Deleting A Permanent Entry From The Arp Table; Clearing A Dynamic Entry From The Arp Table - Alcatel OmniSwitch 6624 Network Configuration Manual

IP Forwarding

Deleting a Permanent Entry from the ARP Table

Permanent entries do not age out of the ARP table. Use the no arp command to delete a permanent entry
from the ARP table. When deleting an ARP entry, you only need to enter the IP address. For example to
delete an entry for IP address 171.11.1.1, you would enter:
-> no arp 171.11.1.1
Use the show arp command to display the ARP table and verify that the entry was deleted.
Note. You can also use the no arp command to delete a dynamic entry from the table.

Clearing a Dynamic Entry from the ARP Table

Dynamic entries can be cleared using the
entries. Permanent entries must be cleared using the no arp command.
Use the show arp command to display the table and verify that the table was cleared.
Note. Dynamic entries remain in the ARP table until they time out. If the switch does not receive data
from a host for this user-specified time, the entry is removed from the table. If another packet is received
from this host, the switch goes through the discovery process again to add the entry to the table. The
switch uses the MAC Address table timeout value as the ARP timeout value. Use the
aging-time command to set the timeout value.
