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.
To flush an entry in the NDP Cache table
- Mouse-over the NDP Cache entry and click the Flush icon on the right side.
To flush one or more entries in the NDP Cache table
- Select the checkbox(es) of one or more entries to be flushed.
- Mouse-over an NDP Cache entry and click Flush.
To flush all the entries in the NDP Cache table
- Select the top left checkbox in the NDP Cache table header. All NDP Cache entries are selected.
- Mouse-over an entry and click Flush or Flush All.
