Christian,
I tried both in the lab. The dscp-mutation map approach worked fine just as
you wrote it, and I prefer it for its simplicity. The policy-map setting
dscp directly did not work as written. It does work with the trust statement
in a separate, class-default stanza. Traffic entering as 45 goes out as 35,
and other dscps go through unchanged.
policy-map 45to35
class 45to35
set ip dscp 35
class class-default
trust dscp
HTH,
