The set protocols spanning-tree mstp msti bridge-priority command sets the bridge priority for an MSTI of the switching device.
set protocols spanning-tree mstp msti <instance-id> bridge-priority <bridge-priority>
Specifies the MST instance. The value is an integer that ranges from 1 to 16. Each process supports a maximum of 16 instances.
Specifies the bridge priority of the switching device for an MSTI.
The value is an integer ranges from 0 to 61440. The default value is 32768.
Priorities of switching devices are an important factor to calculate a spanning tree and determine the selection of the root bridge. The smaller the priority value of a switching device is, the higher the possibility that the switching device is selected as the root bridge.
- Set the bridge priority of the switching device to 55 for MSTI 5.
