QoS on VPN Link

Unanswered Question

I'm having an issue with a couple phones over a VPN link. I have QoS on an ASA 5505 on the remote site and on the ASA5510 at the head end.

class-map Voice1

match dscp ef

match tunnel-group


policy-map qos

class Voice1


service-policy qos interface Outside

This is what my qos config looks like on each ASA. Does this look correct? Also I'm assuming I need to also prioritize on the inside interface?

Any help would be appreciated.

Sorry what I meant is I'm trusting the marking coming off the phone which is ef correct?

The RTP packets from the IP phone carry a DSCP value of EF but it is very much possible that along the way, this is rewriiten.

So as long as you are sure that the traffic has been properly marked and trusted along the path, it is fine
