ip proxy-arp

Enables proxy ARP on an interface.

Synopsis ip proxy-arp

no ip proxy-arp

Operands None

Defaults Proxy ARP is disabled.

Command Modes Interface subtype configuration mode

Description Use this command to enable proxy ARP on a specific interface. Proxy ARP allows a Brocade device

to answer ARP requests from devices on one network on behalf of devices in another network.

Because ARP requests are MAC-layer broadcasts, they reach only the devices that are directly

connected to the sender of the ARP request. Therefore, ARP requests do not cross routers.

Usage Guidelines Enter no ip proxy-arp to disable proxy ARP on a specific interface.

Examples To enable proxy ARP on a specific 10-gigabit Ethernet interface:

switch(config)# interface tengigabitethernet 178/0/9

switch(conf-if-te-178/0/9)# ip proxy-arp

To disable proxy ARP on a specific 40-gigabit Ethernet interface:

switch(config)# interface fortygigabitethernet 1/3/1

switch(conf-if-fo-1/3/1)# no ip proxy-arp
