Cisco Secure ACS v5.8 deployment

[Jay Russell Santos]

Hi Experts,

We are currently deploying Cisco ACS v5.8 as a Proxy Radius Server. Client side is using Cisco ACS v4.2 as the Radius Server. Will there be any incompatibility issues? I believe there's no issue for this. just making sure. 

I think the question is not between v5.8 as a radius server and v4.2 as the radius server. For me, proxy radius server will only point to radius server. The thing that we need to check is between WLC  5520 software version 8 compatibility to ACS 4.2.

Thanks.

Hi,

Radius servers wouln't make any difference in the process. However,

I've looked at Cisco Documents and found 2 different answers.

Cisco 8.0.100.0 Software release notes says, ACS 4.2 is compatible; where as Cisco Wireless software compatibility matrix says, ACS should be atleast on code 5.2 or higher.

From the below AirOS 8.0.100.0 release notes ; Table 6 :Test Bed Configuration for Interoperability

From the below Cisco Wireless software compatibility matrix: Table 8 Software Compatibility Matrix

Hi Gagan,

I also read about that.

Thanks.

Hi, I would suggest to upgrade ACS 4.2 to 5.x that would be the best option.

To make it compatible!!!!!

As you know ACS 4.x is EOS and EOL.
