Displaying STP Guard Configuration
To verify the STP guard configured on port or port-channel interfaces, use the show spanning-tree 0 guard
[interface interface]
command.
Figure 33-13 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.
• BPDU guard is enabled on a port that is shut down (Error Disabled state) after receiving a BPDU.
• Bpdu filter is disabled on the ports.
