QOS by VLAN on Nexus 5k?

Hi there,

I have a couple of Nexus 5ks that I want to put QOS on for the servers running behind it but also have voice running across it.  Voice doesn't play well with jumbo frames so I'd like to put QOS only on the voice vlan.  Is that possible?  I haven't had any luck with the Cisco config docs such as:

http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration/guide/cli/QoS.html

Thanks.

It really depend on how you want to implement the QoS policy.

You can match voice packets and mark/queue them and assign a normal ethernet size of 1500 bytes while other to jumbo frame.
