Usage:
Use this command to specify the maximum allowed hops for BPDU in an MST region. This
parameter is used by all the instances of the MST. Specifying the max hops for a BPDU
prevents the messages from looping indefinitely in the network. When a bridge receives a
MST BPDU that has exceeded the allowed max-hops, it discards the BPDU.

no bridge GROUP max-hops
GROUP <1-1> Specify the bridge-group ID.
HOP_COUNT Maximum hops the BPDU will be valid for.
