User Guidelines By default, the mapping relation between tag and the egress queue is: (0-7)-CoS 0, (8-15)-CoS 1, (16-23)-CoS 2, (24-31)-CoS 3, (32-39)-CoS 4, (40-47)-CoS 5, (48-55)-CoS 6, (56-63)-CoS 7.

When the network is congested, the program that many packets complete for resources must be solved, usually in the way of queue scheduling.

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. The priority order: TC3>TC2>TC1>TC0. 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 and TC3 are customized in qos queue weight command and their default values are 1, 2, 4 and 8 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 based on Strict-Priority mode while the queues inside WRR group follow the WRR mode. In SP+WRR mode, TC3 and the queue with its weight value set as 0 are in the SP group; other queues, with none-zero weight value, belong to the WRR group and the weight value can be customized in qos queue weight 103

User Guidelines
By default, the mapping relation between tag and the egress queue is:
(0-7)-CoS 0, (8-15)-CoS 1, (16-23)-CoS 2, (24-31)-CoS 3, (32-39)-CoS 4,
(40-47)-CoS 5, (48-55)-CoS 6, (56-63)-CoS 7.
Example
Map DSCP values 10-12 to CoS 2:
T1600G-52TS(config)# qos queue dscp-map
10-12 2
14.5 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 and TC3.
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. The priority order:
TC3>TC2>TC1>TC0.
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 and TC3 are customized in
qos queue weight
command and
their default values are 1, 2, 4 and 8 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
based on Strict-Priority mode while the queues inside WRR group follow the
WRR mode. In SP+WRR mode, TC3 and the queue with its weight value set as
0 are in the SP group; other queues, with none-zero weight value, belong to the
WRR group and the weight value can be customized in
qos queue weight
