Flushing the NDP Cache

It is sometimes necessary to flush the NDP cache when an IP address has changed for a device on the network. As the IP address is linked to a physical address, the IP address can change, but still be associated with the physical address in the NDP Cache. Flushing the NDP Cache allows new information to be gathered and stored.

To configure a specific length of time for an entry to time-out, enter a value in minutes in the NDP Cache entry time-out (minutes) field; see NDP Settings.
