The bridge-priority command is used to populate the priority portion of the bridge ID field within outbound BPDUs (the most significant 4 bits of the bridge ID). It is also used as part of the decision process when determining the best BPDU between messages received and sent. When running MSTP, this is the bridge priority used for the CIST.
All values are truncated to multiples of 4096, conforming with IEEE 802.1t and 802.1D-2004.
