SMC Networks SMC6724L3 manual 160, Configuring Static ARP Addresses

CONFIGURING THE SWITCH

Web - Click IP, ARP, General. Set the timeout to a suitable value for the ARP cache, enable Proxy ARP for subnetworks that do not have routing or a default gateway, and click Apply.

CLI - This example sets the ARP cache timeout for 15 minutes (i.e., 900 seconds), and enables Proxy ARP for VLAN 3.

Console(config)#arp-timeout 900	4-223
Console(config)#interface vlan 3	4-119
Console(config-if)#ip proxy-arp	4-224
Console(config-if)#

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.)
