MSS automatically adds a local entry for a WX switch and dynamic entries 
for addresses learned from traffic received by the switch. You can add the 
following types of entries:

„

Dynamic — Ages out based on the aging timeout.

„

Static — Does not age out but is removed by a software reboot.

„

Permanent — Does not age out and remains in the ARP table 
following a software reboot.

To add an ARP entry, use the following command:

set arp {permanent | static | dynamic} ip-addr mac-addr

To add a static ARP entry that maps IP address 10.10.10.1 to MAC 
address 00:bb:cc:dd:ee:ff, type the following command:

WX1200# set arp static 10.10.10.1 00:bb:cc:dd:ee:ff
success: added arp 10.10.10.1 at 00:bb:cc:dd:ee:ff on VLAN 1

The aging timeout specifies how long a dynamic entry can remain unused 
before the software removes the entry from the ARP table. The default 
aging timeout is 1200 seconds (20 minutes). The aging timeout does not 
affect the local entry, static entries, or permanent entries.

To change the aging timeout, use the following command:

set arp agingtime seconds

You can specify from 0 to 1,000,000 seconds. To disable aging, specify 0.

For example, to disable aging of dynamic ARP entries, type the following 
command:

WX1200# set arp agingtime 0
success: set arp aging time to 0 seconds
