Richard,
I think you re remarking the packets

Objet : DSCP on router

Hi group,

I have a question regarding packet marked as DSCP of 5 for voice.

If a voice device is attached to a switchA and switchA is connected to the RouterA. And there is no configuraration done on the the switchA and RouterA and the Voice device is sending packets marked as DSCP of 5,

Q) Is RouterA going to see those packets as DSCP 5 or they will be remarked to 0 ? (Switch A is regular 2950XL switch with no QoS)

Thanx in advance.

Tom
