Hex Values for Destination Ports
On a bridge with many ports, a Þlter can have more Destination Ports than the
Destination Ports column is able to display. When this occurs, Destination Ports
for that Þlter appear as a hex string that maps to actual port numbers.
If the Destination Ports list is
too long to fit in the column, the
port numbers are represented
by a hex bitmask.
