Usage Information The max-hops command is a conguration 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
congured 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.
msti
