Configuring PFC QoS
To allocate bandwidth between standard transmit queues, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# wrr-queue [bandwidth | shape]
percent low_priority_queue_percentage
[ intermediate_priority_queue_percentages ]
high_priority_queue_percentage
Or:
Router(config-if)# wrr-queue [bandwidth | shape]
low_priority_queue_weight
[ intermediate_priority_queue_weights ]
high_priority_queue_weight
Router(config-if)# no wrr-queue [bandwidth |
shape]
Step 3
Router(config-if)# end
Step 4
Router# show queueing interface type
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
This example shows how to allocate a 3-to-1 bandwidth ratio for Gigabit Ethernet port 1/2:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)# interface gigabitethernet 1/2
Router(config-if)# wrr-queue bandwidth 3 1
Router(config-if)# end
Router#
This example shows how to verify the configuration:
Router# show queueing interface gigabitethernet 1/2 | include bandwidth
WRR bandwidth ratios:

Chapter 41
Enter the bandwidth keyword to configure DWRR or
WRR.
Enter the shape keyword to configure SRR. Use of
SRR prevents use of the strict priority queue. To
configure SRR, any CoS or DSCP values mapped to
a strict-priority queue must be remapped to a
standard queue (see the
"Mapping QoS Labels to
Queues and Drop Thresholds" section on
page
41-99).
Percentages should add up to 100. You must enter
percentages for all the standard transmit queues on
the port. (Supported with Release 12.2(18)SXF and
later releases.)
The valid values for weight range from 1 to 255. You
must enter weights for all the standard transmit
queues on the port.
End with CNTL/Z.
