We've been having this strange issue wherein the firewall would disconnect or stop communicating to TACACS server. We recently migrated to Cisco ISE from Cisco ACS and for some strange reason there will be times (a lot of times) that the ASA will stop talking to the AAA server and will switch to local authentication. I don't know if there's something with the ISE that's breaking these firewalls because they're running different code and this just started to happen when we moved to ISE. With ASAs, it would take 10 minutes or so to recover from that so it's going to take a while to gain access again to the CLI unless I use a local credentials.
Anyone here experienced the same thing?
I cannot login to ASA because the we recently changed our ways and our local password is in password vault of our manager. So I will need to vontact him every time it happens so I can capture logs.
We have an automation server that logs on a regular basis and I think eventually it will break and by the time I log in it's no longer authenticating.
