Displaying STP Guard Configuration
To verify the STP guard configured on RSTP port or port-channel interfaces, enter the show spanning-tree
rstp guard command. Refer to the Spanning Tree Protocol chapter for information on how to configure and
use the STP root guard, loop guard, and BPDU guard features.
The following example shows an example for an RSTP 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 forwarding state.
• BPDU guard is enabled on a port that is in a blocking state.
