Cisco ACS Policy Decisions Based on SSID Name

If you're using an authentication server (such as Cisco's ACS) to make policy decisions about wireless users, there may be times when you'd like to make a decision based on the name of the SSID that the user is joining. In this article, we'll look at how you can do this. In this article, I'm going to assuming that we are using a Cisco wireless LAN controller, together with a flavour of Cisco ACS 5.x. I've seen this method used with Cisco ACS 4.x (see references at the bottom of this article) and wouldn't be surprised if you could modify the technique for other RADIUS servers. When Googling about this subject, I don't see any results that show how to do this in ACS 5.x, so thought it was worth a quick note. Background In brief, when a wireless client is attempting to authenticate to an SSID on a Cisco WLC network, if 802.1x is being used to authenticate users, then various RADIUS attributes are sent to the RADIUS server (e.g. ACS) as part of
