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.

Today I’ll cover the importance of VoIP DSCP prioritization when NetFlow reporting.  We have 3 employees that work remotely in Central Maine, Pennsylvania, and Florida.  They all have Cisco routers and are exporting VoIP data to our NetFlow Analyzer server.  Read the Cisco Medianet Deployment Guide to learn more about setting this up.

It’s no secret the BYOD (Bring Your Own Device) revolution is in full swing, and you need to know how to monitor iPAD HD traffic on your corporate network. Long gone are the days where network administrators can police employees based solely on their desktop computer traffic. Cubicles are filled with 4 generations of iPhones, a variety of new e-readers, and now the new iPad HD / iPad 3.  BYOD network traffic analysis is of paramount importance.

Did you know that you can find quality of service (QoS) information in NetFlow? Knowing what quality of service your crucial network traffic gets can either make or break an efficient infrastructure. Due to its importance, certain traffic may be given a higher priority. Crucial business applications, for example, need higher priority than normal traffic, while social networks can receive low priority. Is there a way to easily find this information? Absolutely!

Today I’m going to discuss how to run some of the common reports in our NetFlow and IPFIX analyzer. Our NetFlow and IPFIX analyzer has the ability to report on all versions of NetFlow, sFlow, IPFIX and everything in between. If you’re new to the product, you might want to check out Cisco’s Introduction to NetFlow our NetFlow configuration guides to help you get started.

We spent some time awhile back building some host baseline logic for a future Flow Analytics release. If you’re not familiar with the term “host baseline”, it is a history of an IP node’s historical traffic behavior. Items that go into this communication baseline are behaviors observed in a specified time frame.

What a year so far!

You know the old saying “Time flies when you’re having fun”? Here at Plixer, our developers are so freakishly passionate about creating the NetFlow architecture of the future, the years seem to pass us by like a blur.

The hard work is really paying off! Not only were we the first company to receive Cisco certification within the Systems Management technology category but, we are proud to announce that last week we won the 2011 Golden Bridge Award for NetFlow innovations!These industry and peer awards from Golden Bridge are the world’s premier business recognition program. This award is a huge accomplishment for such a passionate group of employees. To top it all off, Cisco sent us Medianet T-Shirts!

With Cisco predicting by 2013 91% of all network traffic will be voice/video streams, we’ve been spending a significant amount of time focusing on the development of the many new Cisco Medianet performance monitoring reports. Scrutinizer v9.0 is just around the corner, it will be exciting to get feedback on all of the new reports we have built for Cisco Smart Logging and Telemetry, Cisco TrustSec, Performance Routing, Performance Monitoring and of course all of the new SonicWALL IPFIX support.

What is MediaNet?
Medianet is an intelligent end-to-end network that combines video technologies in the business, home and service provider networks. More than just higher bandwidth, it optimizes video and rich media traffic. Our solution was the first to report on the new metrics Cisco imbedded into Flexible NetFlow templates. Network traffic analysis with the advanced filtering in our NetFlow Management solution is further proof that our software provides the very best in NetFlow reporting. Read more »

Cisco Performance Routing (PfR) and NetFlow
PfR was well defined by Samuel Yee: “For most medium-to-large networks, you would usually have more than 1 ISP to connect the enterprise network to all the remote sites. Traditional routing (such as OSPF, BGP etc) could route network traffic through a preferred path or load-balance among different paths. It can also automatically change path when a link is dead. For many companies however, this still isn’t good enough.

Smart Logging Telemetry (SLT) is one of the latest NetFlow v9 exports from Cisco. This new export is very unique because the data in the flows isn’t just used for traditional NetFlow reporting such as top hosts or top applications.  The hardware (e.g. Catalyst 3XXX) supporting this technology is actually helping to secure today’s networks by performing a type of network behavior analysis on the traffic trying to traverse the switch fabric.
