COS fpr sure.
Phones mark COS & DSCP but only remark COS, so if you want tp extend the
trust border, you have tp trust COS.

Subject: MLS QOS
Hi all,
I got the below questions to clarify.
1) When a cisco VoIP phone is connected to a switchport, which is better?
mls qos trust dscp or mls qos trust cos?
2) The cisco phone will mark cos or dscp value or both? If mls qos trust
cos is use, must i map the cos 5 to dscp 46 manually?
