Cisco ISE – Basic 802.1x With WindowsPart Three – Adding Network Devices (Authenticators)
KB ID 0001077 Problem Back in Part Two we configured the specific 802.1x policies in Cisco ISE. Remember with 802.1x it is a three tier system there is a supplicant, (a machine that wants to authenticate), the Authenticator, (the device the supplicant connect to, in our case a switch), and finally an Authentication server (Cisco ISE). Below I will add our switch into ISE, as a RADIUS device and create some groups, and locations for...

Windows Server Setup RADIUS for Cisco ASA 5500 Authentication
KB ID 0000685 Problem Note: The procedure is the same for Server 2016 and 2019 This week I was configuring some 2008 R2 RADIUS authentication, so I thought I’d take a look at how Microsoft have changed the process for 2012.

Solution Step 1 Configure the...
