Command Reference Guide

SROS Command Line Interface Reference Guide Ethernet Interface Configuration Command Set

spanning-tree port-priority <priority level>

Use the spanning-tree port-priority command to select the priority level of this interface. To return to the

default setting, use the no version of this command.

Syntax Description

<priority level> Set to a value from 0-255.

Default Values

By default, this set to 128.

Command Modes

(config-interface)# Interface Configuration Mode

Valid interfaces include: Ethernet, virtual PPP interfaces (ppp 1), virtual Frame

Relay sub-interfaces (fr 1.20), and atm sub-interfaces (1.2).

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 spanning-tree will use. Set the

priority value lower to increase the chance the interface will be used.

Usage Examples

The following example sets the interface to a priority of 100:

(config)#interface eth 0/1

(config-eth 0/1)#spanning-tree port-priority 100
