Data Preparation
To configure MSTP parameters, you need the following data.
No. Data
1 Network diameter
2 Hello time, forwarding delay time, maximum aging time, and timeout period for
waiting for BPDUs from the upstream (3 x hello time x time factor)
3 Maximum hop count in an MST region
4 Link type of a port
5 Whether to Rapid transition mechanism
6 Whether to transition to the RSTP mode
7 Maximum number of sent BPDUs
8 Whether a port needs to be configured as an edge port
9 Whether auto recovery needs to be configured for an edge port being shut down
10 Whether a port needs to clear statistics of the spanning tree
11 Whether an edge port needs to be configured as a BPDU filter
9.4.2 Configuring System Parameters
MSTP parameters that may affect network convergence include the network diameter, hello
time, and timeout period for waiting for BPDUs from the upstream (3 x hello time x time factor).
Configure proper MSTP parameters to implement rapid network convergence.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 (Optional) Run:
stp process process-id
The MSTP process view is displayed.
NOTE
This step is needed only when you perform configurations in an MSTP process with a non-zero ID. If you
perform configurations in the MSTP process 0, skip is step.
Step 3 Run:
stp bridge-diameter diameter
The network diameter is configured.
By default, the network diameter is 7.
