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 about proxy ARP, refer to RFC 925, Multi-LAN Address Resolution, and RFC 1027, Using ARP to Implement Transparent Subnet Gateways. Configuration Task List for ARP The following list includes configuration tasks for ARP: • Configure Static ARP Entries (optional) • Enable Proxy ARP (optional) • Clear ARP Cache (optional) • 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 Guide. Configure Static ARP Entries ARP dynamically maps 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 CONFIGURATION mode: Command Syntax arp ip-address mac-address interface Command Mode CONFIGURATION Purpose Configure an IP address and MAC address mapping for an interface. • ip-address: IP address in dotted decimal format (A.B.C.D). • mac-address: MAC address in nnnn.nnnn.nnnn format • interface: enter the interface type slot/port information. These entries do not age and can only be removed manually. To remove a static ARP entry, use the no arp ip-address command syntax. IPv4 Routing | 267
