Disable Spanning Tree Configuration
This chapter describes disabling spanning tree operation on a per Multiple Spanning Tree Instance (MSTI) basis.
Topology
Disable Spanning Tree Topology
Note: Run the switchport command on each port to change to Layer-2 mode.
Disabling MSTP Configuration
Bridge 1
Disabling MSTP per instance
 
Bridge1(config-mst)#no bridge 1 instance 2
Disable spanning tree for MSTP on instance 2
Bridge1(config-mst)#no bridge 1 instance 3
Disable spanning tree for MSTP on instance 3
Disabling MSTP globally
 
Bridge1(config)#no bridge 1 multiple-spanning-tree enable bridge-forward
Disable spanning tree globally for MSTP and keeping the ports in forwarding state.
Disabling MSTP per port
 
Bridge1(config)#interface ge2
Enter interface mode for ge2.
Bridge1(config-if)#bridge-group 1 spanning-tree disable
Disable spanning tree per port for MSTP and put port on forwarding state. This command disables any type of STP on the port.
 
Bridge 2
Disabling MSTP per instance
 
Bridge2(config-mst)#no bridge 1 instance 2
Disable spanning tree for MSTP on instance 2
Bridge2(config-mst)#no bridge 1 instance 3
Disable spanning tree for MSTP on instance 3
Disabling MSTP globally
 
Bridge2(config)#no bridge 1 multiple-spanning-tree enable bridge-forward
Disable spanning tree globally for MSTP.
Disabling MSTP per port
 
Bridge2(config)#interface xe2
Enter interface mode for xe2.
Bridge2(config-if)#bridge-group 1 spanning-tree disable
Disable spanning tree per port for MSTP and put port on forwarding state. This command disables any type of STP on the port.
Validation
Bridge 1
Verify MSTP details with the show spanning-tree mst detail command.
