Nested Traffic Classes
The MQC does not necessarily require that you associate only one traffic class to one traffic policy.
In a scenario where packets satisfy more than one match criterion, the MQC enables you to associate multiple
traffic classes with a single traffic policy (also termed nested traffic classes) using the match class-map
command. (We term these nested class maps or MQC Hierarchical class maps.) This command provides the
only method of combining match-any and match-all characteristics within a single traffic class. By doing so,
you can create a traffic class using one match criterion evaluation instruction (either match-any or match-all)

Purpose
Configures the exponential weight factor for the
average queue size calculation for the queue reserved
for a class.
Configure the WRED parameters for a particular IP
Precedence for a class policy in a policy map.
Specifies the name of a traffic policy used as a
matching criterion (for nesting traffic policies
[hierarchical traffic policies] within one another).
Sets the cell loss priority (CLP) bit when a policy
map is configured.
Sets the Layer 2 class of service (CoS) value of an
outgoing packet.
Marks a packet with a discard-class value.
Marks a packet by setting the differentiated services
code point (DSCP) value in the type of service (ToS)
byte.
Changes the discard eligible (DE) bit setting in the
address field of a Frame Relay frame to 1 for all
traffic leaving an interface.
Designates the value to which the MPLS bits are set
if the packets match the specified policy map.
Sets the precedence value in the packet header.
Sets a QoS group identifier (ID) that can be used later
to classify packets.
Shapes traffic to the indicated bit rate according to
the algorithm specified.
