Has anyone got RTNA working with Cisco ASA firewalls? I have an ASA5512 running 9.1(5) which I've configured as follows:
flow-export destination <interface> <ip address> 2055
access-list global_mpc extended permit ip any any
match access-list global_mpc
flow-export event-type all destination <ip address>
service-policy global_policy global
When I enter the SNMP community into RTNA (version 10.8.0.5), I see the hostname of our ASA, and all the interfaces listed along with their current utilisation, but without anything in the "Flow Type" column. When I select any interface and click the "Start Flow Capture button", it gives me the error "NetFlow is not detected on the selected interface". I have confirmed with Wireshark that the NetFlow data is hitting my PC and with TCPView that NetFlowRealtime.exe is listening on port 2055/UDP. As per http://thwack.solarwinds.com/thread/51798#181807 I deleted the SNMP community and restarted, and I still saw the interfaces, but without the utilisation. I've tried graphing a 2801 router and this worked successfully, though I did set this up using NetFlow Configurator, which I can't do with the firewall because it doesn't support SNMP set.
