Using Site Manager
Timing Out Entries in the Address Resolution Cache
IP maintains an address resolution cache on each interface that is configured with
ARP or Proxy Arp. The address resolution cache contains host physical addresses
learned by means of ARP or Proxy ARP.
If you enable the cache timeout feature on this interface, the IP router removes
address resolution cache entries that have not been accessed within a specified
number of seconds. Once an entry is removed, the IP router must use ARP to
reacquire the physical-level address.
A host entry is timed out (deleted) if the IP router sends no traffic destined for that
host within the specified timeout period.
By default, the cache timeout feature is disabled on the interface. You can use the
BCC or Site Manager to enable the feature and to specify a timeout interval (in
seconds).
