Description Factory default
Protocol Version
Specify the version of the STP protocol:

STP: Spanning Tree Protocol.

RSTP: Rapid Spanning Tree Protocol.

MSTP: Multiple Spanning Tree Protocol.
MSTP
Bridge 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.
32768
Forward Delay
The delay used by STP bridges to transit root and designated ports to
forwarding (used in STP compatible mode). The range of valid values is 4 to 30
seconds.
15
Max Age
The maximum time the information transmitted by the root bridge is considered
valid. The range of valid values is 6 to 40 seconds, and Max Age must be <=
(FwdDelay-1)*2.
20
Maximum Hop Count
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 to. The range of valid values is 4 to 30
seconds, and MaxAge must be <= (FwdDelay-1)*2.
20
Transmit Hold Count
The number of BPDU's a bridge port can send per second. When exceeded,
transmission of the next BPDU will be delayed. Valid values are in the range 1 to
10 BPDU's per second.

3.4.3.2 MSTI Mapping
This page allows the user to inspect the current STP MSTI bridge instance priority configurations, and possibly change
them as well.
