Configure Tag Addition

Follow this procedure to add a VLAN tag to tagged or non-tagged packets.

About this task

Tag addition is performed in the first L2 header.

Procedure

  1. Enter the Config mode.
    device(config)# 
  2. Configure an ACL of type IPv4, IPv6, or MAC and any actions.
    device(config)# ip access-list acl5-ipv4
    device(config-ip-acl)# seq 10 permit ip any any count
    The specified ACL and configured actions will be bound to a listener policy.
  3. Create the listener policy, including any action subcommands for the policy.
    Note

    Note

    A listener policy supports only one IPv4 ACL, IPv6 ACL, or MAC ACL. The VLAN id tag value ranges from 1 to 4095.
    device(config)# listener-policy lp-2 32
    device(config-listener-policy)# match ip access-list acl5-ipv4
    device(config-listener-policy)# vlan id
    device(config-listener-policy)# description "ipv4 tag add lp"
  4. Configure an egress policy, and bind the listener policy, specifying any additional egress actions.
    Note

    Note

    An egress can be associated with only one listener policy.
    device(config)# egress e2
    device(config-egress)# set listener-policy lp-2 32
    device(config-egress)# description DirectTool
    device(config-egress)# precedence 1 interface ethernet 2/14
  5. Configure an egress group and associate it with the egress policy.
    device(config)# egress-group eg_1 
    device(config-egress-group)# description e-group_1
    device(config-egress-group)# set egress e2
  6. Configure the route map and set any other parameters, such as forwarding actions, match ip access list, and the egress-group.
    Note

    Note

    A route-map policy supports only one match-ACL per layer.
    device(config)# route-map R1 10
    device(config-route-map)# match ip access-list acl5-ipv4
    device(config-route-map)# set egress-group eg_1
    device(config-route-map)# forward-action permit
  7. Configure an ingress group and associate a route map.
    Note

    Note

    An ingress group can be associated with only one route map.
    device(config)# ingress-group TAP_TRAFFIC
    device(config-ingress-group)# set route-map R1 10
  8. Configure the interface port and channel for ingress traffic.
    Note

    Note

    In the following example, traffic is coming in on slot/port number 2/3.
    interface ethernet 2/3
    description From_TAP
    set ingress-group TAP_TRAFFIC
    no shutdown
  9. Configure the interface port and channel for egress traffic.
    Note

    Note

    In the following example, traffic is leaving on slot/port number 2/14.
    interface ethernet 2/14
    speed 100000
    description To_Tool
    no shutdown
