Configuring ARP-Ping MAC

Procedure

1. Run arp-ping mac mac-address { ip-address [ vpn-instance vpn-instance-name ] | interface interface-type interface-number }

   ARP-Ping MAC is enabled to check whether a MAC address is being used by another device.

   There are two possible results after the command is run:

   • If the MAC address is not being used by another device, the command output is as follows:

     [*HUAWEI] arp-ping mac 00e0-fc7d-f201 interface gigabitethernet 0/1/0
       OutInterface: GigabitEthernet0/1/0 MAC[00-E0-FC-7D-F2-01], press CTRL_C to break
       Request timed out
       Request timed out
       Request timed out
     
         ----- ARP-Ping MAC statistics -----

         0 packet(s) received
         MAC[00-E0-FC-7D-F2-01]  not be used

   • If the MAC address is being used by another device, the command output displays the IP address corresponding to this MAC address. The command output is as follows:

     [*HUAWEI] arp-ping mac 00e0-fc7d-f202 interface gigabitethernet 0/1/0
       OutInterface: GigabitEthernet0/1/0 MAC[00-E0-FC-7D-F2-02], press CTRL_C to break
