Posted on - by Joanna Buckley
I think I can safely assume that everyone knows the cautionary tale of the boy who cried wolf. If you don’t, the moral is the more you say something is wrong when nothing is wrong, the more likely it is no one will believe you when something actually is wrong.

Read moreDefining top talkers with Flexible NetFlow and AVC
Posted on - by Khalil Ismayilov
I was recently on a call with a customer who wanted to know which applications use the most bandwidth during working hours—i.e. their top talkers. This gave me a great opportunity to review a specific feature of Flexible NetFlow and AVC integration. I’ve decided to build a small lab with a simple network configuration where I could set up a couple of VLANs, a trunk communication between L2 and L3 devices, and couple of devices.
