Displaying STP Guard Configuration
To verify the STP guard configured on port or port-channel interfaces, enter the show spanning-tree 0 guard
[interface interface] command.
Figure 52-13 shows an example for an STP network (instance 0) in which:
• Root guard is enabled on a port that is in a root-inconsistent state.
• Loop guard is enabled on a port that is in a listening state.
• BPDU guard is enabled on a port that is shut down (Error Disabled state) after receiving a BPDU.
