Issue in Cisco ACS HA primary and replica

[ivan.martin]

Hello my name is Ivan, i have an issue:

I have two instances of Cisco ACS v5.4 servers primary and replica, working alongside  802.1X PEAP with MAR workin to my wireless network, to authenticate users and computers in an enterprise.

Everything works fine, but from time to time, but soon after the end of the day, the process of authentication of the primary instance, changes to the replica and send these processes acs the replica instance, when that happens, users network can not authenticate, and the wireless network drops.

I set the same policies for both primary and replica instances.

Can you help me please am the problem, perhaps with some advice?

Thank you.

Hi Ivan

Do you have MAR cache distribution setup?

Also what is the error on the secondary when the users fail?

You can sync the MAR cache status for the nodes by defining MAR cache distribution

Go to the "Machine Access Restrictions" tab in the Active Dierctory settings and set the same non-empty value for the

Cache Distribution Group for the two servers in the deployment
