STP, RSTP, and MSTP configuration and management
NOTE
To see the minimum configuration required to enable FCoE on the Dell M8428-k switch, refer to
Chapter 3, “Initial FCoE and CEE Configuration” .
NOTE
You need to enter either the copy running-config startup-config command or the write memory
command to save your configuration changes to Flash so that they are not lost if there is a system
reload or power outage.
Enabling 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. By default, STP, RSTP, and MSTP are not
enabled.
To enable STP, RSTP, or MSTP, perform the following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the protocol command to enable STP, RSTP, or MSTP.
switch(config)#protocol spanning-tree rstp
Disabling STP, RSTP, or MSTP
NOTE
Using the no protocol spanning-tree command deletes the context and all the configurations defined
within the context or protocol for the interface.
To disable STP, RSTP, or MSTP, perform the following steps from Privileged EXEC mode. By default,
STP, RSTP, and MSTP are not enabled.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the protocol command to disable STP, RSTP, or MSTP.
switch(config)#no protocol spanning-tree
Shutting down STP, RSTP, or MSTP globally
To shut down STP, RSTP, or MSTP globally, perform the following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the shutdown command to globally shutdown STP, RSTP, or MSTP. The shutdown
command below works in all three modes.
switch(conf-mstp)#shutdown
