Displaying STP Guard Configuration

To display the STP guard configuration, use the following command.

The following example shows 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.
Verify the STP guard configured on port or port-channel interfaces.
