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.

Re: Nexus 7000 qos

This url describes how to configure Modular QoS CLI (MQC) objects that can be used for configuring QoS features using the Cisco Nexus 7000 Series NX-OS software:

Re: Nexus 7000 qos

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.

Re: Nexus 7000 qos

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,

Craig
