Disable RRM? Aint Nobody Got Time for That!

Radio Resource Management (RRM) has been a hot topic as of late. This is the technology wireless networks use to maximize performance and adapt to interference by automatically configuring optimal radio settings based on the information radios receive from the wireless environment. Many Enterprise WLAN Professionals have been blogging and providing webinars recommending to disable this technology and instead statically configure...

802.1X Authentication Overview

First things first. It’s 802.1X, not 802.1x or 802.11x. Now that we have that straight, let’s move on. 802.1X is an Institute of Electrical and Electronics Engineers (IEEE) standard for port based network access control. 802.1X provides a framework for authentication and authorization as well as dynamic encryption key management for over the air encryption. With 802.1X, all traffic with the exception of authentication...

EAP-PEAP – A Closer Look

In the 802.1x Authentication Overview blog we established that EAP is layer 2 protocol used within the 802.1X framework to validate users and devices. Further that EAP is very flexible in that there are many different flavors of EAP or EAP methods available. Some are proprietary such as Cisco LEAP while others are standards-based such as EAP-TLS. Some provide mutual authentication while others do not. Some require both server and...

EAP-PEAP – Certificate Requirements

EAP-PEAPv0 (EAP-MSCHAPv2) requires a server certificate be installed on the RADIUS server in order to establish a secure TLS tunnel. Client computer and user certificates are not required as EAP-MSCHAPv2 is password-based. If Mutual Authentication is configured, the server certificate must be trusted by the client. This will require the CA certificate be installed on the client. See Mutual Authentication below for further information....

SDN and Wi-Fi Part 1 – SDN Background

The purpose of this blog is to define what Software-defined Networking (SDN) is and to start a dialogue around what this could mean for Enterprise Wireless Local Area Networks (WLANs). The first part of the blog involves defining SDN, what is driving it, what the benefits are, how it impacts us today and how it will impact us in the future. The final phase involves starting a dialogue around what this does and could mean for...

SDN and Wi-Fi Part 2 – SDN in Enterprise Wi-Fi

To date, the SDN discussion has been largely focused on the data center and wired networks. As enterprises move to virtualization and the cloud, they see that the configuration of conventional networks are time-consuming and error-prone. A virtual server might be created in minutes, but changing the underlying network infrastructure might take days or weeks. SDN has emerged to solve this problem for data center and wired networks the...
