Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers to Configure Quality of Service for Outbound Traffic QoS Source-Port Priority QoS Classifier Precedence: 2 The QoS source-port option enables you to use a packet's source-port on the switch as a QoS classifier. Where a particular source-port classifier has the highest precedence in the switch for traffic entering through that port, then traffic received from the port is marked with the source-port classifier's configured priority level. Different source-port classifiers can have different priority levels. Options for Assigning Priority on the Switch. Priority control options for packets from a specified source-port include: ■ 802.1p priority ■ DSCP policy (Assigning a new DSCP and an associated 802.1p priority; inbound packets must be IPv4.) (For operation when other QoS classifiers apply to the same traffic, refer to "Classifiers for Prioritizing Outbound Packets" on page 5-10.) Options for Assigning Priority From a RADIUS Server. You can use a RADIUS server to impose a QoS source-port priority during an 802.1X portaccess authentication session. Refer to the RADIUS chapter in the Access Security Guide for your switch. Assigning a Priority Based on Source-Port This option assigns a priority to all outbound packets having the specified source-port. You can configure this option by either specifying the source-port ahead of the qos command or moving to the port context for the port you want to configure for priority. (If you are configuring multiple source-ports with the same priority, you may find it easier to use the interface < port-list > command to go to the port context instead of individually configuring the priority for each port.) Syntax: interface < port-list > qos priority < 0 - 7 > Configures an 802.1p priority for packets entering the switch through the specified (source) ports. This priority determines the packet queue in the outbound port(s) to which traffic is sent. If a packet leaves the switch on a tagged port, it carries the 802.1p priority with it to the next downstream device. You can configure one QoS classifier for each sourceport or group of source-ports. (Default: No-override) 5-27
