Description (partial)

An "export storm" may be observed with cFlowd enabled on a XE SDWAN device. If QoS is configured outbound on the WAN interface, this may lead to queue drops, depending on the BW configured in the shaper.

cFlowd and DPI are enabled and a burst of traffic due to template export is seen at the template export interval.
