STP, RSTP, and MSTP configuration and management

DRAFT: BROCADE CONFIDENTIAL

STP, RSTP, and MSTP configuration and management

NOTE

To see the minimum configuration required to enable FCoE on the Brocade 8000 switch, refer to

“Minimum CEE configuration to allow FCoE traffic flow” on page 29.

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.

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.

Example

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
