Cat6500 QoS - priority-queue queue-limit

Hi,

CCO documentation states that

"priority-queue queue-limit" command is supported in 12.2.18SXF2 and above for Cat 6500, Sup720-3b.

For IOS below 12.2.18SXF2, what is the buffer that is allocated for priority queue?

Using 1P3Q8T as an example, if i have the command

wrr-queue queue-limit 0 50 20

Using 12.2.18SXF2 and above, i am able to use "priority-queue queue-limit" command to set the buffer allocated for priority queue. "show queueing interface x/y" is also able to show that x amount of buffer is allocated for priority queue.

However, using 12.2.18SXF2 and below,

Does that mean that remaining 30% (100-50-20) of the buffer will be allocated for priority queue since i cannot use "priority-queue queue-limit" command to set it. Using "show queueing interface x/y" does not show how much buffer is allocated to priority queue.

Is there a way i can see the buffer allocated for priority queue in 12.2.18SXF2 and below?

Thanks

Eng Wee

Re: Cat6500 QoS - priority-queue queue-limit

attached is the "show queueing interface" output using IOS with 12.2.18SXF2 and below. It does not indicate the buffer allocated for priority queue (Q8).

Also attached the same show output using IOS 12.2.18SXF11 which does indicate the buffer allocation for priority queue.
