NetFlow Collector IPv6 Support

With the exhaustion of IPv4 addresses, the need to switch to IPv6 is inevitable and has been for many years. As your company makes the switch to IPv6, don’t forget NetFlow collector’s IPv6 support. I’m not only talking about the ability of your NetFlow collector to report on IPv6 conversations, but also the ability to collect NetFlow sent in IPv6 packets.

NetFlow Analyzer No Flows Received

NetFlow Analyzer No Flows Received

When you log into your NetFlow Analyzer, it may be shocking to find one of your core devices is saying “no flows received”.  I’ve seen this in support and know that it is important to have your devices sending NetFlow data to your collector at all times.  I’ve found that the best way to uncover the issue is to narrow down the variables and isolate the problem.  In this blog, I’d like to look at why flows are not being received by a NetFlow collector, by using a packet capture analysis tool, Wireshark.

HP 6600 NetFlow Support

HP 6600 NetFlow Support

Recently, I discovered that the HP 6600 Router Series has support for NetFlow. If you search for HP 6600 NetFlow Support, though, you don’t find much. This is because HP’s version of NetFlow is called NetStream (likely from their acquisition of 3Com). I first learned about this when I browsed HP’s website to see if they offered NetFlow/IPFIX support. After much searching, I found what I was looking for. Today, I want to help you configure your HP 6600 Routers to send flow data to your collector. Read more »

User Bandwidth Monitor

User Bandwidth Monitor

I often receive calls from system administrators who want to set up a user bandwidth monitor. The admins aren’t always clear about what they mean by that, but by using NetFlow and IPFIX data it’s possible to create a variety of reports that could satisfy management’s demands for easily accessible insight into user activity. It’s simple enough to generate reports that show total bandwidth usage for the network’s devices. But we can also create reports that are fine tuned to monitor the bandwidth usage of discrete groups of users or of particular website URLs, so that management can keep abreast of what employees are doing and whether that use complies with enterprise network usage policy. I’m going to setup a couple of reports, then save them as gadgets on a dashboard so that managers will have quick and easy access to timely information about user activity.
