What are the CLI commands or where in the FMC can you see if the firewalls lost power "Up Time" or lost network connections to the outside?
We had a scheduled building generator check and some odd things happened that pointed to losing our network connection. I tried reviewing the firewalls and FMC, but I can't seem to located the commands or menu to find the Up Time of the device.
None of the expected commands nor a question mark searching for commands could identify what to use. I've tried the show commands using environmental, system, chassis, server and others, but the output didn't provide any indication of "Up Time".
Firepower 2110's and FMC running 6.4.0.7

if you log into the FTD device and issue the show version command, you will see the up time there.

That post was taken straight out of an FTD4110 so, yes, it does provide that output

When planning your deployment always check the datasheets to make sure the device you are considering supports your requirements.
