How to check QoS queues on an interface?

[Venison Mogambi]

Hi,

We were dropping packets across some WAN links and we found that the problem cleared up when we removed our QoS configs from the interface. So I'm thinking that some of the queues were becoming saturated with specific types of traffic. But I can't remember the commands to check individual queues. Can anyone suggest some commands to see if the different queues on our interfaces are filling up?

Thanks.

Hello Venison,

you haven't specified the platform you are interested in.

For a router with modular QoS you should be able to get  enough information from

show policy-map interface type x/y

Hope to help

I believe that's the command I was looking for. I can now see matches against different classes, drops, and so on. This is a 3825 router, by the way.

Thanks for the help!
