STP Priority
Sets the bridge priority for the spanning tree algorithm.
Default: 32768
Options
Skip this field if you have not enabled the spanning tree algorithm.
If you have enabled the algorithm, STP Priority supplies the most-significant
16-bits of the unique 64-bit bridge identifier used by the algorithm to identify
the root bridge (the bridge with the best priority). The smaller this value, the
more likely it is that the bridge will be the root. Choose one of the following
options:
11023
32047
74095
15 8191
31 16383
63 32767
127 32768 (default)
255 32769
511 65535
When assigning values to the spanning tree parameters (Hello Time, Max Age,
and Forward Delay), you might want to use the values listed in table 6-1 (page 6-
19.
Table Age Interval
Sets a time interval, in minutes, for aging the learning bridge entries in the
forwarding table.
Default: 60
Disable: 0
Options
0, 5, 30, 60 (default), 120, 180, 240, 300
The Table Age Interval controls how frequently the learning bridge entries are
checked for removal from the bridge forwarding table. Each time a frame is
forwarded to a station, its entry in this table is time-stamped. If the entry is not
accessed for twice this interval, the entry is removed from the table. A value of
zero disables the timer and aging is no longer performed.
Note: If the network contains a high number of end stations, a shorter duration
can prevent the forwarding table from being filled.
