Clear Arp-Cache - Supermicro SSE-G2252 User Manual

Command Mode
Global Configuration
Command Usage
• When a ARP entry expires, it is deleted from the cache and an ARP request packet
is sent to re-establish the MAC address.
• The aging time determines how long dynamic entries remain in the cache. If the
timeout is too short, the switch may tie up resources by repeating ARP requests for
addresses recently flushed from the table.
Example
This example sets the ARP cache timeout for 15 minutes (i.e., 900 seconds).
SSE-G2252(config)#arp timeout 900
SSE-G2252(config)#
