Here’s how to translate the hex string to port numbers:1. Translate each hex integer into a four-digit binary value:B 5 4 1 8 0 E 01011 0101 0100 0001 1000 0000 1110 00002. Each “1” in the binary bitmask represents a Destination Port number:B 5 4 1 8 0 E 01011 0101 0100 0001 1000 0000 1110 00001,X,3,4 X,6,X,8 X,10,X,X X,X,X,16 17,X,X,X X,X,X,X 25,26,27,X X,X,X,XStatusIndicates the assigned permanence of the entry:• permanent—The entry won’t be aged out or deleted on reset.• deleteOnReset—The entry will be deleted when the bridge is reset.• deleteOnTimeout—The entry is subject to the aging timer.The buttons at the bottom of the window provide the following functions:The Delete button is only available when the Filtering Database window isshowing Static entries and one entry in the list is selected.
