The page includes the following fields:

• System Priority

Specifies the bridge priority value. When switches or bridges are running STP,

each is assigned a priority. After exchanging BPDUs, the switch with the lowest

priority value becomes the Root Bridge. The bridge priority value is provided in

increments of 4096 (4K increments). For example, 0, 4096, 8192, etc.

The default value is 32768.

Compatible – Classis STP (802.1d): Provides a single path between end

stations, avoiding and eliminating loops.
