Using Cisco Application Visibility and Control (AVC), network administrators can manage network application performance by setting up a wireless policy to prioritize, control, and bring visibility to the BYOD applications traversing their network.

There are many challenges IT managers face on a daily basis. As the number of user devices and the business, personal and collaborative applications continue to grow, these challenges only make the job of an IT manager harder.

Today’s networks support a mixed use of guests, employees and vendors. Without classifying and prioritizing applications on the network, employees risk losing productivity and response time to critical applications that they use.

Imagine what goes through the mind of an IT administrator who is responsible for getting a handle on device and application growth and usage on their network:

• Is a guest downloading movies using Bit-Torrent – in other words, stealing valuable airtime away from my mission-critical applications?
• What are my top users and applications?
• Can I prioritize business-class applications and de-prioritize the applications such as Netflix?
• Do I need more Access Points?

So how is Cisco AVC going to help on your wireless network access points?

High volume NetFlow Collection usually can’t be attained by simply placing the NetFlow collector on beefier hardware. It requires understanding of the protocol, the preprocessing necessary to meet the demands of the front end, tweaking memory, optimizing database settings and of course powerful hardware.

Application Performance Monitoring needs to evolve from a Network Map to an Application Map.  It is amazing to me that most companies do not have a map of the applications that their business depends on.   When application performance is crawling, the network is often the first suspect.  I think the reason for this is partially because the network is the only thing documented.  Everyone knows that the network isn’t always at fault when it comes to poor application performance.  Lets fix this perception problem by starting off where the existing documentation ends.

One of the most fun yet scariest parts of being an entrepreneur is making predictions.  If your forecast is correct, hopefully it will be good for your company.  If you are wrong, you hope no one notices.  In 2009 I posted a blog titled OMG, the Internet is overloaded! where I discussed application recognition and its importance in the role of prioritizing traffic.  In the post I stated “Due to the fact that many applications use the same ports, application recognition is no simple process (e.g. Skype ‘VoIP’ looks like BitTorrent ‘data’).  My guess is that accurate application awareness is a highly dynamic problem necessitating frequent updates.”  Today, several vendors now perform Deep Packet Inspection (DPI) to monitor a series of packets to identify layer 7 applications. Cisco Application Visibility and Control uses NBAR to serve just this purpose. Below I’ve listed a few companies that utilize DPI to identify layer 3 applications:

In this blog I will be discussing how to configure Cisco 6500 Sup2T NetFlow. The Cisco 6500 Supervisor Engine 2T exports Flexible NetFlow, so your old Cisco 6509 NetFlow configuration will no longer be compatible with this setup.

I run into a lot of unique hardware working in technical support; as a result I want to write about Cisco ASA NetFlow and VPN support. Recently, I have received questions from customers wanting to monitor their VPN traffic using NetFlow. This blog will briefly cover what VPN is, and how I used our network traffic monitor for Cisco ASA VPN reporting. Read more »
