[cisco-voip] COS on Cisco 3750 - help please

Hi

You can make a map cos-dscp command, like this:

mls qos map cos-dscp 0 46 8 16 26 32 48 54

With this, you modify  the mapping in your core switch to router.

Hi all

I'm having a problem with voice quality going over the WAN.  We use a
2801 on each end.  Someone suggested that there might be a issue with
COS.  I thought by default Cisco tags all voice traffic as COS 5.  AT&T
is looking for COS 1.  Am I wrong about Cisco being tagged as COS 5?  If
not, then how do I change the 3750 to tag the voice as COS 1 to match
AT&T?

Thanks

Russ
