Long story short, we are cleaning up, optimizing and introducing new QoS policies within our WAN. We are a large enterprise, with a mainly Cisco UC VOIP environment, however we have some one offs that are Avaya.
The original class map was:
class-map match-any VOICE-class
match protocol cisco-phone-audio
based on NBAR. Obviously with Avaya phones this will not work, and you will have 0 matches thus not prioritizing your voice traffic.
Policy map:
class VOICE-class
priority 1900
set ip dscp ef
I adjusted the class map to match on an ACL, rather than NBAR. I figured being as the Avaya gateways were local the voice traffic would always source from one of the gateways.
New class map:
class-map match-any VOICE-class
match access-group name AVAYAGateway
The ACL would consist of the addresses of the Avaya gateways.
This change has worked, we now see matching traffic on the policy map, and traffic is being prioritized as it should be.
My question is, is this the best way to configure this, or is their a cleaner, more optimal way of doing this for Avaya?
Thanks in advance!
