TIMEOUT
arp-aging-timeout
Overview
This command sets a timeout period on dynamic ARP entries associated with a
specific interface. If your device stops receiving traffic for the host specified in a
dynamic ARP entry, it deletes the ARP entry from the ARP cache after this timeout
is reached.
Your device times out dynamic ARP entries to ensure that the cache does not fill
with entries for hosts that are no longer active. Static ARP entries are not aged or
automatically deleted.
By default the time limit for dynamic ARP entries is 300 seconds on all interfaces.
The no variant of this command sets the time limit to the default of 300 seconds.
