7.7 spanning-tree max-hops
Use this command to specify the maximum allowed hops for a BPDU in an MST region. This
parameter is used by all the instances of the MST. To restore the default value, use the no parameter
with this command.
Command Syntax
spanning-tree max-hops number
no spanning-tree max-hops
number Maximum hops for which the BPDU will be valid. The range is 1 to 40.
Command Mode

Default
The default maximum hops in an MST region are 20.
Usage
Specifying the maximum hops for a BPDU prevents the messages from looping indefinitely in the
network. When a bridge receives an MST BPDU that has exceeded the allowed maximum hops, it
discards the BPDU.
Examples
Switch# configure terminal
Switch(config)# spanning-tree max-hops 25
