This has been a topic of conversation at work between a few of us, so I'm interested in the feedback.

Sent from my phone, apologies for any typos.

The QoS SRND states that the "auto qos voip" command adds the following config to the router:

C2970(config)# mls qos
C2970(config)# mls qos map cos-dscp 0 8 16 26 32 46 48 56

Earlier in the SRND, around page 40, it says that the old marking for audio signaling was AF31 (26). That is the same DSCP marking listed above.

As part of our "best-practice" scenario, should we be changing the command to consider audio signaling as CS3 (24)? The command would need to be modified:

C2970(config)# mls qos map cos-dscp 0 8 16 24 32 46 48 56

Is this true?  Otto, can you weigh in on this one?

Thanks!
