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 access global configuration mode.

2.Enter the protocol command to enable MSTP.

switch(config)#protocol spanning-tree mstp

3.Enter the max-hopscommand to configure the maximum number of hops for a BPDU in an MSTP region.

switch(conf-mstp)#max-hops hop_count

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.

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(conf-mstp)#region sydney

Specifying a revision number for an 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.

To specify a revision number for an MSTP configuration, 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 MSTP.

switch(config)#protocol spanning-tree mstp

3. Enter the revision command to specify a revision number for an MSTP configuration.

switch(conf-mstp)#revision 17
