Solved: Firepower Appliance / Registration to FMC Failure Scenarios

cmlozano8 · ‎11-21-2017

Hey Guys,

We have an FP2110 with FTD which is currently deployed and in production. Currently the appliance is on site and the FMC is hosted at a data center connected via a site to site vpn. My question is what if you made a mistake on configuration or had to switch carriers on the appliance. If the FMC loses connectivity to the Appliance how can you restore it? From what I can tell there is no CLI that configuration can be done though.

Any Thoughts?

Hi,

It should recover else maybe setup a remote console to reboot the device via oob if it's far away.

It is documented anywhere that it will indeed recover if it loses connectivity to the FMC? Like a config rollback?

Hi,

As long as FMC or FTD is not changing IP address you should be ok.
Because you can reboot the FMC anytime without any connectivity issues.

Only if you didn't mess things up - like changing a firewall rule or NAT or VPN that you were using to reach the console in a way that breaks it, so rebooting won't help.
