DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide Parameter Description packets transmitted from the queue cannot exceed the maximum bandwidth even if the bandwidth is available. When configuring the minimal bandwidth, the aggregate of the configured minimum bandwidth must be less than 75 percent of the interface bandwidth to make sure the configured minimal bandwidth can be guaranteed. It is not necessary to set the minimum guaranteed bandwidth for the highest strict priority queue. This is because the traffic in this queue will be serviced first if the minimal bandwidth of all queues is satisfied. The configuration of this command can only be attached to a physical port but not a port-channel. That is the minimum guaranteed bandwidth of one CoS cannot be used across physical ports. • When the Min Percent option is selected, enter the minimum bandwidth percentage value in the space provided. This value must be between 1 and 100 percent (%). Also enter the maximum percentage value (Max Percent) in the space provided. This value must be between 1 and 100 percent (%). Click the Apply button to accept the changes made. Advanced Settings DSCP Mutation Map This window is used to display and configure the Differentiated Services Code Point (DSCP) mutation map settings. When a packet is received by an interface, based on a DSCP mutation map, the incoming DSCP can be mutated to another DSCP immediately before any QoS operations. The DSCP mutation is helpful to integrate domains with different DSCP assignments.The DSCP-CoS map and DSCP-color map will still be based on the packet's original DSCP. All the subsequent operations will base on the mutated DSCP. To view the following window, click QoS> Advanced Settings > DSCP Mutation Map, as shown below: Figure 7-7DSCP Mutation Map Window The fields that can be configured are described below: Parameter Mutation Name Input DSCP List Description Enter the DSCP mutation map name here.
