Enabling Local Proxy ARP

When the Local Proxy ARP option is enabled, a switch responds with its MAC
address to all ARP request on the VLAN. All IP packets are routed through and
forwarded by the switch. The switch prevents broadcast ARP requests from
reaching other ports on the VLAN.
Internet Control Message Protocol (ICMP) redirects will be disabled on
interfaces on which local proxy ARP is enabled.

CLI Commands

To enable local proxy ARP, you must first enter vlan context, for example:
ProCurve(config) vlan 1
Then enter the command to enable local proxy ARP:
ProCurve(vlan-1)ip local-proxy-arp
Syntax: [no] ip local-proxy-arp
Enables the local proxy ARP option. You must be in VLAN
context to execute this command. When enabled on a VLAN,
the switch responds to all ARP requests received on the VLAN
ports with its own hardware address.
The no option disables the local proxy ARP option.
Default: Disabled
Execute the show ip command to see which VLANs have local proxy ARP
enabled.
