Spanning Tree Commands
This section includes commands that configure the Spanning Tree Algorithm (STA) globally for the
switch, and commands that configure STA for the selected interface.
TABLE 76 Spanning Tree Commands
Command Function Mode
spanning-tree Enables the spanning tree protocol GC
spanning-tree
