arp [vrf vrf-name]ip-address hardware-address [ interface interface-id]

•
vrf-name—The name of the VRF with which the ARP entry is to be
associated. If no VRF is specified, the ARP entry is associated with the
global ARP table.
•
ip-address — IP address of a device on a subnet attached to an existing
routing interface.
•
hardware-address — A unicast MAC address for that device.
•
interface-id—An optional IP unnumbered (VLAN) interface identifier.

User Guidelines
The VRF identified in the parameter must have been previously created or an
error is returned.
Only IPv4 addresses are supported with the vrf parameter.
The vrf parameter is only available on the N3000/N3100/N4000 switches.
The interface identifier is the identifier of the unnumbered interface, not the
loopback interface from which the IP address is borrowed.
When adding a static ARP entry with an unnumbered interface, the ip
address must match the mask of the unnumbered interface.
A static ARP entry is only installed if the IP address matches one of the local
subnets. In case of unnumbered interfaces, static ARP entries created for the
unnumbered-peer do not match any of the local subnets and cannot be
resolved to an interface. By specifying the interface explicitly in the static
ARP command, static ARP entries for unnumbered-peers can be configured.
