Optional
128 for all Ethernet ports by
default.
z
When the priority of a port is changed, MSTP will re-calculate the role of the port and initiate a state
transition.
z
Generally, a lower configured value indicates a higher priority. If you configure the same priority
value for all the ports on a device, the specific priority of a port depends on the index number of the
port. Changing the priority of a port triggers a new spanning tree calculation process.
Configuration example
# Set the priority of port GigabitEthernet 1/0/1 to 16 in MSTI 1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
