Hello,
I'm trying to convert our existing QoS template that we use on our 3750/3560 to work on our new Nexus 5000 switches.
The ACLs and class-maps are ok, but it seems I can't do a "set dscp xx" within the policy-map on the Nexus 5000, like I was able to using the 3750/3560.
This is what I normally configure on a 3560/3750 :
policy-map QosPolicy
class VoIP
set dscp ef
exit
class CriticalApp
set dscp af31
exit
[...]
class class-default
set dscp default
exit
exit
The "set dscp xyz" command isn't available on my Nexus 5000s. I'm running NX-OS version 4.1(3)N1(1)... I'm currently unable to download version N2 from Cisco (some cryptic error about mismatched data), so I can't verify whether "set dscp" is available there in the newer version.
Have I misunderstood something about the QoS on Nexus 5000s ?
Please advise,
Alex.

I don't know about v4.2 but as far as i know for the Nexus 5000 switches you only have the option to set CoS values. Only the L3 capable Nexus 7000 has the capability of setting DSCP values.

This is not the answer I was looking for, but the datasheet of the Nexus 5000 does indeed only mention "MQC CoS Marking" in the QoS subsection ( see http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9670/data_sheet_c78-461802.html ).
It's a shame though... 3560s with IP Base (L2) are able to do DSCP marking just fine... sigh...
Thanks Jon!
