[cisco-voip] Auto-QoS ?

[Carter, Bill]

AutoQoS on the switches still maps COS 3 to DSCP AF31(26), when current
SRND and CM installations set call control to DSCP CS3(24).  I run
autoqos on the switches then adjust the map.

I would agree on the Router-side.. but for the switches, it is far more
likely to have positive results than the manual method...
especially without years of experience configuring your queues...

To be honest, the auto-qos dumps config into the switch that is, A:
Cisco TAC supported, B: Likely to work great and C: easy.

Why wouldn't you use it? Unless you have a lot of SNA traffic or
something...
