Usage Guidelines

To check whether a peer device is reachable and learn a peer device's MAC address, run the arp send-packet command to configure a local interface to send a unicast ARP request packet that carries the peer device's IP and MAC addresses as the destination addresses.
  • If the peer is reachable, the peer sends an ARP reply packet to the local device. Then, the local device uses information carried in the ARP reply packet to create or update an ARP entry for the peer.
  • If the peer is unreachable, the peer device does not send an ARP reply packet. The local device does not generate an ARP entry.

The ARP entries learned or updated by the local device will be deleted after their aging time expires and can be updated again after the local device receives ARP request packets from the peer device.
