Configuring WRR Priority

Beginning in privileged EXEC mode, follow these steps to configure the WRR priority:
Command
Step 1 configure terminal
Step 2 wrr-queue bandwidth
weight1...weight4
Step 3
end
Step 4 show wrr-queue bandwidth
To disable the WRR scheduling and enable the strict priority scheduling, use the no wrr-queue
bandwidth global configuration command.
To enable one of the queues as the expedite queue and to enable the WRR scheduling for the remaining
queues, see the

Enabling the Expedite Queue and Configuring WRR Priority

In Cisco IOS Release 12.1(12c)EA1 or later, beginning in privileged EXEC mode, follow these steps to
enable the expedite queue (queue 4) and assign WRR priority to the remaining queues:
Command
Step 1
configure terminal
Step 2 wrr-queue bandwidth weight1 weight2
weight3 0
Step 3
end
Step 4
show wrr-queue bandwidth

Purpose
Enter global configuration mode.
Assign WRR weights to the four CoS queues.
These are the ranges for the WRR values:
• For weight1, weight2, and weight3, the range is 1 to 255.
• For weight4, the range is 0 to 255. When weight4 is set to 0, queue
4 is configured as the expedite queue.
Note In software releases earlier than Cisco IOS
Release 12.1(12c)EA1, the ranges for all queues is 1 to 255.
Return to privileged EXEC mode.
Display the WRR bandwidth allocation for the CoS priority queues.
