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.
msti
Configure multiple spanning tree instance, bridge priority, and one or multiple VLANs mapped to the MST instance.
