Usage
Information
The max-hops command is a configuration command that applies to both the IST
and all MST instances in the MSTP region. The BPDUs sent out by the root switch
set the remaining-hops parameter to the configured value of max-hops. When a
switch receives the BPDU, it decrements the received value of the remaining hops
and uses the resulting value as remaining-hops in the BPDUs. If the remaining-
hops reach zero, the switch discards the BPDU and ages out any information that it
holds for the port.
