Adding a Static Entry in the ARP Cache

You can add a static (permanent) entry in the ARP cache using the arp command.

You can specify the ipAddress, interfaceType and interfaceSpecifier (as indicated in Interface Types and Specifiers in JunosE Command Reference Guide ), and an optional MAC address.

To add a static entry in the ARP cache:

• Issue the arp command in Global Configuration mode.
  host1(config)#arp 192.56.20.1 gig 2/0 0090.1a00.0170

  Note: You can issue this command only for Fast Ethernet interfaces, Gigabit Ethernet interfaces, 10-Gigabit Ethernet interfaces, and bridged Ethernet interfaces configured over ATM 1483.

  Use the no version to remove an entry from the ARP cache.
