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 switch”
Setting the MSTP name
Each switch that is running MSTP is configured with a name. It applies to the switch 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.
BigIron RX(config)# mstp name brocade
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 switch expressed as a string.
Setting the MSTP revision number
Each switch that is running MSTP is configured with a revision number. It applies to the switch
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.
BigIron RX(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 switch.
It can be a number from 0 and 65535.
Configuring an MSTP instance
An MSTP instance is configured with an MSTP ID for each region. Each region can contain one or
more VLANs. To configure an MSTP instance and assign a range of VLANs, use a command such as
the following at the Global Configuration level.
BigIron RX(config) # mstp instance 7 vlan 4 to 7
