Note Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic 3. If you want 802.1p priority settings to be included in outbound packets, ensure that tagged VLANs are configured on the appropriate downstream links. 4. Determine the actual QoS configuration changes you will need to make on each QoS-capable device in your network in order to implement the desired policy. Also, if you want downstream devices to read and use DSCPs in IP packets from the switch, configure them to do so by enabling ToS Differentiated Service mode and making sure the same DSCP policies are configured. Using QoS Classifiers To Configure Quality of Service for Outbound Traffic QoS Feature Default UDP/TCP Priority Disabled IP-Device Priority Disabled IP Type-of-Service Priority Disabled Protocol Priority Disabled VLAN-ID Priority Disabled Source-Port Priority Disabled Menu - - - - - - CLI Web page 5-15 Refer to Online Help. page 5-22 " page 5-26 " page 5-38 " page 5-41 " page 5-46 " In addition to the information in this section on the various QoS classifiers, refer to "QoS Operating Notes and Restrictions" on page 5-72. Viewing the QoS Configuration All of these commands are available on the switches covered in this guide. Examples of the show qos output are included with the example for each priority type. Syntax: show qos < priority-classifier > tcp-udp-port-priority Displays the current TCP/UDP port priority configuration. Refer to figure 5-6 on page 5-22. 5-13
