Address Resolution Protocol configuration

Command: /cfg/l3/arp
[ARP Menu]
Address Resolution Protocol (ARP) is the TCP/IP protocol that resides within the Internet layer. ARP resolves
a physical address from an IP address. ARP queries machines on the local network for their physical
addresses. ARP also maintains IP to physical address pairs in its cache memory. In any IP communication,
the ARP cache is consulted to see if the IP address of the computer or the router is present in the ARP
cache. Then the corresponding physical address is used to send a packet.

Static ARP configuration

Command: /cfg/l3/arp/static
[Static ARP Menu]
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 gateways as a protection
against malicious ARP Cache corruption and possible DOS attacks.
