Hi,
I think the difference reside onthe fact that 12.2T implement qos for ipv6 protocol.
the command set dscp instruct the router to set dscp for both ipv4 and ipv6 packet.
in the doc "implementing IPv6 for cisco ios software - implementing ipv6":
Create classes based on the criteria you establish for your network. In particular, if the same network
is also carrying IPv4 traffic along with IPv6, decide if you want to treat both of them the same way
or treat them separately and specify match criteria accordingly. If you want to treat them the same,
use match statements such as match precedence, match dscp, set precedence, and set dscp. If you
want to treat them separately, add match criteria such as match protocol ip and match protocol
ipv6 in a match-all class map.
so if you want to set dscp for ipv6 packet you have to configure:
class-map ipv6dscp
match protocol ipv6
policy-map set-dscp
class ipv6dscp
set dscp xx
