This requires the use of 802.1q-based VLANS on thenetwork, as it is based on 802.1p Class of Service (CoS) marking. The QoS classification function supportsboth external and internal modes. In External mode, when the NSE received packets with 802.1p priority bitsalready set, it will pass the priority values through unaltered. In Internal mode, classification and resultant bitmarking is performed via QoS policies that are defined within the NSE. The two modes can also be used incombination.NSE provides support for DSCP (Differentiated Services Code Point) marking. You can use the two QoSmechanisms individually or concurrently.DSCP and 802.1p can be enabled individually, or simultaneously, in the global QoS configuration. You candefine the rules and parameters for each within individual QoS policies. Both use the existing TrafficDescriptor definitions. The NSE does not do any traffic shaping; traffic is marked based on defined policies,or existing marking is passed through.1. From the Web Management Interface, click on Configuration, then QoS. The QoS Settings screenappears:2. Enable 802.1P Marking and select a classification mode to mark packets using 802.1p Class of Servicevalues.3. Enable DSCP Marking and select a classification mode to mark packets using DSCP values. Note thatthe External classifier only mode is not available for DSCP; this is the default mode if DSCP is disabled.The following chart outlines the DSCP processing flow.
