Example
In the following example, the XP will export 91 flow records when the interval timer expires.
Shown here, 4 transmissions result.
Asynchronous and Periodic Exportation
If the interval timer expires before NetFlow fills the export buffer with inactive flows, NetFlow will
fill the remaining space with active flows. For example, consider a case where two expired flows
queue for export when the interval expires. If twenty-eight or more flows are active, the first
interval transmission will appear as follows:
Header Flow 1 Flow 30
. . .
Header Flow 31 Flow 60

Header Flow 61 Flow 90
