Follow the steps below to change the spanning tree port priority.
Step
Command
Description
Step 1
configure terminal
Enters the configuration mode
Step 2
interface <interface-type><interface-id>
or
interface range <interface-type><interface-id> ….
Enters the port interface mode.
interface-type – may be any of the
following:
fx-ethernet – fx
cx-ethernet – cx
port-channel – po
interface-id is in slot/port format for all
physical interfaces. It may be the port
channel identifier for port channel
interfaces.
To configure multiple interfaces, use
the “interface range …” command. To
provide a range use a hypen (-)
between the start and end interface
numbers.
E.g.: int range fx 0/1-10
To provide multiple interfaces or
ranges, use separate with a comma (,).
E.g.: int range fx 0/1-10, fx 0/20
Step 3
To configure the port priority in RST mode:
spanning-tree port-priority <priority-value>
To configure the port priority for the default MST
instance 0:
spanning-tree port-priority <priority-value>
To configure the port priority for particular MST
instance:
spanning-tree mst <instance-id>port-priority
<priority-value>
Configures the port spanning tree
priority.
priority-value – Spanning tree port
priority value may be from 0 to 240.
Priority value must be multiple of 16.
The default priority value is 128.
instance-id – The MST instance
identifier may be from 1 to 16.
Step 4
end
Exits the configuration mode.
Step 5
show spanning-tree interface <interface-
type><interface-id>
Displays the spanning tree port
parameters including the port priority
values.
Step 6
write startup-config
Optional step – saves this spanning tree
configuration to be part of startup
configuration.
