FTOS uses two forms of address resolution: ARP and Proxy ARP.

Address Resolution Protocol (ARP) runs over Ethernet and enables endstations to learn the MAC

addresses of neighbors on an IP network. Over time, FTOS creates a forwarding table mapping the MAC

addresses to their corresponding IP address. This table is called the ARP Cache and dynamically learned

addresses are removed after a defined period of time.

For more information on ARP, see RFC 826,

In FTOS, Proxy ARP enables hosts with knowledge of the network to accept and forward packets from

hosts that contain no knowledge of the network. Proxy ARP makes it possible for hosts to be ignorant of

the network, including subnetting.

For more information on Proxy ARP, refer to RFC 925,

ARP to Implement Transparent Subnet Gateways.

Configuration Task List for ARP

The following list includes configuration tasks for ARP:

Configure static ARP entries

Enable Proxy ARP

Clear ARP cache

ARP Learning via Gratuitous ARP

ARP Learning via ARP Request

Configurable ARP Retries

For a complete listing of all ARP-related commands, refer to the FTOS Command LIne Reference.

Configure static ARP entries

ARP dynamically maps the MAC and IP addresses, and while most network host support dynamic

mapping, you can configure an ARP entry (called a static ARP) for the ARP cache.

To configure a static ARP entry, use the following command in the CONFIGURATION mode:

An Ethernet Address Resolution Protocol

Multi-LAN Address Resolution,

and RFC 1027,

IPv4 Routing | 429
