classofservice traffic-class-group
This command maps the internal Traffic Class to an internal Traffic Class
Group (TCG). The Traffic Class can range from 0-6, although the actual
number of available traffic classes depends on the platform.
Use the no form of this command to return system (Global Config mode) or
interface (Interface Config mode) to the default mapping.
Syntax
classofservice traffic-class-group <trafficclass> <traffic class group>
no classofservice traffic-class-group
Parameter Description
Default Configuration
By default, all the traffic classes are mapped to TCG 0. In the default
configuration, all the Traffic Classes are grouped as one Traffic Class Group
and TCG0 is configured as weighted round robin.
Command Mode

User Guidelines
For a given Traffic Class, a value specified in Interface Config mode only
affects a single interface, whereas a change in Global Config mode is applied
to all interfaces. The Interface Config mode command is only available on
platforms that support independent per-port class of service mappings.
