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.

no spanning-tree max-hops
number Maximum hops for which the BPDU will be valid. The range is 1 to 40.

Usage

network. When a bridge receives an MST BPDU that has exceeded the allowed maximum hops, it
discards the BPDU.
