VoIP QoS for Site-to-Site Tunnel

Question

Hi all,
I need some help with setting up QoS for VoIP between two Cisco ASA 5505 with Site-to-Site VPN.
There is no need for bandwith reservation, only DSCP 46 (EF) should be highest and DSCP 26 second highest queue and the rules should only apply to a site-to-site VPN.
Usually i try to configure the ASAs via ASDM and found out in the Cisco Documentations how to setup QoS for the DSCP bits with a Service Policy and how to set up QoS for a Site-to-Site VPN (Service Policy Rule -> Traffic Match). But how do i configure the QoS for a DSCP bit to only apply to a Site-to-Site Tunnel? And how do i configure different priorities for the two DSCP bits, is this defined by the order of Service Policies?
The QoS has to be enabled on both ASAs for the inside interface?
Thanks in advance
Tobias

Answer 1

Hi Collin,
ok so from the document i think this has to be added on both ASAs to prioritize DSCP 46. Could you have a quick look if this is all i need?
class-map voice_traffic
match dscp ef
class-map data
match tunnel-group <Tunnel Name>
match flow ip destination-address
policy-map voice_policy
class voice_traffic
  priority
class Data
 police output 200000 37500
service-policy voice_policy interface outside
But there is still the question how two configure another DSCP bit for priority 2, I could not find out how this is done, neither CLI nor ASDM. Any ideas?
