Command
Purpose
classofservice traffic-
class-group
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.
traffic-class-group max-
bandwidth
Specifies the maximum transmission bandwidth limit for 
each TCG as a percentage of the interface rate. Also 
known as rate shaping, this has the effect of smoothing 
temporary traffic bursts over time so that the transmitted 
traffic rate is bound.
traffic-class-group min-
bandwidth
Specifies the minimum transmission bandwidth 
guaranteed for each TCG before processing frames from 
lower numbered TCGs on an interface.
traffic-class-group strict Activates the strict priority scheduler mode for each 
specified TCG.
traffic-class-group 
weight
Specifies the scheduling weight for each TCG. The 
scheduler attempts to balance the traffic selected for 
transmission from the TCGs such that, when the switch is 
congested, traffic is selected from the round robin 
configured TCGs in proportion to their weights.
