Nexus 7000 qos

I'm a little confused with the qos configuration on the Nexus 7k. Basically, we are prioritizing at edge Voice bearer traffic to DSCP 46/COS 5, signaling to DSCP 26/COS 3, Video conf to DSCP 34/Cos 4 and Streaming video to COS 4/dscp 32. That is all working on the downstream switches, we just want to match that traffic and have it enter the proper queues. I understand now the default VDC is where the queueing must be config'ed, but its only allowing me to match COS values? Need a bit of help here.

I've already looked at the configuration guides and they have not proved useful enough. I've found out that finding a command as simple as in IOS 'show policy map interface' to find out if packets are matching doesn't exist in NxOS, and was told to do a packet trace. I'm hoping the coming versions of software address issues like this.

Good info about the nexus, that seems like something that should have been included for verification.

Not trying to add insult to injury, but the documentation I found does show a "show policy-map interface" as a means of testing QoS.

You mentioned you already went through the documents, so I'm merely linking as a courtesy, unfortunately i have no Nexus to play with or I would be writing class maps right now :)

Wish I could help with the real issue, good luck with the Nexus.

Best Regards,
