Example Specify the Schedule Mode as Weight Round Robin Mode: T2600G-28TS(config)# qos queue mode wrr 30.9qos queue weight Description The qos queue weight command is used to configure weight value of each queue after the Schedule Mode is specified as WRR or SP+WRR. 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, TC3, TC4, TC5,TC6 and TC7. Syntax qos queue weight { tc-id } { weight-value } Parameter tc-id -- The ID of the TC queue, ranging from 0 to 7. weight-value -- Configure the weight value of the specified TC queue. When the schedule mode is specified as WRR, the weight value ranges from 1 to 127. The 8 queues will take up the bandwidth according to their ratio. The default values of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are 1, 2, 4, 8, 16, 32, 64 and 127 respectively. When the schedule mode is specified as SP+WRR, the weight value ranges from 0 to 127. TC7 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. In this SP+WRR scheduling mode, the queues in the SP group is scheduled preferentially (TC6>TC5>TC4>TC3>TC2>TC1>TC0 in strict priority).

equ —— Equal-Mode. In this mode, all the queues occupy the bandwidth
equally. The weight value ratio of all the queues is 1:1:1:1:1:1:1:1
Command Mode
Global Configuration Mode
Privilege Requirement
Only Admin, Operator and Power User level users have access to these
commands.
Example
Specify the Schedule Mode as Weight Round Robin Mode:

qos queue weight
Description
The
qos queue weight
command is used to configure weight value of each
queue after the Schedule Mode is specified as WRR or SP+WRR. 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, TC3, TC4, TC5,TC6 and TC7.
Syntax
qos queue weight
{
tc-id
} {
weight-value
}
Parameter
tc-id
—— The ID of the TC queue, ranging from 0 to 7.
weight-value
—— Configure the weight value of the specified TC queue.
When the schedule mode is specified as WRR, the weight value ranges from 1
to 127. The 8 queues will take up the bandwidth according to their ratio. The
default values of TC0, TC1, TC2, TC3, TC4, TC5,TC6 and TC7 are 1, 2, 4, 8, 16,
32, 64 and 127 respectively.
When the schedule mode is specified as SP+WRR, the weight value ranges
from 0 to 127. TC7 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.
In this SP+WRR scheduling mode, the queues in the SP group is scheduled
preferentially (TC6>TC5>TC4>TC3>TC2>TC1>TC0 in strict priority). When
there is no packets to be sent in the SP group, the queues in the WRR group
will be scheduled according to the weight value of each queue. The default
