Configuring Auto-QoS
•
•
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.
Global Auto-QoS Configuration
Table 1-5 Generated Auto-QoS Configuration
Description
The switch automatically enables
standard QoS and configures the
CoS-to-DSCP map (maps CoS
values in incoming packets to a
DSCP value).
The switch automatically maps
CoS values to an ingress queue
and to a threshold ID.

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.
