Configuring a TCAM ACL Customization Group

Configuring a TCAM ACL Customization Group

Prerequisites

A TCAM ACL customization profile has been created.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run system tcam acl template template-name

    The view of an existing TCAM ACL customization profile is displayed.

  3. Run group group-name [ precedence precedence-value ]

    A TCAM ACL customization group is created and its view is displayed.

  4. Configure a matching rule in the TCAM ACL customization group.

    Matching Rule

    Command

    Configure a matching rule based on Ethernet information.

    match ethernet { 8021p | destination-mac | ethertype | inner-8021p | inner-vlan | source-mac | vlan } *

    Configure a matching rule based on IPv4 packet information.

    match ip { destination-ip | source-ip | fragment | protocol | tos | ttl } *

    Configure a matching rule based on IPv6 packet information.

    match ipv6 { destination-ip | destination-ip-high | source-ip | source-ip-high | protocol | tos | ttl } *

    Configure a matching rule based on TCP packet information.

    match tcp { tcp-flag | destination-port | source-port | l4port-range } *

    Configure a matching rule based on UDP packet information.

    match udp { destination-port | source-port | l4port-range } *

    Configure a matching rule based on ICMP packet information.

    match icmp icmp-type

    Configure a matching rule based on IGMP packet information.

    match igmp igmp-type

    Configure a matching rule based on MPLS packet information.

    match mpls { bos | forward-label-action | exp } *

    Configure a matching rule based on the forwarding status.

    match forwarding { destination-interface | source-interface | l2sub-interface | bridge-domain | bd-virtual-interface | vlan | vlanif | source-trunk | vrf | vsi } *

    NOTE:

    The CE6870EI and CE6875EI do not support the vlan and vlanif parameters.

    Only the CE6850HI, CE6850U-HI, CE6851HI, CE6855HI, CE6856HI, CE6857EI, CE6860EI, CE6865EI, CE7850EI, CE7855EI, CE8850EI, CE8860EI, CE8861EI, and CE8868EI support the bridge-domain and bd-virtual-interface parameters.

    The CE6880EI, CE6875EI, CE6870EI, and CE5880EI do not support the source-trunk parameter.

    Configure a matching rule based on user-defined packets.

    match { udf { ipv4-head | inner-ipv4-head | l2-head | l4-head } [ negative ] { head-length offset-length } }&<1-8>

  5. Run action { car | deny | forwarding-modify | ioam | mac-address-learning-disable | mirror | redirect { eth-trunk | flow | interface | nexthop | observe-port } * | remark { 8021p | dscp | exp | local-precedence | vlan | tos } * | share-car | snoop | statistics | trap } *

    An action in the TCAM ACL customization group is configured.

    NOTE:

    Only the CE6865EI, CE8861EI, CE8868EI support ioam parameter.

  6. Run commit

    The configuration is committed.
