Parameter dscp-list -- List of DSCP value. One or several DSCP values can be typed using comma to separate. Use a hyphen to designate a range of values, for instance, 1, 4-7, 11 indicates choosing 1, 4, 5, 6, 7 and 11. The DSCP value ranges from 0 to 63. tc-id -- The priority level the packets with tag are mapped to. It ranges from 0 to 3, which represent TC0, TC1, TC2, TC3 respectively. Command Mode Global Configuration Mode User Guidelines 1. By default, DSCP values 0-15 are mapped to TC0, DSCP values 16-31 are mapped to TC1, DSCP values 32-47 are mapped to TC2, and DSCP values 48-63 are mapped to TC3. 2. Among the priority levels TC0-TC3, the bigger value, the higher p r i o r i t y. Example Map DSCP values 10,11,15 to TC0: TP-LINK(config)# qos dscp config 10,11,15 0 qos scheduler Description The qos scheduler command is used to configure the Schedule Mode. To return to the default configuration, please use no qos scheduler command. When the network is congested, the program that many packets complete for resources must be solved, usually in the way of queue scheduling. The switch will control the forwarding sequence of the packets according to the priority queues and scheduling algorithms you set. On this switch, the priority levels are labeled as TC0, TC1... TC3. Syntax qos scheduler {sp | wrr | sp+wrr | equ} no qos scheduler Parameter sp -- Strict-Priority Mode. In this mode, the queue with higher priority will occupy the whole bandwidth. Packets in the queue with lower priority are sent only when the queue with higher priority is empty. 127
