stp port priority

Syntax
stp [ instance instance-id ] port priority priority
undo stp [ instance instance-id ] port priority
View
Ethernet port view
Parameters
instance-id: MSTI ID ranging from 0 to 16. The value of 0 refers to the CIST.
port priority priority: Sets the port priority. The priority argument ranges from 0 to 240 and must be a
multiple of 16 (such as 0, 16, and 32).
Description
Use the stp port priority command to set the port priority of the current port in the specified MSTI.
Use the undo stp port priority command to restore the default port priority of the current port in the
specified MSTI.
The default port priority of a port in any MSTI is 128.
If you specify the instance-id argument to 0 or do not specify the argument, the two commands apply to
the port priorities of ports on the CIST. The role a port plays in a MSTI is determined by the port priority
in the instance. A port on a MSTP-enabled switch can have different port priorities and play different
roles in different MSTIs. This enables packets of different VLANs to be forwarded along different
physical links, so as to implement VLAN-based load balancing. Changing port priorities result in port
role recalculation and state transition.
