The Page includes the following fields:
Object Description
• Priority
Controls the bridge priority. Lower numeric values have better priority. The bridge
priority plus the MSTI instance number, concatenated with the 6-byte MAC
address of the switch forms a Bridge Identifier.
For MSTP operation, this is the priority of the CIST. Otherwise, this is the priority
of the STP/RSTP bridge.
• Max Hops
This defines the initial value of remaining Hops for MSTI information generated at
the boundary of an MSTI region. It defines how many bridges a root bridge can
distribute its BPDU information. Valid values are in the range 1 to 40 hops.
• Forward Delay
The delay used by STP Bridges to transition Root and Designated Ports to
Forwarding (used in STP compatible mode). Valid values are in the range 4 to 30
