Advanced Configuration and Management Guide

USING THE WEB MANAGEMENT INTERFACE

1.Log on to the device using a valid user name and password for read-write access. The System configuration dialog is displayed.

2.Click on the Port link to display the Port table.

3.Scroll down to the port for which you want to change the QoS level, then click on the Modify button to the right of the port information to display the Port configuration panel, as shown in the following example.

4.Select a QoS level from 0 – 7 from the QoS field’s pulldown menu.

5.Click the Apply button to save the change to the device’s running-config file.

6.Select the Save link at the bottom of the dialog, then select Yes when prompted to save the configuration change to the startup-config file on the device’s flash memory.

Changing a Layer 2 Port-Based VLAN’s Priority

By default, VLANs have priority 0 (the best effort queue, qosp0). To change a port-based VLAN’s QoS priority, use one of the following methods. The priority applies to outbound traffic on ports in the VLAN.

NOTE: Tagged packets also contain a priority value in the 802.1q tag. If you use the default priority for a VLAN, a tagged packet that exits on that VLAN can be placed into a higher priority queue based on the port priority, the priority in the 802.1q tag, and so on. If you do not want the device to make priority decisions based on 802.1q tags, you can change the priority for 802.1q tags on a VLAN basis. See “Reassigning 802.1p Priorities to Different Queues” on page 2-14”.

USING THE CLI

To change the QoS priority of port-based VLAN 20 to the premium queue (qosp3), enter the following commands:

HP9300(config)# vlan 20

HP9300(config-vlan-20)# priority 7

HP9300(config-vlan-20)# write memory

Syntax: [no] priority <num>

The <num> parameter can be from 0 – 7 and specifies the IEEE 802.1 equivalent to one of the four QoS queues.
