Switching and Routing > Clearing the ARP Cache

Clearing the ARP Cache
To remove all data from the ARP cache, enter the following commad:
ServerIron# clear arp
To clear all ARP entries for port 2 on the module in slot 3, enter commands such as the following:
ServerIron# clear arp ethernet 3/2
Syntax: clear arp [ethernet <num> | mac-address <xxxx.xxxx.xxxx> [<mask>] | <ip-addr> [<ip-mask>]]
Specify the MAC address mask as “f”s and “0”s, where “f”s are significant bits. Specify IP address masks in standard decimal mask format (for example, 255.255.0.0).
NOTE: The clear arp command clears learned ARP entries but does not remove any static ARP entries.
