ÑThe entry wonÕt be aged out or deleted on reset.

The buttons at the bottom of the window provide the following functions:
The Delete button is only available when the Filtering Database window is
showing Static entries and one entry in the list is selected. Use the Delete button to
remove an entry from the Static Table; see Deleting a Static Table Entry,
.
The Change button is only available when the Filtering Database window is
showing Static entries and one entry in the list is selected. Use the Change button
to change the selected portÕs receive port/destination ports settings; see
Changing Forwarding and Static Database Entries
,
.
Since the Forwarding table cannot be edited, you must add an entry to the Static
Table in order to change or delete it, as desired. Use the Add to Static Table
button to add a forwarding entry to the static database.
The Aging Time determines how long a Forwarding entry (or a Static entry with
deleteOnTimeout status) is retained before being discarded due to inactivity. Use
the Change Aging Time button to set a new Aging Time; see the following section
for details.
Use the Find button to search the Filtering Database for a speciÞc MAC address;
