IP Router Configuration 
7705 SAR OS Router Configuration Guide 119
The command returns an error if the interface is already associated with another port or the system. In 
this case, the association must be deleted before the command is reattempted. 
The port name consists of the port-id (for T1/E1 interfaces and Ethernet interfaces) and an optional 
encapsulation value (for Ethernet interfaces). The port name can also be the bundle-id used for the 
multilink bundle (PPP or IMA). Refer to the 7705 SAR OS Interface Configuration Guide for 
information on configuring ports.
The no form of the command deletes the association with the port. The no form of this command can 
only be performed when the interface is administratively down.
Default no port

Context config>router>interface
Description This command enables proxy ARP on the interface and specifies an existing policy statement that 
controls the flow of routing information by analyzing match and action criteria. The policy statement 
is configured in the config>router>policy-options context (see Route Policy Options in the Route 
Policy Command Reference section). When proxy ARP is enabled, the 7705 SAR responds to ARP 
requests on behalf of another device.
Default no proxy-arp-policy
