ARP Configuration Examples

The following example:

• Temporarily configures the IP address 10.21.128.1, MAC address 00:00:5e:00:01:01 binding in the ARP table
• Changes the ARP timeout value to 2800 seconds (S-, K-Series)
• Changes the stale entry timeout value to 900 seconds (S-, K-Series)

  System(rw)->set arp 10.21.128.1 00:00:5e:00:01:01 temp
  System(rw)->configure
  System(rw-config)->arp timeout 2800
  System(rw-config)->arp stale-entry-timeout 900
  System(rw-config)->show arp
  FLAGS:    U = Unresolved     S = Static
            L = Local          V = VRRP
            * = Stale          B = Best Guess Interface

The following example enables gratuitous ARP and ARP learning for ARP replies on VLAN 1:

System(rw)->configure
System(rw-config)->interface vlan 1
System(rw-config-intf-vlan.0.1)->ip gratuitous-arp reply
System(rw-config-intf-vlan.0.1)->ip gratuitous-arp-learning reply
System(rw-config-intf-vlan.0.1)->exit
System(rw-config)->

The following example enables proxy ARP for both default and local routes:

System(rw)->configure
System(rw-config)->ip prox
System(rw-config)->interface vlan 1
System(rw-config-intf-vlan.0.1)->ip proxy-arp default-route local
System(rw-config-intf-vlan.0.1)->exit
System(rw-config)->
