priority
Required.
The default port priority is
128.
Changing port priority of a port may change the role of the port and put the port into
state transition.
A smaller port priority value indicates a higher possibility for the port to become the root
port. If all the ports of a switch have the same port priority value, the port priorities are
determined by the port indexes. Changing the priority of a port will cause spanning tree
recalculation.
You can configure port priorities according to actual networking requirements.
III. Configuration example
# Configure the port priority of Ethernet1/0/1 in spanning tree instance 1 to be 16.
1) Perform this configuration in system view
<Sysname> system-view
[Sysname] stp interface Ethernet1/0/1 instance 1 port priority 16
2) Perform this configuration in Ethernet port view
<Sysname> system-view
[Sysname] interface Ethernet1/0/1
[Sysname-Ethernet1/0/1] stp instance 1 port priority 16
