Switch STP Inspection

Procedure

1.     Login the OOB Switch;

2.     Run the command “display stp global” to show STP global configuration

3.     Run the   command “display stp interface GigabitEthernet   0/0/x” to show interface STP configuration.

4.     Run the   command “display stp brief” to   check the stp status:

Expected Results

Results

Show the   STP global configuration, STP mode is ‘MSTP’, BPDU-Protection is ‘Enable’;

Show the   access interface STP configuration, Port   role is ‘disabled’,   BPDU-Protection is ‘Enable’

STP state   for all the ports should be FORWARDING.
