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 reaches zero, the switch discards the
BPDU and ages out any information that it holds for the port.

bridge-priority
priority} command.
Parameters
msti instance Enter the MSTP iInstance. The range is zero (0) to 63.
vlan range Enter the keyword vlan followed by the identifier range value. The
range is 1 to 4094.
