Netflow Export suddenly stops working

Christian_Masop — Mon, 26 Mar 2018 05:40:24 GMT

I've configured and running Netflow Export on my 4600 appliance (R77.30 Take 292). Since last week it suddenly stopped exporting any data.

fw ctl zdebug drop shows no droped data for the configured collector and fw monitor shows no udp traffic to the configured port.

I've also tried to remove the collector and add it again, no change.

What can be wrong?

Just a hunch, but it's possible a reboot may be necessary to get Netflow working again.

I would engage with the TAC on this so we can get to the bottom of it, though.

Hi Dameon,
that what I've feared of I'd see if I can reboot it during today's maintenance window.

Thanks!

Maintenance window has come and passed by without time for a reboot

But... as sudden as it stopped sending Netflow data as sudden it started again... funny.
