Privilege Requirement Only Admin, Operator and Power User level users have access to these commands. User Guidelines By default, the mapping relation between DSCP value and the egress queue is: (0-7)-TC 0, (8-15)-TC 1, (16-23)-TC 2, (24-31)-TC 3, (32-39)-TC 4, (40-47)-TC 5, (48-55)-TC 6, (56-63)-TC 7. Example Map DSCP values 10-12 to TC 2: T2500G-10MPS(config)# qos queue dscp-map 10-12 2 24.6 qos queue mode Description The qos queue mode command is used to configure the Schedule Mode. To return to the default Equal-Mode, please use no qos queue mode 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,TC2 ... TC7. Syntax qos queue mode { sp | wrr | spwrr | equ } no qos queue mode 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. wrr -- Weight Round Robin Mode. In this mode, packets in all the queues are sent in order based on the weight value for each queue. The weight values of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are customized in qos queue weight command and their default values are 1, 2, 4, 8, 16, 32, 64 and 127 respectively. spwrr -- Strict-Priority + Weight Round Robin Mode. In this mode, the switch provides two scheduling groups, SP group and WRR group. SP group is processed prior to WRR group. Queues in SP group are scheduled strictly 211
