Version 8.3.7.0 8.1.1.0 7.6.1.0 7.5.1.0 pre-6.2.1.1 Description Introduced on the S4810. Introduced on the E-Series. Introduced on the S-Series. Introduced on the C-Series. Introduced on the E-Series. clear arp-cache Clear the dynamic ARP entries from a specific interface or optionally delete (no-refresh) ARP entries from the content addressable memory (CAM). Syntax Parameters clear arp-cache [vrf vrf-name | interface | ip ip-address] [no-refresh] vrf vrf-name interface (OPTIONAL) Enter the keyword vrf and then the name of the VRF to clear the ARP cache corresponding to that VRF. (OPTIONAL) Enter the following keywords and the interface information: • For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information. • For the Management interface on the stack-unit, enter the keyword ManagementEthernet then the slot/port information. • For a port channel interface, enter the keywords port-channel then a number. • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094. ip ip-address no-refresh (OPTIONAL) Enter the keyword ip then the IP address of the ARP entry you wish to clear. (OPTIONAL) Enter the keywords no-refresh to delete the ARP entry from CAM. Or use this option with interface or ip ip-address to specify which dynamic ARP entries you want to delete. 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.
