Removing an incorrect ARP entry
Suppose that a misconfigured system has an incorrect IP
address, causing bad ARP information to be installed on
another node. SNMP can be used to remove the offending
address remotely. This can be very useful if the node in
question has a very long timeout on the ARP cache, or some
important connection is being established with the wrong host.
The following example shows how the administrator might proceed.
