spanning-tree port-priority <value>
Use the spanning-tree port-priority command to select the priority level of a port associated with a
bridge. To return to the default bridge-group priority value, use the no version of this command.
Syntax Description
<value> Assigns a priority value for the bridge group; the lower the value, the higher the
priority (valid range: 0 to 255).
Default Values
By default, the bridge-group priority value is set to 128.
Applicable Platforms
This command applies to the NetVanta 300, 1000R, 3000, and 4000 Series units.
Command History
Release 1.1 Command was introduced.
Release 8.1 ATM sub-interface was added.
Functional Notes
The only time that this priority level is used is when two interfaces with a path to the root have equal cost.
At that point, the level set in this command will determine which port the bridge will use. Set the priority
value lower to increase the chance the interface will be used.
Usage Examples
The following example sets the maximum priority on the ATM sub-interface labeled 1.1 in bridge
group 17:
(config)#interface atm 1.1
(config-atm 1.1)#spanning-tree priority 0
