*Cisco Wireless Controller authentication with ISE for both wireless users and device admin We deployed Cisco WLC and currently use the ISE/RADIUS to authenticate wireless users for network access. This is in a good working state right now.
*Network access before the authentication request is sent to ISE, Closed Mode provides zero access before receiving a response from ISE or a timeout occurs. Because no access was provided, no IP address was obtained, and a VLAN may be.
Cisco ISE is another option for authorizing users, enabling many additional business use cases. Meraki APs will pass necessary information over to Cisco ISE using MAC-based authentication and honor a Uniform Resource Locator (URL) redirect that is received from the Cisco ISE Server.
The purpose of this blog post is to document the configuration steps required to configure Wireless 802.1x authentication on a Cisco vWLC v8.3 using Cisco ISE 2.4 as the RADIUS server.
WLC ConfigurationDefine AAA Servers
*Login to the WLC WebGUI
*Click Advanced
*Navigate to Security > AAA > RADIUS > Authentication
*Click New
*Define the IP address of the RADIUS Server (ISE)
*Define the Shared Secret
*Ensure Support for CoA is Enabled
*Click Apply
*Navigate to Security > AAA > RADIUS > Accounting
*Click New
*Define the IP address of the RADIUS Server (ISE)
*Define the Shared Secret
*Click ApplyCreate WLAN
*Navigate to WLANs > WLANSs > WLANs
*Select Create New and click Go
*Define a Profile Name e.g. LAB_WLAN
*Define a SSID e.g. LAB_SSID
*Define an ID e.g. 1
*Click Apply
*Under the General tab, ensure the Status is Enabled and Security Policies is [WPA2][Auth (802.1x)]
*Under the Security tab, select AAA Servers
*Ensure the Auth Called Station ID Type is AP MAC Address:SSID
*From the drop down list select the previously defined Authentication and Accounting Servers
*Ensure Interim Update is selected
*Scroll down and remove LOCAL and LDAP, ensure only RADIUS is used for authentication
*Under the Advanced tab, tick the box for DHCP Addr. Assignment
*Under the Radius Client Profiling section, tick the box for DHCP Profiling and HTTP Profiling
*Click ApplyAP Groups
*Navigate to WLANs > Advanced > AP Groups
*Click Add Group
*Define a name for the group, e.g. LAB_GROUP
*Click Add
*Click the newly created AP Group
*Define a NAS-ID e.g vWLC
*Click Apply
*Click WLANs tab
*Click Add New
*Select the WLAN SSID from the drop down list, click Add
*Click the APs tab
*Select the AP(s) to add to the Group, click Add APs
NOTE – the AP(s) will now be reconfigured and rebooted
*Click <Back when completeISE ConfigurationAuthentication Policy
*Create or modify the Authentication Policy
*Create a rule to authenticate using PEAP/MSCHAPv2, named appropriately
Rule Name:-
MSCHAPv2
Antec fusion vfd. Conditions:-
Network Access-EapAuthentication EQUALS EAP-MSCHAPv2

When the user connects the AP MAC Address + SSID is sent in the radius packet, this can be used in the Authorization rule to distinguish users from the SSID they are connecting from. The first rule for Domain Admins uses the Called-Station-ID radius attribute with a regex to match the SSID the user is connected to.
In addition to using the Called-Station-ID radius attribute to determine the SSID the user is connected to, if the WLC/AP is Cisco we can use the attribute Airespace-Wlan-Id. For members of the Domain Users group we will use this value. It is important to note the value specified must equal the number of the SSID defined in the WLC SSID configuration.
For Domain Computers we will not require the computer can authenticate from a specific WLAN SSID, just that it is a member of the Domain Computers AD group.
Verification and Testing
With a wireless enabled device login as a user that is a member of the AD group Domain Users. From the ISE logs we can determine the user was matched against the correct Authorization rule and the conditions worked.

Logoff and login as a user that is a member of the AD group Domain Admins. From the ISE logs we can determine the user was matched against the correct Authorization rule and these conditions also worked.
From the detailed output we can determine the AD Group, the NAS-Identifier defined in the AP Group configuration and the Called-Station-ID.
From the WLC we can navigate to Monitor > Clients and determine the client properties. We can determine user2 associated to the correct SSID and used 802.1x authentication, with PEAP as the protocol. MAC-Based Access Control
It is critical to control which devices can access the Wireless LAN. MAC-Based Access Control can be used to provide network access control on MR series access points. With MAC-Based Access Control, devices must be authenticated by a RADIUS server before network access is granted on an SSID.
The Access Point (Authenticator) sends a RADIUS Access-Request to the RADIUS server containing the username and password of the connecting wireless device based on the association process. With MAC-based Access Control, the username and password combination is always the MAC address of the connecting device, lower case, without delimiting characters.
If a RADIUS policy exists on the server that specifies the device should be granted access and the credentials are correct, the RADIUS server will respond with an Access-Accept message. Upon receiving this message, the AP will grant network access to the device on the SSID.
If the RADIUS server replies with an Access-Reject, the device does not match an existing policy or the RADIUS server has a rule denying the client and the AP will not grant network access to the device.

*It is not an association method that supports wireless encryption. Communication between wireless clients and the MR is not encrypted and can be intercepted and viewed as clear text by “man-in-the-middle” devices using easily accessible wireless capture tools. Therefore clients will need to rely on upper layer protocols for encrypting traffic, such as SSL or IPsec, once a device has gained network access.
*Because the MAC address of the device is used as the authentication credentials, an attacker can easily gain network access by spoofing the MAC address of previously authenticated clients.
