8.6.5 Checking the Configuration
After MSTP parameters are configured for the interoperability between Huawei devices and
non-Huawei devices, you can verify the configurations.
Prerequisites
All the configurations for the interoperability between Huawei devices and non-Huawei devices
are complete.
Procedure
l
Run the
display stp
[

----End
Example
Run the
display stp
command to view the spanning-tree working mode, BPDU format and
MSTP protocol packet format, and configuration for the digest snooping function. For example:
<Huawei>
display stp instance 0 interface ethernet 2/0/1
