[cisco-voip] CCM and QoS

[Jordi Riba (Europe)]

Hi All,

 

I would like anyone to answer these QoS configuration doubts, if it's possible?

 

I have a Headquarters office and some branch offices:

 

-          Headquarters:

o   CCM connected to a 6500 Switch port  à What should I use?

§  Mls qos trust cos    ß I'm using this one

§  Mls qos trust dscp

 

o   Service provider Router connected to a 6500 Switch port (Layer 2 connection) à What should I use?

§  Mls qos trust cos

§  Mls qos trust dscp  ß I'm using this one

 

o   MGCP Gateways connected to a 6500 Switch port  à What should I use?

§  Mls qos trust cos ß I'm using this one

§  Mls qos trust dscp  

 

o   Switch connected through trunk ports à What should I use?

§  Mls qos trust cos 

§  Mls qos trust dscp  ß I'm using this one

 

-          Branch Offices:

o   H323 Gateways connected to a 3560 switch port àWhat should I use?

§  I'm using "auto qos voip trust"

 

o   Service provider Router connected to a 3560 Switch port (Layer 2 connection) à What should I use?

§  I'm using "auto qos voip trust" but changing the line "mls qos trust cos" to "mls qos trust dscp"

 

Does CCM automatically mark signaling traffic to DSCP 24? Should I configure anything on Enterprise Parameters? I think it's not necessary to do anything but I'm not sure...

 

Any help will be  appreciated.

 

Thanks,
