Issue:

customer sees lot of reboot in the flow statistic panel but he know that the devices are not rebooted frequently

Environment:
win2012 / NFA 9.3.6
Cause:

NFA considers that a device has rebooted when this device no more reply to the snmp polling and sysuptime value

no more increase in the netflow packets.

Resolution:

Install the NFA 9.3.7 version which contains a patch to take in count the netflow data received to identify the routers'reboot states .

(Netflow v9 Sequence Numbers will be also monitored instead only the sysuptime value)
