From the 3560 command reference:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3560/software/release/12.2_25_see/command/reference/cli1.html#wp5046030
mls qos
Use the mls qos global configuration command to enable quality of service
(QoS) for the entire switch. When the mls qos command is entered, QoS is
enabled with the default parameters on all ports in the system. Use the no
form of this command to reset all the QoS-related statistics and to disable
the QoS features for the entire switch.
mls qos
no mls qos
Syntax Description
This command has no arguments or keywords.
Defaults
QoS is disabled. There is no concept of trusted or untrusted ports because
the packets are not modified (the CoS, DSCP, and IP precedence values in the
packet are not changed). Traffic is switched in pass-through mode (packets
are switched without any rewrites and classified as best effort without any
policing).
When QoS is enabled with the *mls qos* global configuration command and all
other QoS settings are set to their defaults, traffic is classified as best
effort (the DSCP and CoS value is set to 0) without any policing. No policy
maps are configured. The default port trust state on all ports is untrusted.
The default ingress and egress queue settings are in effect.
