Use either command.
Configurations made in Ethernet
interface view will take effect on the
current port only; configurations made
in port group view will take effect on
all ports in the port group.
Configure the port priority
stp [ instance instance-id ]
port priority priority
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 priority indicates a higher priority of the port. If you configure
the same priority value for all the Ethernet ports on a device, the specific priority of a port depends
on the index number of that port. Changing the priority of an Ethernet port triggers a new spanning
tree calculation process.
Configuration example
# Set the priority of port GigabitEthernet 0/0/1 to 16 in MST instance 1.
<Sysname> system-view
[Sysname] interface GigabitEthernet 0/0/1
[Sysname-GigabitEthernet0/0/1] stp instance 1 port priority 16
