Configuring Auto-QoS
The switch automatically configures the egress queue buffer
sizes. It configures the bandwidth and the SRR mode (shaped
or shared) on the egress queues mapped to the port.
Switch(config)# mls qos queue-set output 1 threshold
1 138 138 92 138
Switch(config)# mls qos queue-set output 1 threshold
2 138 138 92 400
Switch(config)# mls qos queue-set output 1 threshold

If you entered the auto qos voip trust command, the switch
automatically sets the ingress classification to trust the CoS
value received in the packet on a nonrouted port by using the
mls qos trust cos command or to trust the DSCP value
received in the packet on a routed port by using the mls qos
trust dscp command.
Switch(config-if)# mls qos trust cos
Switch(config-if)# mls qos trust dscp
If you entered the auto qos voip cisco-phone command, the
switch automatically enables the trusted boundary feature,
which uses the CDP to detect the presence or absence of a
Cisco IP Phone.
Switch(config-if)# mls qos trust device cisco-phone
