Enabling NetStream Aggregation Flow Statistics Collection on an Interface

Aggregation flow statistics can be exported only when you have enabled flow statistics collection on an interface.

Run the system-view command to enter the system view.
Run the interface interface-type interface-number command to enter the interface view.
Run the ip netstream { inbound | outbound } command to enable the NetStream function on the interface to collect statistics about aggregation flows.
By default, NetStream is disabled for aggregation flows.
