Hi all,
i'm facing a weird problem with asa5520x (Version 9.6(4)10 ) in TRANSPARENT mode and Netlow collector (manage engine ).
I had to move the configuration of my transparent firewall from vlan mode to subinterface with portchannel.
Since then i receive no flow for the subinterface and/or etherchannel interface ( i receive flows for phisical port insted )
i wrote to manageengine and they say there is no particular conf on their software...and i should be able to see all the traffic if the ASA is correctly configured.
ASA is sending flows for other interface ( phisical and for the management )so everithing is ok from the configuration point of view.
Manageengine said that if i don't see the subinterface traffic...it means ASA do not send flows for that specific traffic.
As far as i know..asa Netflow is supported by ASA in transparent mode....but i could be wrong.
any suggestion about this issue?
the asa conf is quite straighford....
