Protocol Spanning Tree MSTP mode
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. Use the no max-hops command to return to the
default value.
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.
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
