Chapter 2 Campus <strong>QoS</strong> <strong>Design</strong><br />
The Catalyst 6500 CatOS show qos info config 2q2t tx verification command displays the queuing and<br />
dropping parameters for 2Q2T linecards.<br />
In the example below, CoS 1 is assigned to Q1T1; CoS 0 is assigned to Q1T2; CoS values 2,3,4,6 and 7<br />
are assigned to Q2T1 and CoS 5 is assigned to Q2T2. The first thresholds are set to 40% and 80%of their<br />
respective queues, and the second thresholds set to the tail of the queue. The size ratio has been allocated<br />
30% for Q1 and 70% for Q2 and the WRR weights are set to 30:70 to service Q1 and Q2, respectively.<br />

Catalyst 6500 CatOS <strong>QoS</strong> Verification Command: show qos info runtime<br />
The Catalyst 6500 CatOS show qos info runtime verification command reports similar information as<br />
the show qos info config command, but displays the runtime information (committed to the PFC and<br />
linecard) as opposed to only the configured information.<br />
In the example below, CoS 1 is assigned to Q1T1; CoS 0 is assigned to Q1T2; CoS values 2,3,4,6 and 7<br />
are assigned to Q2T1 and CoS 5 is assigned to Q2T2. The first thresholds are set to 40% and 80% of<br />
their respective queues, and the second thresholds set to the tail of the queue. The size ratio has been<br />
allocated 30% for Q1 and 70% for Q2 and the WRR weights are set to 30:70 to service Q1 and Q2,<br />
respectively.<br />
