Configuring QoS
DiffServ Configuration
Queue Weight
Configure the weight value of the each TC queue.
In WRR mode, 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.
In SP+WRR mode, 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 (TC7>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 weight
values of TC0, TC1, TC2, TC3, TC4, TC5 and TC6 are 1, 2, 4, 8, 16, 32 and 64
respectively, while the value of TC7 is 0 and non-configurable.
3) Click

.
Note:
With ACL Redirect feature, the switch maps all the packets that meet the configured ACL rules to
the new TC queue, regardless of the mapping relations configured in this section.
2.2 Using CLI
2.2.1 Configuring Priority Mode
The instructions of the three priority modes are described respectively in this section.
Configuring 802.1 Priority
Step 1
configure
Enter global configuration mode
Step 2
qos cos
Enable the 802.1P priority.
Step 3
qos queue cos-map {
tag-id
/
cos-id
} {
tc-id
}
Configure the Tag-id-TC queues mapping relations or the CoS-id-TC mapping relations.
tag-id:
Specify the Tag-ID. The valid values are from 0 to 7.
cos-id
: Specify the CoS-ID. The valid values are from 0 to 7.
tc-id
: Specify the TC-ID. The valid values are from 0 to 7.
Step 4
show qos status
Verify that 802.1P priority is enabled.
show qos cos-map
Verify the mapping relations between the Tag-id / CoS-id and TC queues.
