Figure 33-4. Spanning Tree Enabled Globally To view the STP configuration and the interfaces that are participating in STP, use the show spanning-tree 0 command from EXEC privilege mode. If a physical interface is part of a port channel, only the port channel is listed in the command output (Figure 33-5).
