I have been looking into this solution as an interim to solving the problem. Anyone have any insight as to what could be causing this problem or what to look for. Won't be able to call in for support for a week or 2.

I decided to use fprobe (software) with a linux based server and attached it to the router on a mirrored port. The fprobe had to have minimal configuration so it knows what traffic is internal/external. It then emitted the Netflow packets just as any router would to our collector (flow-tools). This doesn't answer your question, but it is a workaround that I used, and still use today. -----Original Message----- From: marc slice [mailto:[email protected]] Sent: Thursday, March 05, 2009 10:38 AM To: Enterasys Customer Mailing List Subject: [enterasys] Matrix N Series Netflow Numbers not matching snmp totals problem On a Matrix N series we currently have netflow turned on for the ports to our ISP ports (ge.1.29 and ge.1.30) and our public vlan ports (ge.1.2,ge.1.11,ge.1.17). Our current reading of the bytes per second through snmp on our switch is equal to our isp's numbers yet each and every netflow collector we have tried is reporting less. Mainly our inbound numbers are off by 40-50% yet the outbound is only 5-10% off on ge.1.29-30. Also we have tried using both Netflow v5 and v9 and used collectors on different servers directly plugged into the matrix switch. We have tried flow-tools, ntop, scrutinizer, solarwinds orion NPM with NTA and one or 2 others but all report the same difference. Running the latest firmware. Anyone have any insight or have the same problem? We need to account for the traffic by IP and were relying heavily on this working. --- To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected] --- To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected] --- To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected]
