ARP Static Configuration
Static ARP entries are permanent in the ARP cache and do not age out like the ARP entries that
are learnt dynamically. Static ARP entries enable the switch to reach the hosts without sending
an ARP broadcast request to the network. Static ARPs are also useful to communicate with
devices that do not respond to ARP requests. Static ARPs can also be configured on some gate-
ways as a protection against malicious ARP Cache corruption and possible DOS attacks.
