Usage Guidelines
•
This command is an explicit Spanning Tree command that only applies to the specified VLAN instance
regardless of which operating mode (flat or 1x1) is active on the switch.
•
If the switch is running in flat mode when this command is used, the specified protocol is not active for
the specified VLAN instance until the operating mode for the switch is changed to 1x1.
•
Note that when a configuration snapshot is taken of the switch, all Spanning Tree commands are saved
in their explicit format.
Examples
-> bridge 1x1 2 protocol stp
