To increase the number of supported active flows, you should add ``dp_flows'' arg in config file ``memory'' section.

==== I want to have more active flows on the DUT, how can I do this?
After stretching TRex to its maximum CPS capacity, consider the following: DUT will have much more active flows in case of a UDP flow due to the nature of aging (DUT does not know when the flow ends while TRex knows).
In order to artificialy increse the length of the active flows in TRex, you can config larger IPG in the YAML file. This will cause each flow to last longer. Alternatively, you can increase IPG in your PCAP file as well.
