7.5.6 Checking the Configuration
After RSTP protection functions are configured, you can verify that the configurations take
effect.
Prerequisites
All configurations for RSTP protection functions are complete.
Procedure

device.
----End
Example
Run the display stp command to view the status of BPDU protection on a switching device, and
the status of root protection on a specified port. For example:
<Huawei> display stp interface ethernet 2/0/1
