Configuring Static ARP Entries


You can create static ARP table entries, which are explicit mappings between IP addresses and MAC addresses.

  • To configure a static ARP entry:

    [edit interfaces interface-name unit logical-unit-number family inet address address]

    user@switch# set arp ip-address (mac | multicast-mac) mac-address

The IP address that you specify must be part of the subnet defined in the enclosing address statement.

To associate a multicast MAC address with a unicast IP address, use the multicast-mac statement.

Specify the MAC address as 6 hexadecimal bytes in one of the following formats: nnnn.nnnn.nnnn or nn:nn:nn:nn:nn:nn; for example, 0011.2233.4455 or 00:11:22:33:44:55.
