Enabling Spanning Tree Protocol Globally

Enable the spanning tree protocol globally; it is not enabled by default.

When you enable STP, all physical, VLAN, and port-channel interfaces that are enabled and in Layer 2 mode are automatically

part of the Spanning Tree topology.

Only one path from any bridge to any other bridge participating in STP is enabled.

Bridges block a redundant path by disabling one of the link ports.
