seconds), and enables Proxy ARP for VLAN 3.
6.20.5.3 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, an IP
address can be manually mapped to the corresponding physical address in the
ARP.
Command Usage
• Up to 128 static entries can be defined in the ARP cache.
• Static entries will not be aged out or deleted when power is reset. A
static entry can only be removed through the configuration interface.
Console(config)#arp-timeout 900
