Fair Queue in an MQC Class in 12.4T

12.4t documentation on Fair Queue in an MQC Class This feature provides a fair-share of the bandwidth among the flows within any traffic class that has fair queuing enabled. You can apply the fair-queue command to a user-defined class as shown in the following example: policy-map p1 class c1 bandwidth 1000 fair-queue

Fair-queue was supported pre 12.4, it runs on my 12.2 aswell... what is cisco trying to say?
