3. Enable byte-count or
packet-based WFQ
queuing.
qos wfq [ byte-count | weight ]
The default queuing algorithm on an
interface is WRR.
4. Assign a queue to the SP
queue scheduling group.
qos wfq queue-id group sp
By default, all the queues of a
WFQ-enabled port are in WFQ group
1.
5. Assign a queue to the WFQ
queue scheduling group,
and configure a scheduling
weight for the queue.
qos wfq queue-id group { 1 |
2 } { weight | byte-count }
schedule-value
Select weight or byte-count according to
the WFQ type (byte-count or
packet-based) you have enabled.
If you have enabled WFQ on the port,
all the queues are in WFQ group 1 by
default and the default scheduling
weight is 1 for each queue.
6. (Optional.) Configure the
minimum guaranteed
bandwidth for a queue.
qos bandwidth queue queue-id
min bandwidth-value
The default setting is 64 kbps for each
queue in a WFQ group.
Configuration example
Network requirements
• Configure SP+WFQ queuing on interface Ten-GigabitEthernet 1/0/1, and use packet-based
WFQ.
• Assign queues 0, 1, 2, and 3 to the SP group.
• Assign queues 4 and 5 to WFQ group 1, with the weights being 1 and 2, respectively, and assign
queues 6 and 7 to WFQ group 2, with the weights being 1 and 3, respectively, and configure the
minimum guaranteed bandwidth for each of the four queues as 128 Mbps.
