IP Routing Features
Configuring IP Parameters for Routing Switches
N o t e s 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.
ProCurve(vlan-1)# show ip
