Apply an ARP ACL to an Interface or Port-channel

The most recently applied ACL replaces an existing ACL. You do not need to remove an existing ACL.
  1. Access global configuration mode.
    device# configure terminal
  2. Access interface configuration mode.
    device(conf)# interface ethernet 1/2
  3. Access Layer 2 mode.
    device(conf-if-eth-1/2)# switchport
  4. Specify the ACL that you want to apply.
    For more information, see Create an ARP Access Control List.
    device(conf-if-eth-1/2)# ip arp inspection filter ARP_ACL_01
  5. Return to global configuration mode.
    device(conf-if-eth-1/2)# exit
    device(conf)#
The following example summarizes the commands in this procedure.
device# configure terminal
device(conf)# interface ethernet 1/2
device(conf-if-eth-1/2)# switchport
device(conf-if-eth-1/2)# ip arp inspection filter ARP_ACL_01
device(conf-if-eth-1/2)# exit
