I am working in the implementation of a call center with up to 120 agents based on Avaya MG8300. All the agents will use avaya soft phone and the switches are Cisco 2960.
I like to have some tips and advise to properly set up QoS in the Switches.
I think auto qos feature is designed to work with Cisco IP phones not third party.
Because all the agents will use soft phone I wouldn't assign QoS by physical port or VLAN, so how should I set the equipment to classify voice and data packets coming from the same device?
I will appreciate all assistance you can give me.
Assuming the Avaya is marking it's voice traffic as ef and signaling as either af31 or cs3:
mls qos map cos-dscp 0 8 16 26 32 46 48 56
class-map match-all RTP
match ip dscp ef
class-map match-all Control
match ip dscp 24 26
police 1000000 4096
int range fa0/1 - 48
service-policy input SoftPhone
wrr-queue bandwidth 10 20 70 1
no wrr-queue cos-map
wrr-queue cos-map 1 0 1
wrr-queue cos-map 2 2 4
wrr-queue cos-map 3 3 6 7
wrr-queue cos-map 4 5
On the uplinks, put this under the interface:
mls qos trust cos
Again, this is not knowing how the Avaya is marking the traffic. Are you going to be using voice vlans?
Please rate if this helped.
