CLI - This example sets the ARP cache timeout for 15 minutes (i.e., 900
seconds), and enables Proxy ARP for VLAN 3.
Configuring Static ARP Addresses
For devices that do not respond to ARP requests, traffic will be dropped
because the IP address cannot be mapped to a physical address. If this
occurs, you can manually map an IP address to the corresponding physical
address in the ARP.
Command Usage
• You can define up to 128 static entries in the ARP cache.
• Static entries will not be aged out or deleted when power is reset. You
can only remove a static entry via the configuration interface.
Command Attributes
• IP Address – IP address statically mapped to a physical MAC address.
(Valid IP addresses consist of four numbers, 0 to 255, separated by
periods.)
• MAC Address – MAC address statically mapped to the corresponding
IP address. (Valid MAC addresses are hexadecimal numbers in the
format: xx-xx-xx-xx-xx-xx.)
• Entry Count – The number of static entries in the ARP cache.
