Common ARP Operations : Updating ARP Entries

Latest reply: Jun 28, 2016 01:35:13 1550 1 0 0 0

Before updating ARP entries, clear ARP entries on the device so that the device will relearn the entries.


After ARP entries are cleared, mappings between IP addresses and MAC addresses are deleted. As a result, users may not access specified nodes. Exercise caution when you clear ARP entries.

# Clear all ARP entries on the device.

<HUAWEI> reset arp all

# Clear the dynamic ARP entries with the IP address on the device.

<HUAWEI> reset arp dynamic ip //If the IP address is not specified, all dynamic ARP entries are deleted from the device.

# Clear all static ARP entries on the device.

<HUAWEI> reset arp staticWarning: This operation will reset all static ARP entries, and clear the configurations of all static ARP, continue?[Y/N]:y

# Clear the static ARP entries with the IP address, MAC address 0023-0045-0067, and outbound interface GE1/0/1 on the device.

<HUAWEI> system-view

# Clear the ARP entries learned from VLANIF 100 with the IP address on the device.
