Clearing ARP Cache

To clear the ARP cache of dynamically learnt ARP information, use the following command.

Clear the ARP caches for all interfaces or for a specific interface by entering the following information. EXEC privilege clear arp-cache [ interface | ip ip-address ] [no-refresh]
  • ip ip-address (OPTIONAL): enter the keyword ip then the IP address of the ARP entry you wish to clear.
  • no-refresh (OPTIONAL): enter the keywords no-refresh to delete the ARP entry from CAM. Or to specify which dynamic ARP entries you want to delete, use this option with interface or ip ip-address .
  • For a port channel interface, enter the keywords port-channel then a number from 1 to 128.
  • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
  • For a VLAN interface, enter the keyword vlan then a number between 1 and 4094.
  • NOTE: Transit traffic may not be forwarded during the period when deleted ARP entries are resolved again and re-installed in CAM. Use this option with extreme caution.
