Inline Posture between Cisco ISE and Wireless LAN Controller

Unanswered Question

I was looking into Cisco ISE solution for deploying NAC.

I have a question about the network topology.

In  the user guide documents of cisco ISE, it is written that for Wireless  LAN Controllers (WLC) and VPN devices, an additional server, Inline Posture, is needed.

However, in the following integration document, there is not an inline posture between WLC and Cisco ISE server.

I  want to know if Inline Posture is a requirement, if not a  requirement, what are the benefits of having it between Cisco ISE Server  and WLC.

Thanks & Regards

When doing posture assesment, ISE Needs to send information ack to the network device to change parameters, for example vlan change. In switches this is done with CoA, an extention to the radius protocol.

WLC doesnt support CoA as of v7.1.

Later versions of WLC do support COA. There are versions currently shipping that do support COA
