Shutting down STP

Follow these steps to o shut down STP either globally, on a specific interface, or a specific VLAN.

1. Enter global configuration mode.
   

   device# configure terminal
   

2. Shut down STP.

   • Shut down STP globally and return to privileged EXEC mode.

     

     device(config)# protocol spanning-tree stp
     device(config-stp)# shutdown
     device(config-stp)# end
     

   • Shut down STP on a specific interface and return to privileged EXEC mode.

     

     device(config)# interface ethernet 0/2
     device(conf-if-eth-0/2)# spanning-tree shutdown
     device(conf-if-eth-0/2)# end
     

   • Shut down STP on a specific VLAN and return to privileged EXEC mode.

     

     device(config)# vlan 10
     device(config-vlan-10)# spanning-tree shutdown
     device(config-vlan-10)# end
     

3. Verify the configuration.
   

   device# show spanning-tree 
   device# 
   

4. Save the running configuration to the startup configuration.
   

   device# copy running-config startup-config
   

Shut down STP configuration example

device# configure terminal
device(config)# vlan 10
device(config-vlan-10)# spanning-tree shutdown
device(config-stp)# end
device# show spanning-tree 
device# copy running-config startup-config

Note

Shutting down STP on a VLAN is used in this example.
