Configuring Quality of Service Configuring QoS - General 20 To map DSCP to queues: STEP 1 Click Quality of Service > General > DSCP to Queue. The DSCP to Queue page is displayed. The DSCP to Queue page contains Ingress DSCP. It displays the DSCP value in the incoming packet and its associated class. STEP 2 Select the Output Queue (traffic forwarding queue) to which the DSCP value is mapped. STEP 3 Click Apply. The Running Configuration file is updated. Configuring Bandwidth The Bandwidth page enables users to define two values, Ingress Rate Limit and Egress Shaping Rate, which determine how much traffic the system can receive and send. The ingress rate limit is the number of bits per second that can be received from the ingress interface. Excess bandwidth above this limit is discarded. The following values are entered for egress shaping: • Committed Information Rate (CIR) sets the average maximum amount of data allowed to be sent on the egress interface, measured in bits per second • Committed Burst Size (CBS) is the burst of data that is allowed to be sent, even though it is above the CIR. This is defined in number of bytes of data. To enter bandwidth limitation: STEP 1 Click Quality of Service > General > Bandwidth. The Bandwidth page is displayed. The Bandwidth page displays bandwidth information for each interface. The % column is the ingress rate limit for the port divided by the total port bandwidth. STEP 2 Select an interface, and click Edit. The Edit Bandwidth page is displayed. STEP 3 Select the Port or LAG interface. Cisco Small Business 200 Series Smart Switch Administration Guide 279
