add qos trafficclass= value flowgrouplist= values
Parameter
trafficclass Specifies the ID number of the traffic class you want to
modify. You can modify only one traffic class at a time.
flowgrouplist Specifies the new flow groups of the traffic class. The
new flow groups are added to any flow groups already
assigned to the flow group. Separate multiple flow
groups with commas (e.g., 4,11,12).

groups must already exist. Any flow groups already assigned to the traffic
class are retained by the class. If you want to add flow groups while
removing those already assigned, refer to “SET QOS TRAFFICCLASS”
on page 271.

add qos trafficclass=17 flowgrouplist=21
