Default Setting
Disabled
Command Mode
Interface Configuration (VLAN)
Command Usage
• Proxy ARP allows a non-routing device to determine the MAC address of a host on another
subnet or network.
• End stations that require Proxy ARP must view the entire network as a single network. These
nodes must therefore use a smaller subnet mask than that used by the router or other relevant
network devices.
• Extensive use of Proxy ARP can degrade router performance because it may lead to increased
ARP traffic and increased search time for larger ARP address tables.
Example
Console(config)#interface vlan 3
Console(config-if)#ip proxy-arp
Console(config-if)#
