Convert QoS Config From IOS to NX-OS

Hi ,

I'm trying to convert QoS configuration from 6500 to N7K , the configuration I have is as follows :

mls qos

mls qos map dscp-cos 32 to 5

interface GigabitEthernet1/1/2

description Telepresence Switch

switchport

switchport trunk encapsulation dot1q

switchport mode trunk

mls qos trust dscp

interface GigabitEthernet1/1/6

no switchport

ip address 192.168.1.1 255.255.255.0

mls qos trust dscp

According to this article : https://supportforums.cisco.com/docs/DOC-20595

mls qos This is not needed , QoS is always enabled on Nexus 7000.

interface range gig3/1-48

mls qos trust dscp

Also not needed, DSCP is trusted by default. For L2 bridged IP traffic, DSCP is never modified by default; for L3 routed IP traffic, DSCP is used to rewrite outbound COS.

My issue is the command “ mls qos map dscp-cos 32 to 5” we are mapping dscp : 32 to CoS 5 , and this is not the default mapping in Nexus, I think DSCP 40 is mapped to CoS 5 in N7K .

How can I do the same mapping I have “mls qos map dscp-cos 32 to 5” in N7K?

Thanks

Ali
