Redundancy between two NAC instances

Redundancy between two NAC instances

Hello, everybody,

how could I set redundancy between two NAC instances?

I have set up MAC and 802.1x auth on my switches, but it works until NAC is alive, so it's kind of time bomb: when NAC is offline nothing works. I want to setup redundancy - is it possible?

Many thanks in advance

I've applied the configuration on Friday, January, 12th. On Tuesday, January, 16th there is no anyting related to Secondary NAC on the switch. So, it is no so easy.... Something doesn't work.

Hi,

Agreed ,
once you enforced from NAC switch will be conigured for both primary and secondary server.

Thanks,

if you use up-to-art firmware and you specified cli credentials then the only thing you need to do is: Add second engine to the group. Add/modify the switch in the XMC (netsight) to referr to both engines, define vr, realm, accountig enable... Enforce the configuration. The engine will configure your switch throug the CLI properly. Just wait 2-5minutes. You do not need to add those two lines manually, but you can  Regards. Z.

Thanks, Zdenek! I've got it(

80% of switches are x430 family which couldn't run EXOS's 22 code(

Will my configuration with manual addition of secondary NAC on switches work?
