WLC 4402-50 with ACS 3.3

Unanswered Question


We want to use ACS to authenticate an ssh or http connection to a WLC 4403-50 4.2.99 using TACACS+. On our ACS 4.2 test server it works fine. Configured identically on an ACS 3.3 appliance we are not able to log in although we do see a successful login in the Passed Authentications report withing ACS.

Is there an incompatability between the WLC 4402-50 with ACS 3.3?

The Cisco Secure Access Control Server (ACS) provides authentication, authorization, and accounting (AAA) services for users of the wireless network.

It is also possible to employ a WLC controller strategy that uses an N+1 approach. When using N+1 architecture, each WLC is configured with a WLC that is designated as a backup WLC in the event of a failure. This controller is not used until there is a failure event upon which all APs using the failed controller switch to the backup WLC. This cost-effective approach provides a high level of availability in the event of a single WLC failure scenario.
