Chapter 1 Configuring QoS
Configuring Auto-QoS
• A switch is enabled with QoS, these guidelines take effect:
– If you configure the interface for conditional trust on a voice device, only the legacy auto-QoS
VoIP configuration is generated.
– If you configure the interface for conditional trust on a video device, the enhanced auto-QoS
configuration is generated.
– If you configure the interface with classification or conditional trust based on the new interface
auto-QoS commands, enhanced auto-QoS configuration is generated.
• Auto-QoS migration happens after a new device is connected when the auto qos srnd4 global
configuration command is enabled.
Note If an interface previously configured with legacy auto-QoS migrates to enhanced auto-QoS, voice
commands and configuration are updated to match the new global QoS commands.
Auto-QoS configuration migration from enhanced auto-QoS to legacy auto-QoS can occur only when
you disable all existing auto-QoS configurations from the interface.

The switch automatically enables
standard QoS and configures the
CoS-to-DSCP map (maps CoS
values in incoming packets to a
DSCP value).
Switch(config)# mls qos
Switch(config)# mls qos map cos-dscp
0 8 16 26 32 46 48 56
Switch(config)# mls qos
Switch(config)# mls qos map cos-dscp 0
8 16 24 32 46 48 56
The switch automatically maps
CoS values to an ingress queue
and to a threshold ID.
