interfaces dataplane <interface-name> vif <vif-id> ip enable-proxy-arp

Enables proxy ARP on a vif.

set interfaces dataplane interface-name vif vif-id ip enable-proxy-arp
delete interfaces dataplane interface-name vif vif-id ip enable-proxy-arp
show interfaces dataplane interface-name vif vif-id ip enable-proxy-arp

Proxy ARP is not enabled on the vif.

interface-name
The name of a data plane interface. For more information about the supported interface name formats, refer to Data Plane Interface.
vif-id
The ID of a vif. The ID ranges from 1 through 4094.

Configuration mode

interfaces {
     dataplane interface-name {
        vif vif-id {
           ip {
              enable-proxy-arp
           }
        }
     }
}

Use this command to enable proxy Address Resolution Protocol (ARP) on a vif.

Proxy ARP allows a data plane interface to respond with its own media access control (MAC) address to ARP requests for destination IP addresses on subnets that are attached to other interfaces on the system. Subsequent packets sent to those destination IP addresses are forwarded appropriately by the system.

Use the set form of this command to enable proxy ARP on a vif.

Use the delete form of this command to return the system to its default behavior, that is, proxy ARP is not enabled on a data plane interface.

Use the show form of this command to display whether IPv4 packet forwarding is disabled or enabled on a vif.
