section of the Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.3.
The incoming traffic is considered trusted by default. Only when the trusted boundary feature is enabled
Note
on an interface can the port enter untrusted mode. In this mode, the switch marks the DSCP value of an
IP packet and the CoS value of the VLAN tag on the Ethernet frame as "0".

Specify the matching criteria used to define a traffic class.
Create a traffic policy (policy map). The traffic policy defines the QoS policy actions to be taken for
each traffic class.
Apply the policy actions specified in the policy map to an interface, VLAN, or port and VLAN.
Descriptions
Configures the match criteria for a class map on the basis of the specified ACL.
Configures the match criteria for a class map to be successful match criteria for all
packets.
Matches a packet based on a Layer 2 class of service (CoS) marking.
Identifies a specific IP differentiated service code point (DSCP) value as a match
criterion. Up to eight DSCP values can be included in one match statement.
Identifies IP precedence values as match criteria.
Configures the match criteria for a class map on the basis of the specified protocol.
Descriptions
Configures traffic policing.
Configures traffic policing on the basis of a percentage of bandwidth available on an
interface.
Configures traffic policing using two rates, the committed information rate (CIR) and
the peak information rate (PIR).
Sets the Layer 2 class of service (CoS) value of an outgoing packet.
Marks a packet by setting the differentiated services code point (DSCP) value in the
type of service (ToS) byte of IPv4 or traffic class byte of IPv6 packet.
Sets the precedence value in the packet header.
Unconditional marking of one packet field based on another packet field.
Gives priority to a class of traffic belonging to a policy map.
Shapes traffic to the indicated bit rate according to the algorithm specified.
Provides a guaranteed minimum bandwidth to each of the eight queues.
Dynamic buffer limit.
Specifies the maximum number of packets a transmit queue can hold.
