[kanwar]

Hi,

Have a qucik question about how Nexus treats the DSCP markings, if  a paket comes in with alreay marked EF, does it get overwritten by the Nexus policy ??

Thanks

Hi,

The default behavior for nexus 7000 is trust DSCP.

"The default behavior of the device is to preserve the DSCP value, or to trust DSCP"
