QoS configuration witch DSCP and COS

[toro_dlp]

I'm working with LS 6212 switch. And I want to set the priority all VoIP packets.
All VoIP packets have a mark DSCP = 46 and would like to establish with CoS = 7.
I have the same settings on the new switches (6250, 6400, etc.) with the qos and policy rules. But here is not the same.
The only way I would like is: from DSCP = 46 >> configure COS = 7.
I proposed this (work?):
------------------
qos advanced
ip access-list AL-V
permit ip any any dscp 46
exit
class-map CM-V
match access-group AL-V
exit
policy-map PM-V
class CM-V
set cos 7
exit
exit
---------------------

Hi,
it's a long time ago.... but I remember that you have to use two ACE per ACL. The following is an example:

qos advanced
ip access-list AL-V
permit ip any any dscp 46
exit
ip access-list OTHER
permit any any
exit
class-map CM-V
match access-group AL-V
exit
class-map CM-O
match access-group OTHER
policy-map PM-V
class CM-V
set cos 7
class CM-O
exit
exit


But why do you would like to do this. All switches do use priority also in L3 (dscp). No need for L2 (802.1p-COS).

Thanks Silvio. Sorry for my delay.
The packets with voice are marked with dscp=46. This category has priority q3. It´s the same with CoS=7 (priority queue=3) by default.
It´s not my configuration. I only have to implement this at this site. All the site on the network have the same.
I think some switch on the network haven´t got L3. Therefore we have packet with voice marked in all the path.
