Parameters
| Parameter | Description | Value |
|---|---|---|
| ip-address | Specifies a destination IP address for a unicast ARP request packet to be sent. | This value is in dotted decimal notation. |
| mac-address | Specifies a destination MAC address for a unicast ARP request packet to be sent. | The value is in H-H-H format. H is a hexadecimal number of 4 digits. mac-address cannot be FFFF-FFFF-FFFF. |
| interface interface-type interface-number | Specifies the type and number of an interface for sending out a unicast ARP request packet. | - |
| vid vid | Specifies an outer tag value for a unicast ARP request packet to be sent. | The value is an integer ranging from 1 to 4094. |

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.
