Parameter Description
Bridge Priority Synopsis: { 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864,
40960, 45056, 49152, 53248, 57344, 61440 }
Default: 32768
Bridge Priority provides a way to control the topology of the STP connected network.
The desired Root and Designated bridges can be configured for a particular topology.
The bridge with the lowest priority will become root. In the event of a failure of the root
bridge, the bridge with the next lowest priority will then become root. Designated bridges
that (for redundancy purposes) service a common LAN also use priority to determine
which bridge is active. In this way careful selection of Bridge Priorities can establish the
path of traffic flows in normal and abnormal conditions.
4. Click Apply.
