region.

Description Use this command to configure the maximum number of hops for a BPDU in an MSTP region.
This parameter is used by all the instances of the MSTP.
Usage Guidelines 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.
This command functions only in standalone mode.
Enter no max-hops to return to the default value.
Examples To set the number of maximum hops to 25 for all MSTPs:
switch(config)# protocol spanning-tree mstp
switch(conf-mstp)# max-hops 25
