally, a description can also be defined.
The following example shows an IPv4 address prefix list configuration and its use in an IPv4 filter policy:
*A:ala-48>config>filter# info
----------------------------------------------
match-list
ip-prefix-list "IPv4PrefixDenylist"
description "default IPv4 prefix denylist"
prefix 10.0.0.0/21
prefix 10.254.0.0/24
exit
exit
ip-filter 10
scope template
filter-name "IPv4PrefixDenylistFilter"
entry 10
match
src-ip ip-prefix-list IPv4PrefixDenylist
exit
action drop
exit
exit
---------------------------------------------
Filter Management Tasks
This section discusses the following filter policy management tasks:
Renumbering Filter Policy Entries
The 7705 SAR exits the matching process when the first match is found and then executes the actions in accordance with the specified action. Because the ordering of entries is important, the numbering sequence can be rearranged. Entries should be numbered from the most explicit to the least explicit.
Use the following CLI syntax to resequence existing IP, MAC, and VLAN filter entries:
- CLI Syntax:
config>filter
ip-filter {filter-id | filter-name}
renum old-entry-idnew-entry-id
- Example:
config>filter>ip-filter# renum 10 15
config>filter>ip-filter# renum 30 40
config>filter>ip-filter# renum 40 1
- CLI Syntax:
config>filter
ipv6-filter {ipv6-filter-id | filter-name}
renum old-entry-idnew-entry-id
- Example:
config>filter>ipv6-filter# renum 10 15
config>filter>ipv6-filter# renum 30 40
config>filter>ipv6-filter# renum 40 1
- CLI Syntax:
config>filter
mac-filter {filter-id | filter-name}
renum old-entry-idnew-entry-id
- Example:
config>filter>mac-filter# renum 10 15
config>filter>mac-filter# renum 30 40
config>filter>mac-filter# renum 40 1
- CLI Syntax:
config>filter
vlan-filter {filter-id | filter-name}
renum old-entry-idnew-entry-id
- Example:
config>filter>vlan-filter# renum 10 15
config>filter>vlan-filter# renum 30 40
config>filter>vlan-filter# renum 40 1
The following output displays the original IPv4 filter entry order followed by the reordered filter entries:

Modifying an IP Filter Policy
To access a specific IPv4 or IPv6 filter, you must specify the filter ID or the filter name (if a filter name is configured). Use the no form of the command to remove the command parameters or return the parameter to the default setting.
- Example:
config>filter>ip-filter# description "New IP filter info"
config>filter>ip-filter# entry 2 create
config>filter>ip-filter>entry# description "new entry"
config>filter>ip-filter>entry# action drop
config>filter>ip-filter>entry# match dst-ip

Modifying a MAC Filter Policy
To access a specific MAC filter, you must specify the filter ID or the filter name (if a filter name is configured). Use the no form of the command to remove the command parameters or return the parameter to the default setting. The example below changes the action to forward.
- Example:
config>filter# mac-filter 90
config>filter>mac-filter# description "Mac_filter90"
config>filter>mac-filter# entry 1
config>filter>mac-filter>entry# description "Mac_entry90_1"

Modifying a VLAN Filter Policy
To access a specific VLAN filter, you must specify the filter ID or the filter name (if a filter name is configured). Use the no form of the command to remove the command parameters or return the parameter to the default setting. The example below adds entry 65535.
- Example:
config>filter# vlan-filter 2
config>filter>vlan-filter# entry 65535 create
config>filter>vlan-filter>entry# description "entry_65535"
config>filter>vlan-filter>entry# action forward

