It is indeed interesting to know how information can travel via Air. With all the Physics and a pinch of Magic, WiFi becomes an essential commodity.
Arista WiFi EAP-TLS with AGNI using RadSec and OneLogin as Identity Provider
802.1X has become one of the most used Authentication methods in WiFi in different verticals and industries for devices whose data and Intellectual Property (IP) needs to be protected. The basic framework used with this authentication is EAP which comes in different flavors. Based on different types of requirements and levels of protection, different flavors…
Arista WiFi WPA2-UPSK with AGNI using RadSec and OneLogin as Identity Provider
Arista Guardian for Network Identity (AGNI) is one of the Cloud-Native solutions which provides Identity based Access Control. This cloud based server uses Primarily RadSec for communication with the Authentication devices like WiFi APs (Access Points) and Switches. In this blog I try to explain how we can set up WiFi UPSK (Unique Pre-Shared Key)…
The Extension of 802.11ax – WiFi 6E
Looking at the trend of devices that are becoming mobile and/or are becoming WiFi capable, it is obvious that WLAN would need more bandwidth and user handling capabilities. There are studies and numbers already out showing a growing need for WLAN infrastructure and the efficient technology to accommodate the new devices and applications. These applications…
WPA3 Deep Dive
Continuing to the previous post wherein we discussed some theory about WPA3 and Dragonfly; in this post, I will try to explain WPA3 using packet captures analysis. The WLAN industry is making products easy to use and configure so I guess configuring WPA3 may not be an issue as it is a simple step of…
[Updated] Guest user-auth with ClearPass and Arista APs – Using CoA
In the previous twisted workflow where on receiving Radius Reject message leading to provide access to the WLAN may not look good when considering the accounting part of the authentication. To handle it in a better way, Arista APs can now support role-based capabilities which makes the understanding of the process authorization easy. Using these…
Power Save Mechanisms – 802.11ax
Power save is one of the important requirements for mobile devices. WiFi can drain the battery of a mobile device quickly. Hence in 802.11 networks power save management is achieved based on active and doze states of a mobile device. In the active state, the mobile device is communicating to the AP and in doze…
WPA3 and DragonFly (SAE)
Overview: WPA3 has brought in new advantages over WPA2 in order to overcome issues such as Offline Dictionary Attacks and provide advantages of forward Secrecy. This does look promising to secure existing WPA2 networks that are currently in use. In general, WPA3 doesn’t define new protocols but instead raises mandatory support for existing protocols that…
Third radio Connectivity tests with Arista APs.
For a WiFi Network administrator, it is a necessary task to keep checking the network health of the APs. Most of the management planes show the health of the AP which includes information like AP’s uptime, AP RF status, 802.11 authentications or association status, etc. Arista does the same by the tool called Cloud Vision…
802.11ax – OFDMA
OFDMA is currently gathering a lot of attention in the WiFi community. This is because of the demand for ever-increasing growth of mobile devices, internet, multimedia, and various other services. OFDMA based systems are capable of providing high data rates, efficient sharing of resources, and take advantage of multipath. Already proven its importance in other…
Should an existing WLAN network be upgraded to 802.11ax now?
802.11ax has definitely brought a lot of awesome features making communication more secure, efficient and fast. The type of features and updates in 802.11ax will for sure change the way WLAN works and has been operating till now. Although everything turns out to be good OR rather best with 802.11ax, the question always remains; when…
