Problem Description

The Cisco Firepower 4100 and 9300 Series Security Platforms (FPR4100 and FPR9300) that run the affected Firepower eXtensible Operating System (FXOS) software versions reboot after approximately 210 days of uptime.

If the output from the show version command indicates that your platform currently runs an affected FXOS software version, then enter the show version | i uptime command in order to determine the length of time that the platform has been up.

FPR4120-A# connect fxos
FPR4120-A(fxos)# show version | i uptime
