Guys,
I have 48 CEF720 48 port 10/100/1000mb Ethernet WS-X6748-GE-TX card, and I thought it using 1p3q8t techniques, but for some reason when i try to add this configuration to any interface on the card
wrr-queue bandwidth 5 25 70
wrr-queue queue-limit 5 25 40
wrr-queue cos-map 1 1 1
wrr-queue cos-map 2 1 0
wrr-queue cos-map 3 1 4
wrr-queue cos-map 3 2 2
wrr-queue cos-map 3 3 3
wrr-queue cos-map 3 4 6
wrr-queue cos-map 3 5 7
priority-queue cos-map 1 5
mls qos trust dscp
it does not accept some commands, shuch as wrr-queue cos-map 3 x x
And wrr-queue bandwidth 5 25 70
Does this card really supports 1p3q8t?
Thanks in advance..

What do you see when you do a
"show queueing interface Gix/x" for any interface you have on that card?
I would also like to know what version of IOS you are using?

The IOS version is fine 12.2.18SXD..
Some commands work fine, such as
wrr-queue cos-map 2 2 3
But when the command wrr-queue cos-map starts with 3 it does not work, so it looks like it's only 2q not 3q, however accoring to Cisco it should be 1p3q8t..

I recently installed some 6509-E's with Sup720's and some WS-X6748-GE-TX modules and I didn't have a problem configuring this:
interface GigabitEthernet3/1
switchport
switchport access vlan 6
no ip address
wrr-queue bandwidth 5 25 70
wrr-queue queue-limit 5 25 40
wrr-queue random-detect min-threshold 3 50 60 70 80 90 100 100 100
wrr-queue random-detect max-threshold 1 100 100 100 100 100 100 100 100
wrr-queue random-detect max-threshold 2 100 100 100 100 100 100 100 100
wrr-queue random-detect max-threshold 3 60 70 80 90 100 100 100 100
wrr-queue cos-map 1 1 1
wrr-queue cos-map 2 1 0
wrr-queue cos-map 3 1 4
wrr-queue cos-map 3 2 2
wrr-queue cos-map 3 3 3
wrr-queue cos-map 3 4 6
wrr-queue cos-map 3 5 7
mls qos trust dscp

I was however running 12.2(18)SXF3. The documentation states the WS-X6748-GE-TX has the transmit queue structure 1P3Q8T so it should work. Are you sure it is a 6748 and not a 6548? If you do a 'show interface capabilities' it will show you what the tx queue structure is.

Thanks Andrew..
So now, is the queue structure is software dependent or hardware? I mean if I upgraded the IOS will that change the queue structure for the card?

It should be hardware dependant, although I wouldn't rule out an IOS issue. I have briefly looked through the release notes and can't see anything that looks like your problem.
I assume the output from 'show interface capabilities' show the TX queue structure as 1P3Q8T? If so either open a TAC case or just put a later IOS on. 12.2(18)SXD has been deferred anyway so it is advisable to move to 12.2(18)SXD7 (all earlier 12.2(18)SXx releases have software advisories against them).

Whoops, I meant to say:
all earlier 12.2(18)SXDx releases have software advisories against them....
