Huawei quidway s7700 - Enabling MSTP; Checking the Configuration

The value range of the priority is from 0 to 240, with the step 16. That is, the port priority can
be 0, 16, or 32.
----End
9.2.7 Enabling MSTP
After basic MSTP functions are configured on a switching device, enabling the MSTP function
is required so that MSTP can work properly.
Context
After MSTP is enabled on a ring network, MSTP immediately calculates spanning trees on the
network. Configurations on the switching device, such as, the switching device priority and port
priority, will affect spanning tree calculation. Any change of the configurations may cause
network flapping. Therefore, to ensure rapid and stable spanning tree calculation, perform basic
configurations on the switching device and its ports and enable MSTP.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
stp enable
MSTP is enabled on the switching device.
By default, the MSTP function is enabled on a S7700.
----End
9.2.8 Checking the Configuration
After basic MSTP functions are configured, verify that the configurations take effect.
Prerequisite
All configurations of basic MSTP functions are complete.
Procedure
l Run the display stp [ instance instance-id ][ interface { interface-type interface-
number } ] [ brief ] command to view spanning-tree status and statistics.
l Run the display stp region-configuration command to view configurations of activated
MST regions.
l Run the display stp region-configuration [ digest ] command to view the digest
configurations of activated MST regions.
