or shared) on the egress queues mapped to the port.	Switch(config)# mls qos queue-set output 1 threshold

If you entered the auto qos voip trust command, the switch	Switch(config-if)# mls qos trust cos
automatically sets the ingress classification to trust the CoS	Switch(config-if)# mls qos trust dscp
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.
If you entered the auto qos voip cisco-phonecommand, the	Switch(config-if)#mls qos trust device cisco-phone
switch automatically enables the trusted boundary feature,
which uses the CDP to detect the presence or absence of a
Cisco IP Phone.
