Operational impact of having monitoring nodes unreachable?

Just a quick question, is there an operational impact to radius and tacacs auth if for some reason both our primary and secondary MnT nodes go offline? I'm currently running off our secondary MnT and want to know the impact to our operations if we lose both.

There is no operational impact. But you will loose the logs for the sessions when MnTs are unavailable. 

Also, in case of URL redirect flow like Posture/Guest/BYOD, if PSN becomes unreachable  at the same time as MnT, there are possibilities of stale sessions since the session information is not available for the next PSN to issue a CoA.

 

Thanks,
