2811 QoS in ATT MPLS

[asafayan]

We upgraded our infrastructure to Cisco 2811s and are now supporting voice services at our branch sites.  Previously, the branch site routers didn't support QoS so we performed QoS based on anything originating from our Voice  subnet 172.16.x.x.   Our WAN provider is ATT MPLS service and ATT  provides for 3 class of service categories as follows:

COS1 - Voice
COS3 - Data
COS4 - scavenger

I'm looking for best practice configuration guidance that would provide  proper QoS on their 2811 routers at our branch sites.  These Customer  Equipment routers will then connect to the ATT Provider Equipment  routers in ATT MPLS cloud.

TIA

Hi Amir,

of course the final configuration depends on your needs and constraints (ex. the bandwidth the provided guarantees for each class), so there's no easy answer to your inquiry.

The best thing you can you is to start reading the Configuration guide found here:

http://www.cisco.com/en/US/partner/docs/ios/qos/configuration/guide/12_4/qos_12_4_book.html

regarding QoS on the 12.4 IOS train.

Should you have more specific doubts or concerns just raise them and I can try sorting them out.

Regards,

Antonio
