HP 7000 dl Router manual Spanning-tree port-priority value

SROS Command Line Interface Reference Guide ATM Sub-Interface Config Command Set

spanning-tree port-priority <value>

Use the spanning-treeport-prioritycommand 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>	Priority value for the bridge group; the lower the value, the higher the priority (valid
	range: 0 to 255)

Default Values

<value> 128

Command Modes

(config-interface)#	Interface Configuration Mode
	Valid interfaces include: ATM sub-interface, Ethernet, virtual PPP interfaces, and
	virtual Frame Relay sub-interfaces.

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
