History
Usage The max-hops command is a configuration command that applies to both the IST
Information
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.
Syntax
msti instance {vlan range | bridge-priority priority}
To disable mapping or bridge priority, use the no msti instance {vlan range
| bridge-priority priority} command.
Parameters
msti instance
vlan range
bridge-priority
priority
902
