Enabling and disabling STP, RSTP, or MSTP
You enable STP to detect or avoid loops. STP is not required in a loop-free topology. You must turn
off one form of STP before turning on another form.
To enable and disable STP, RSTP, or MSTP, perform the following steps from Privileged EXEC mode:
NOTE
Using the no protocol spanning-tree command deletes the context and all the configurations defined
within the context or protocol for the interface.
Step Task Command
1. Enter global configuration mode. switch>#config t
Enter configuration commands, one
per line. End with CNTL/Z.
switch(config)#
2. Enable STP, RSTP, or MSTP. By default, STP, RSTP,
and MSTP are not enabled.
switch(config)#protocol
spanning-tree {mstp | rstp | stp}
Disable STP, RSTP, or MSTP. switch(config)#no protocol
spanning-tree
3. Display the spanning-tree configuration. switch(config)#do show spanning-tree
