This example shows how to verify the configuration:

Router# show queueing interface gigabitethernet 1/1 | begin Transmit queues 

  Transmit queues [type = 1p2q2t]:

Router# 

On 1q4t/2q2t ports, the receive- and transmit-queue drop thresholds have this relationship:

Receive queue 1 (standard) threshold 1 = transmit queue 1 (standard low priority) threshold 1

Receive queue 1 (standard) threshold 2 = transmit queue 1 (standard low priority) threshold 2

Receive queue 1 (standard) threshold 3 = transmit queue 2 (standard high priority) threshold 1

Receive queue 1 (standard) threshold 4 = transmit queue 2 (standard high priority) threshold 2

To configure tail-drop threshold percentages for the standard receive and transmit queues on 1q4t/2q2t 
LAN ports, perform this task: 

When configuring the receive- and transmit-queue tail-drop thresholds, note the following:

You must use the transmit queue and threshold numbers.

The queue_id is 1 for the standard low-priority queue and 2 for the standard high-priority queue.

The percentages range from 1 to 100. A value of 10 indicates a threshold when the buffer is 
10-percent full.

Always set threshold 2 to 100 percent.

Ethernet and Fast Ethernet 1q4t ports do not support receive-queue tail-drop thresholds.

Router(config)# interface {ethernet | 

 | gigabitethernet} slot/port 

Selects the interface to configure.

Router(config-if)# wrr-queue threshold queue_id 

thr1% thr2% 

Configures the receive- and transmit-queue tail-drop 
thresholds. 

Router(config-if)# no wrr-queue threshold 

[queue_id]

Reverts to the default receive- and transmit-queue 
tail-drop thresholds. 

Router(config-if)# end 

Exits configuration mode.

Router# show queueing interface {ethernet | 

 | gigabitethernet} slot/port 

Verifies the configuration.