Removing and Deleting a Filter Policy
Before you can delete a filter, you must remove the filter association from the applied ingress and egress SAPs, ingress SDPs, and ingress network interfaces.
You can remove a filter policy and then delete it from the following entities:
Removing a Filter from a Service
To remove an IP or MAC filter from a VPLS SAP or VPLS SDP (spoke or mesh), use the first CLI syntax (below). For a VPRN or IES interface SAP or spoke SDP, use the second CLI syntax:
- CLI Syntax:
config>service# vpls service-id
sap sap-id
egress
no filter ip ip-filter-id
no filter ipv6 ipv6-filter-id
ingress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id | mac mac-filter-id]
spoke-sdp sdp-id:vc-id
ingress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id | mac mac-filter-id]
mesh-sdp sdp-id:vc-id
ingress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id | mac mac-filter-id]
- CLI Syntax:
config>service# vprn service-id
interface ip-int-name
sap sap-id
egress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id ]
ingress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id ]
spoke-sdp sdp-id:vc-id
ingress
no filter [ip ip-filter-id | ipv6 ipv6-filter-id ]
The following example is for VPLS. A VPRN example includes the interface command (config>service>vprn>interface).
- Example:
config>service# vpls 5000
config>service>vpls# sap 1/1/2
config>service>vpls>sap# ingress
config>service>vpls>sap>ingress# no filter ip 232
config>service>vpls>sap>ingress# exit
config>service>vpls>sap# exit
config>service>vpls>spoke-sdp 15:5001
config>service>vpls>spoke-sdp# ingress
config>service>vpls>spoke-sdp>ingress# no filter mac 55
config>service>vpls>spoke-sdp>ingress# exit
config>service>vpls>spoke-sdp# exit
config>service>vpls>mesh-sdp 15:5000
config>service>vpls>mesh-sdp# ingress
config>service>vpls>mesh-sdp>ingress# no filter mac 54
Removing a Filter from a Network Interface
To remove an IPv4 or IPv6 filter from a network interface, enter the following CLI commands:
- CLI Syntax:
config>router# interface ip-int-name
egress
no filter [ip ip-filter-id]
no filter [ipv6 ipv6-filter-id]
ingress
no filter [ip ip-filter-id]
no filter [ipv6 ipv6-filter-id]
- Example:
config>router# interface b11
config>router>if# egress
config>filter>if>egress# no filter ip 12
config>router>if>egress# exit
config>filter>if># ingress
config>filter>if>ingress# no filter ip 2
config>filter>if>ingress# exit
Removing a Filter from a Ring Port
To remove a VLAN filter from a ring port, enter the following CLI command. Including filter-id is optional because only one filter can be applied to a port.
- CLI Syntax:
config>port>ethernet# no vlan-filter [filter-id]
- Example:
config>port>ethernet# no vlan-filter 2
Deleting a Filter
After you have removed the filter from all the network interfaces, SAPs, and SDPs (spoke and/or mesh) where it was applied, use the following CLI syntax to delete the filter:
- CLI Syntax:
config>filter# no ip-filter {filter-id | filter-name}
config>filter# no ipv6-filter {ipv6-filter-id | filter-name}
config>filter# no mac-filter {filter-id | filter-name}
config>filter# no vlan-filter {filter-id | filter-name}
- Example:
config>filter# no ip-filter 2
config>filter# no mac-filter 55

Description
This command creates a text description for a configuration context to help identify the content in the configuration file.
The no form of the command removes any description string from the context.
Default
n/a
Parameters
- description-string
the description character string. Allowed values are any string up to 80 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.
shutdown
Syntax
[no] shutdown
Context
config>filter>log
config>filter>log>summary
Description
The shutdown command administratively disables the 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.
Unlike other commands and parameters where the default state is not indicated in the configuration file, shutdown and no shutdown are always indicated in system-generated configuration files.
The no form of the command puts an entity into the administratively enabled state.
Default
no shutdown
Filter Log Commands
log
Syntax
log log-id [create]
no log log-id
Context
config>filter
Description
This command enables the context to create a filter log policy.
The no form of the command deletes the filter log ID. The log cannot be deleted if there are filter entries configured to write to the log. All filter entry logging associations need to be removed before the log can be deleted.
Default
log 101
Special Cases
- Filter log 101
filter log 101 is the default log and is automatically created by the system. Filter log 101 is always a memory filter log and cannot be changed to a syslog filter log. The log size defaults to 1000 entries. The number of entries and wraparound behavior can be edited.
Parameters
- log-id
the filter log ID destination expressed as a decimal integer
destination
Syntax
destination memory num-entries
destination syslog syslog-id
no destination
Context
config>filter>log
Description
This command configures the destination for filter log entries for the specified filter log ID.
Filter logs can be sent to either memory or an existing syslog server. If the filter log destination is memory, the maximum number of entries in the log must be specified.
The no form of the command deletes the filter log association.
Default
no destination
Parameters
- num-entries
specifies that the destination of the filter log ID is a memory log. The num-entries value is the maximum number of entries in the filter log expressed as a decimal integer.
- syslog-id
specifies that the destination of the filter log ID is a syslog server. The syslog-id parameter is the identifier of the syslog server.
summary
Syntax
summary
Context
config>filter>log
Description
This command enables the context to configure log summarization. These settings apply only if syslog is the log destination.
summary-crit
Syntax
summary-crit dst-addr
summary-crit src-addr
no summary-crit
Context
config>filter>log>summary
Description
This command defines the key of the index of the mini-table. If key information is changed while summary is in the no shutdown state, the filter summary mini-table is flushed and reconfigured with different key information. Log packets received during the reconfiguration time will be handled as if summary was not active.
The no form of the command reverts to the default parameter.
Default
dst-addr
Parameters
- dst-addr
specifies that received log packets are summarized based on the destination IP address
- src-addr
specifies that received log packets are summarized based on the source IP address
wrap-around
Syntax
[no] wrap-around
Context
config>filter>log
Description
This command configures a memory filter log to store log entries until full or to store the most recent log entries (circular buffer).
Specifying wrap-around configures the memory filter log to store the most recent filter log entries (circular buffer). When the log is full, the oldest filter log entries are overwritten with new entries.
The no form of the command configures the memory filter log to accept filter log entries until full. When the memory filter log is full, filter logging for the log filter ID ceases.
Default
wrap-around
Filter Policy Commands
ip-exception
Syntax
ip-exception filter-id [create]
[no] ip-exception {filter-id | filter-name}
Context
config>filter
Description
This command creates a configuration context for an IPv4 exception filter policy. After creating an exception filter ID, you can optionally assign it to a unique name with the filter-name command. The exception filter name can be used instead of the ID for exception configuration commands, show commands, monitor commands, clear commands, and port and interface association commands.
IP exception filter policies specify matching criteria that allow a packet to be an exception to where it is applied. For more information, see the ip-exception command in Router Interface Commands.
The IP exception filter policy is a template that can be applied to multiple router interface group encryption contexts as long as the scope of the policy is configured as template.
Any changes made to the existing policy, using any subcommands, are applied immediately to all network interfaces where the policy is applied.
The no form of the command deletes the IP exception filter policy. An exception filter policy cannot be deleted until it is removed from all network interfaces where it is applied.
Parameters
- filter-id
the IP exception filter policy ID number
- filter-name
the IP exception filter policy name, up to 64 characters in length. The name must already exist within the created IP exceptions.
- create
keyword required when first creating the configuration context. When the context is created, you can navigate into the context without the create keyword.

