Object Description

riority
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 6 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 seconds
-Default: 15
-Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]
