The class maps are intended to identify control and data (bearer) voice traffic for either an Layer 2 or
Layer 3 interface.
The 2 Input policy maps, one for matching DSCP and one for matching COS, where DSCP and COS are
set to an assigned qos-group used in outbound policy-maps are as follows:
policy-map AutoQos-VoIP-Input-Dscp-Policy
class AutoQos-VoIP-Bearer-Dscp
set qos-group 46
class AutoQos-VoIP-Control-Dscp26
set qos-group 26
class AutoQos-VoIP-Control-Dscp24
set qos-group 24
! Note: For COS, Control traffic only has a single COS value of 3 (versus DSCP which has 2
values to match). So, only 2 class-maps instead of 3 like above.
policy-map AutoQos-VoIP-Input-Cos-Policy
class AutoQos-VoIP-Bearer-Cos
set qos-group 46
class AutoQos-VoIP-Control-Cos
set qos-group 24
