Enable ARP Proxy

About this task

Configure an ARP proxy to allow the platform to answer a local ARP request for a remote destination. ARP proxy is disabled by default.

Procedure

  1. Enter Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Enable ARP proxy on the device:

    ip arp-proxy enable

    Use the no operator to disable ARP proxy: no ip arp-proxy [enable]

Example

Enable ARP proxy on VLAN 200:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#interface vlan 200
Switch:1(config-if)#ip arp-proxy enable
