Hi ,

There is no concept of Active/Active in ACS 5.x . How ever both acs can perform authentication. You can mention half device to point to ACS1(Primary)  and other half to ACS2(Secondary)  . However the master DB will be in Primary ACS

Thanks

We need to configure some of the AAA clients with first ACS as primary and for other devices configure the second ACS  as primary

Switch 1:

Tacacs-server host

Tacacs-server host

Switch 2:

Tacacs-server host

Tacacs-server host

This is how we share the loads between 2 ACS servers .

Please let me know if you require any more clarifications

Hello aitkaddour,

I think that you can do the load balancing between both the ACS as told by Angus:-

Switch 1:

Tacacs-server host

Tacacs-server host

Switch 2:

Tacacs-server host

Tacacs-server host

Now if your both the ACS are active then your  switches will perform their functions and will redirect the clients on their respective servers.
