6.2.5 Configure QoS Quality of Service (QoS) configuration is a 3-step process: 1. Create class maps to classify traffic. 2. Create QoS and policy maps for the classified traffic. 3. Apply the QoS and policy maps. FCoE traffic is assigned dot1p priority value 3 by default. In the following tables, dot1p priority value 3 is mapped to QoS group 3. The remaining dot1p priority values, 0-2 and 4-7, are mapped to QoS group 0. QoS group 3 is mapped to queue 3, and QoS group 0 is mapped to queue 0. In this example, bandwidth is allocated 50% to queue 3 for FCoE traffic and 50% to queue 0 for all other traffic using the bandwidth percent command. (Bandwidth allocations should total 100% and may be adjusted accordingly to optimize traffic). Finally, exit configuration mode and save the configuration with the end and write memory commands.
