Nexus 7k mls qos trust dscp?

Is there a way to tell a port (eth1/1) on a Nexus 7010 to trust dscp?

Normally for Unity/CallManager/IOS Voice Gateways I put a “mls qos trust dscp” on the those interface. What is Nexus equivalent?

Re: Nexus 7k mls qos trust dscp?

I'm not a Nexus 7k guy, but I did a quick search and found an engineering document that said that L3 ports on the 7k trust DSCP by default.  So as long as your DSCP->CoS and CoS->DSCP maps are set so that COS5 goes to DSCP46, you should be good to go.

If in doubt, though, grab a sniffer and verify the L3 ToS header.