Syntax
renum old-entry-id new-entry-id
Context
config>filter>ip-exception
config>filter>ip-filter
config>filter>ipv6-filter
config>filter>mac-filter
config>filter>vlan-filter
Description
This command renumbers existing IP, MAC, VLAN, or IP exception filter entries to properly sequence filter entries.
This may be required in some cases since the software exits when the first match is found and executes the actions according to the accompanying action command. This requires that entries be sequenced correctly from most to least explicit.
Parameters
- old-entry-id
the entry number of an existing entry
- new-entry-id
the new entry number to be assigned to the old entry
scope
Syntax
scope {exclusive | template}
no scope
Context
config>filter>ip-exception
config>filter>ip-filter
config>filter>ipv6-filter
config>filter>mac-filter
Description
This command configures the filter policy scope as exclusive or template. If the scope of the policy is template and is applied to one or more network interfaces, the scope cannot be changed.
The no form of the command sets the scope of the policy to the default of template.
Default
template
Parameters
- exclusive
when the scope of a policy is defined as exclusive, the policy can only be applied to a single entity (network port). If an attempt is made to assign the policy to a second entity, an error message results. If the policy is removed from the entity, it becomes available for assignment to another entity.
- template
when the scope of a policy is defined as template, the policy can be applied to multiple network ports
General Filter Entry Commands
entry
Syntax
entry entry-id [create]
no entry entry-id
Context
config>filter>ip-exception
config>filter>ip-filter
config>filter>ipv6-filter
config>filter>mac-filter
config>filter>vlan-filter
Description
This command creates or edits a filter entry. Multiple entries can be created using unique entry-id numbers within the filter. The 7705 SAR implementation exits the filter on the first match found and executes the actions in accordance with the accompanying action command. For this reason, entries must be sequenced correctly, from most to least explicit.
Filter entry IDs support CLI auto-completion. For more information, see the 7705 SAR Basic System Configuration Guide, ‟Entering CLI Commands”.
IPv4 and IPv6 filter entries can specify one or more matching criteria. However, to support the maximum 256 entries for IPv4 or IPv6 filters, any entry that uses source port (src-port) or destination port (dst-port) ranges (lt, gt, or range keywords) as match criteria must be within the first 64 entries. See the dst-port and src-port commands for more information.
For IPv6 filters, the combined number of fields for all entries in a filter must not exceed 16 fields (or 256 bits), where a field contains the bit representation of the matching criteria.
Some adapter cards have limitations on the size of ACLs that can be supported and therefore cannot support the maximum number of IPv6 filter entries. If you attempt to configure more entries than the card can support, the following error log event and SNMP trap are generated:
‟Class MDA Module : runtime event, details: Filter <filter id> ACL_STATUS_IPV6_ FILTER_ENTRIES_EXCEEDED Config Error!”
SNMPv2-MIB:snmpTrapOID.0 : (1.3.6.1.4.1.6527.6.1.2.3.2.1.0.13 (ALU-CHASSIS-MIB:aluEqMdaCriticalRuntimeError)) Syntax: ObjectID ALU-CHASSIS-MIB:aluChassisNotifyMdaRuntimeStatusContext.0 : (runtime event, details: Filter <filter id> ACL_STATUS_IPV6_FILTER_ENTRIES_EXCEEDED Config Error!) Syntax: SNMPv2-TC:DisplayString
where <filter id> is the filter policy ID
An entry may not have any match criteria defined (in which case, everything matches) but must have at least the keyword action for it to be considered complete. Entries without the action keyword are considered incomplete and are rendered inactive.
The no form of the command removes the specified entry from the filter. Entries removed from the filter are immediately removed from all entities to which that filter is applied.
Default
n/a
Parameters
- entry-id
an entry-id uniquely identifies a match criteria and the corresponding action. It is recommended that multiple entries be given entry-ids in staggered increments. This allows users to insert a new entry in an existing policy without requiring renumbering of all the existing entries.
- create
keyword required when first creating the configuration context. When the context is created, you can navigate into the context without the create keyword.

