Net Flow Difficulty

Patrick McHenry


I'm trying to send some netflow info to Solarwinds. This is the config I applied to my router but am still not able to see the device on the netflow page. Any ideas for troubleshooting?

ip flow-export destination 9995
no ip http server
no ip http secure-server
access-list 60 remark - Solarwinds only
access-list 60 remark - SNMP RO ACL
access-list 60 permit
access-list 60 deny   any log
cdp run

snmp-server community XXXXX RO 60
snmp-server location HQ

Solarwinds appears to be hitiing the router.

Standard IP access list 60

    10 permit (31113966 matches)

    20 deny   any log

Thanks, Pat.

You realize NetFlow export (to a NetFlow collector) is different from a NMS doing SNMP access?  It's also different from syslog server.  Although, of course, one server might support all 3, but is your SolarWinds server configured as a NetFlow collector?  If it is, any more NetFlow configuration on your router other than NetFlow collector's IP?

This is my config on SolarWinds.

Yes our Solarwinds server is configured for netflow and there are devices currently sending to it. I've looked at the configs of the routers sending to netflow but, don't see any difference. Is there someting missing in my config I have pasted? To be honest, I wasn't aware that netflow was not snmp. I though it was snmp on steroids.

Thanks, Pat.

Do I need to supply a source interface to the config?

Thanks, Pat.
