Configuring Auto-QoS
•
When you enable auto-QoS by using the auto qos voip cisco-phone or the auto qos voip trust interface
configuration command, the switch automatically generates a QoS configuration based on the traffic
type and ingress packet label and applies the commands listed in
Table 28-5 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.
The switch automatically maps CoS values to an egress queue
and to a threshold ID.

28-20
When you enter the auto qos voip trust interface configuration command on a port connected to the
interior of the network, the switch trusts the CoS value for nonrouted ports or the DSCP value for
routed ports in ingress packets (the assumption is that traffic has already been classified by other
edge devices). The switch configures the ingress and egress queues on the port according to the
settings in Table 28-3 and
