I'm posting this to find out if anyone else has experienced this problem and to notify others of a possible bug that can shut your Firepower connection down.
This is the third time now that the Outside port of our Firepower Suite has disconnected from our service provider. Each time this has happened I've been running packet captures using the vFMC gui.
I think the action that I'm doing when the port disconnects is that I clear or delete the capture without pausing or stopping the capture first.
SETUP
Two FP2110 Firepower devices configured in an HA pair.
One virtual FMC appliance hosted on a vCenter 6.7 cluster with UCS hardware.
Running a capture shouldn't cause the outer port to disconnect. The fix has been to disable and re-enable the port.
Several people have told me I should just use the command line to run captures, but that's another story.
I've opened a ticket with Cisco, but in the mean time I wanted to find out how wide spread this might be. This has happened to us using 6.2.0.3 code and now 6.3.0.3. We've been told to upgrade to 6.4.0.4 to see if that will fix it.
Please share any experience you may have seen and I'll let you know when it gets fixed.
