Read about virtual routing first before reading this post.  VRF aware Netflow is available in Scrutinizer since v7 and in IOS starting with 12.4(11)T, however I also saw in some documentation that support for VRF input was added in 15.0(1)M. This is of course via Flexible Netflow. You can set the input VRF as a key field in the NetFlow record, then use the VRF ID to filter reports based on that VRF in scrutinizer.

I thought I’d post about our new Citrix AppFlow reporting on the NetScaler IPFIX export. When we first started working with AppFlow I was naturally curious if it was an IPFIX or NetFlow technology.  We quickly learned that it is 100% compliant with the emerging IPFIX reporting standard so don’t go looking for NetScaler NetFlow.  This new export is a great addition to your network monitoring efforts.

Are you looking for Catalyst 3750 NetFlow Support?  Unless you own the X model (i.e. Catalyst 3750X) you will need to span a port to an nBox, a SonicWALL in bridge mode or similar.  The Catalyst 3750X NetFlow support is only available if you have invested in the 3KX module.  Without the 3KX, this switch only supports Smart Logging and Telemetry Flexible NetFlow exports.

Over 100 SonicWALL field people have been brought up to speed on the IPFIX capabilities of their next generation firewall.  This includes training on configuring SonicWALL IPFIX and NetFlow.

“As a Sonicwall system engineer, I’d have to say the level of support and rich reporting Scrutinizer provides to SonicWALL customers is phenomenal. So far, Scrutinizer is the only product on the market to report on all the unique template data we export via IPFIX. For example, Sonicwall is able to provide insight to actual users, applications (not just port based ones), urls, IPS events, and tons more via IPFIX. This functionality really helps network admins with regards to troubleshooting, reporting, and capacity planning. Further, Scrutinizer provides additional situational awareness of securtiy and network events with the Flow Analytics module.” Rob Andrews – SonicWALL Systems Engineer.
