192.22.73.101).

<subnet mask> Specifies the subnet mask that corresponds to the listed IP address.

Command History

Release 1.1 Command was introduced.

Functional Notes

In general, the principle of proxy-arp allows a router to insert its IP address in the source IP addre ss field of

a packet (if the packet is from a host on one of its subnetworks). This allows host s to reach devices on

other subnetworks without implementing routing or specifying a default gateway.

If proxy-arp is enabled, the AOS will respond to all proxy-arp requests with its specified MAC address and

forward packets accordingly.

Enabling proxy-arp on an interface may introduce unnecessary ARP traf fic on the network.

Usage Examples

The following enables proxy-arp on the loopback interface:

(config)#interface loopback 1

(config-loop 1)#ip proxy-arp
