I have an ASA5512-X in a lab. It was running 9.12.4.10 up until yesterday. I upgraded it to 9.12.4.13 and rebooted it. I then lost contact with it.
Its outside interface was GigE0/6 and the inside GigE0/0. When it rebooted the switch the outside interface was connected to went down and then came up at 10Mbps Full-Duplex (previously was 1Gbps). I reset the switch interface a few times but the input packet count never incremented and it always came up at 10Mbps Full-Duplex.
I eventually got console access and was expecting ROMMON, however it was up and working but it only had interfaces GigE0/0 thru Gig0/3 and Management0/0. I had connectivity to devices via the Ma0/0 and GigE0/0 interfaces. The startup configuration showed the GigE0/4 & GigE0/5 interfaces but the device itself only showed GigE0/0 - GigE0/3. I reverted the ASA image to the previous one and rebooted but still had the same behaviour so I reconfigured it so all configuration relating to GigE0/5 moved to GigE0/3 and moved the cable. On the switch I saw the interface go down when the cable was moved and then come back up at 1Gbps so I thought we were OK. However the ASA showed the GigE0/3 interface as down. I had a spare ASA5508-X so I got this swapped in and have recovered the service.
I still have console access and the Ma0/0 and GigE0/0 interface are still working so I did some investigation. If I reboot to ROMMON it can only see the Ma0/0 and GigE0/0 interfaces. Nothing looks unusual on the console during boot (apart from it not seeing the other interfaces) so I am perplexed.
This is obviously a hardware fault but I've never seen this before? All the Intel ASA5500-X's I've worked on have been solid. The interfaces are all on the motherboard so its not like a module has come loose?
I know the ASA5512-X is coming up to EoL but its still a worthy device. What is the warranty status on these devices? Do they come with limited lifetime warranty like Catalyst 3k switches?
