To map a VLAN to an MSTP instance, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable MSTP.
switch(config)# protocol spanning-tree mstp
3. Map a VLAN to an MSTP instance.
switch(config-mstp)# instance 5 vlan 300
4. Return to privileged EXEC mode.
switch(config-mstp)# end
5. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Specifying the maximum number of hops for a BPDU (MSTP)
In MSTP mode, use this command to configure the maximum number of hops for a BPDU in an MSTP
region. Specifying the maximum hops for a BPDU prevents the messages from looping indefinitely on
the interface. When you change the number of hops, it affects all spanning tree instances. The range
is 1 through 40. The default is 20 hops.
To configure the maximum number of hops for a BPDU in an MSTP region, perform the following
steps from privileged EXEC mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable MSTP.
switch(config)# protocol spanning-tree mstp
3. Enter the max-hops command to configure the maximum number of hops for a BPDU in an MSTP
region.
switch(config-mstp)# max-hops hop_count
4. Return to privileged EXEC mode.
switch(config-mstp)# end
5. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Specifying a name for an MSTP region
In MSTP mode, use this command to assign a name to an MSTP region. The region name has a
maximum length of 32 characters and is case-sensitive.
To assign a name to an MSTP region, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable MSTP.
switch(config)# protocol spanning-tree mstp
3. Enter the region command to assign a name to an MSTP region.
switch(config-mstp)# region sydney
4. Return to privileged EXEC mode.
switch(config-mstp)# end
5. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Specifying a revision number for MSTP configuration
In MSTP mode, use this command to specify a revision number for an MSTP configuration. The range
is 0 through 255. The default is 0.
