MSTP can be configured on a device with MRP. However, they are mutually exclusive on a specific
VLAN. Also, MSTP can be configured on a port that is part of a LAG following the same rules as used
for STP and RSTP.
Each of the commands used to configure and operate MSTP are described in the following:
• “Setting the MSTP name”
• “Setting the MSTP revision number”
• “Configuring an MSTP instance”
• “Configuring port priority and port path cost”
• “Configuring bridge priority for an MSTP instance”
• “Setting the MSTP global parameters”
• “Setting ports to be operational edge ports”
• “Setting point-to-point link”
• “Disabling MSTP on a port”
• “Forcing ports to transmit an MSTP BPDU”
• “Enabling MSTP on a device”
Setting the MSTP name
Each device that is running MSTP is configured with a name. It applies to the device which can have
many different VLANs that can belong to many different MSTP regions. By default, the name is the
MAC address of the device.
To configure an MSTP name, use a command such as the following at the Global Configuration
level.
Brocade(config)# mstp name mstp1
Syntax: [no] mstp name name
The name parameter defines an ASCII name for the MSTP configuration. The default name is the
MAC address of the device expressed as a string.
Setting the MSTP revision number
Each device that is running MSTP is configured with a revision number. It applies to the device
which can have many different VLANs that can belong to many different MSTP regions.
To configure an MSTP revision number, use a command such as the following at the Global
Configuration level.
Brocade(config)# mstp revision 4
Syntax: [no] mstp revision revision-number
The revision parameter specifies the revision level for MSTP that you are configuring on the device.
It can be a number from 0 and 65535.
