I used extended ping with ToS of 0xb8 to generated EF traffic. I see the EF packets matching the VoIP Media class map but not to the priority queue (as seen in the output from "show policy-map int s2/0" command):
You might misunderstand the stats. If your concern is the zero matches for the PQ, that can indicate there wasn't enough congestion for that class's matched packets to be queued. It's common to see this stat, on any class that shows it, less than the class match stats. This might be confirmed by the fact your parent shaper shows zero delayed packets. (Only when the shaper delays packet should packets be queued into the child policy's queues.)
BTW, what kind of serial link is it that you needed to shape it to 1.5 Mbps?
Thanks much Joseph. I suspected that this is what the case is. The original policy is for a DS3 link on a customer's 7206VXR but I am simulating this for a serial interface in the lab environment. Personally, I think we don't need to shape a DS3 link unless we want it to be under utilized. What do you think?
Perhaps I should generated large datagrams on this 1.5Mbps link to saturate it and lower down the traffic shaping limit to see the packets in the strict priority queue. I will keep you posted if I get that working.
Marwan - Thanks for pointing out the match-any thing to. It would be a good idea for that class-map. However, the problem I suspected I was seeing was with the VoIP_Media class with already has match-any statement.
As to seeing LLQ activate in a test situtation, I've found an easy method to do so is to use some kind of traffic generator to fill bandwidth with "background" traffic. I've also used your idea of setting a shaper slower to see the effect too.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
