Hello everyone,

I have a Huawei S12712 switch and want to know how to clear ARP entries. Thank you! 

1. ARP entries of a single VLAN.

2. ARP entry of a single IP address.

3. ARP entries on a single interface.

Dear Rengar,

To make a device update its ARP entries, clear the existing ARP entries on the device.

Procedure
Run the following commands in the user view to clear ARP entries.
1. Run the reset arp dynamic [ ip ip-address [ vpn-instance vpn-instance-name ] ] command to clear dynamic ARP entries.

2. Run the reset arp static command to clear static ARP entries.

You can also run the undo arp static ip-address [ mac-address ] [ vpn-instance vpn-instance-name ], undo arp static ip-address mac-address interface interface-type interface-number[.subinterface-number ], or undo arp static ip-address [ mac-address ] vid vlan-id [ cevid ce-vid ] interface interface-type interface-number[.subinterface-number ] command in the system view to clear static ARP entries.

3. Run the reset arp interface interface-type interface-number[.subinterface-number ] [ ip ip-address ] command to clear ARP entries on a specified interface.

Note:
To delete ARP entries based on a certain IP address, you can run the reset arp dynamic ip ip-address [ vpn-instance vpn-instance-name ] or reset arp interface interface-type interface-number[.subinterface-number ] ip ip-address command.
