SROS Command Line Interface Reference Guide
ip proxy-arp <ip address> <subnet mask>
Use the ip proxy-arp command to enable proxy Address Resolution Protocol (ARP) on the interface. Use
the no form of this command to disable this feature.
Syntax Description
<ip address>
<subnet mask>
Default Values
By default, ip proxy arp is enabled.
Functional Notes
In general, the principle of proxy ARP allows a router to insert its IP address in the source IP address field
of a packet (if the packet is from a host on one of its subnetworks). This allows hosts to reach devices on
other subnetworks without implementing routing or specifying a default gateway.
If proxy ARP is enabled, the SROS will respond to all arp requests with its specified MAC address and
forward packets accordingly.
Enabling proxy ARP on an interface may introduce unnecessary ARP traffic on the network.
Usage Examples
The following enables proxy ARP on the Ethernet interface:
ProCurve(config)#interface ethernet 0/1
ProCurve(config-eth 0/1)#ip proxy-arp
5991-2114
Defines the proxy ARP IP address in dotted decimal notation (for example:
192.168.73.101).
Specifies the subnet mask that corresponds to the listed IP address.
