Enabling NetStream Original Flow Statistics Collection on an Interface

IPv4 original flow statistics can be exported only if flow statistics collection is enabled 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 IPv4 flows.
By default, NetStream for IPv4 flows is disabled on the interface.