options
Syntax
options {permit ip-option-mask | permit-any}
options ip-option-name [ip-option-name]
Context
config>security>profile>aa>ip
Description
This command controls the inspection of IP options in an IP packet header. The IP options can be specified using either the bit mask value or the name.
The permit command only applies when using bit mask values. It allows packets through the firewall when the IP options on those packets match the bit mask value specified in the ip-option-mask parameter. The ip-option-mask is a flat bit representation of the IP Option Number. The IP Option Copy Bit and IP Option Class Bits are omitted from the ip-option-mask. For example, to permit a packet with the router alert option (which uses IP Option Number 20), bit 20 of the ip-option-mask should be set, which configures the ip-option-mask parameter as 0x00100000. To discard all IP packets with IP options, configure the ip-option-mask parameter as 0x0. To permit any option, configure the ip-option-mask parameter as 0xffffffff or use the permit-any command. When permit-any is configured, the 7705 SAR does not examine IP options and allows all packets through the firewall.
Multiple options can be allowed in a single line of configuration by ‟AND”ing the IP option bit mask values. For example, to permit packets with the router alert, EOOL, and NOP options, configure the ip-option-mask parameter as 0x00100003.
When IP options are specified using ip-option-name, the permit command is implied. Multiple options can be specified by listing multiple names.
Supported IP Options lists the names and bit mask values of the supported IP options.

action
Syntax
action {forward | reject | drop | nat}
Context
config>security>policy>entry
Description
This command specifies what action to take (forward, reject, drop, or NAT) when packets match the entry criteria. An action must be specified in order for the entry to be active. If no action is specified, the entry is inactive.
The nat and forward actions each cause a 6-tuple lookup (source/destination IP address, source/destination port number, protocol, and source zone).
The drop action configures a firewall session on the datapath with the action to drop packets that match the entry criteria. The drop action should be used when an IP connection is carrying a large amount of traffic and CSM processing resources need to be preserved, because the drop action means that packets will not be extracted to the CSM to be rejected. Drop sessions are unidirectional and can be used as a way of blocking traffic from a source issuing a denial of service (DoS) attack.
Entering multiple action statements overwrites previous action statements.
The no form of the command removes the specified action statement.
Default
no action
Parameters
- reject
specifies that packets matching the entry criteria are rejected on the CSM and no firewall session is created on the datapath
- forward
specifies that packets matching the entry criteria are forwarded and a firewall session is created on the datapath
- drop
specifies that a firewall session is created on the datapath with the action to drop packets that match the entry criteria
- nat
specifies that packets matching the entry criteria have NAT applied to them and a NAT session is created on the datapath
action nat
Syntax
action nat [destination ip-address port tcp-udp-port]
Context
config>security>policy>entry
Description
This command specifies the destination IP address and port to which packets that have NAT applied to them are sent.
NAT actions cause a 6-tuple lookup (source/destination IP address, source/destination port number, protocol, and source zone). If there is a match, NAT is applied and the packet is routed based on the datapath session table.
Entering multiple action statements overwrite previous action statements.
The no form of the command removes the specified action statement. An entry is considered incomplete and is rendered inactive if no action is specified.
Default
no action
Parameters
- ip-address
the static NAT (port forwarding) inside destination IP address to be used for port forwarding. When configured, the original packet destination IP address is overwritten with this IP address. This parameter applies only to static destination NAT (port forwarding).
- tcp-udp-port
the static NAT inside port IP number used for port forwarding. When configured, the original packet destination port number is overwritten with this port number. This parameter applies only to static destination NAT (port forwarding).

fwd-direction-only
Syntax
[no] fwd-direction-only
Context
config>security>policy>entry>limit
Description
This command forces a firewall to create a unidirectional session when a packet matches the criteria of the policy entry. In normal operating mode, when a packet matches the criteria and the packet is allowed through, the firewall creates a bidirectional session so that packets traveling in the reverse direction on that session are also allowed through the firewall.
The no form of the command creates a bidirectional firewall session for a matched packet.
Default
