Thank You for answers,

Yes, I have this command in global config.
We've added it to save DSCP transparency on the edge routers - because without it,
DSCP field is rewritten with MPLS EXP field value.
And there are a lot of client's services with policy-maps with double-set statements :
set mpls exp imposition Y
set ip dscp XX

> Try to add "mls qos rewrite ip dscp" to you global configuration.

But this will destroy DSCP transparency..
I've used this link (we have RSP720, 3CXL):
http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/rsp720.html#wp1042557

Although, I've tried to add "mls qos rewrite ip dscp", the result is the same - traffic is matched on the router, but not marked:-(


Best regards,
Olga
