TAC won't be able to help here I'm afraid. If it's not the exact models sold by PAN, it may work but may not. Support will not check compatibility of transceivers that aren't sold by Palo Alto Networks. The official 3rd party policy is here: https://www.paloaltonetworks.com/services/support/support-policies/third-party-components-support As for the question regarding whether 8.0.6 contains the fix, it does not. You can always look at the release notes for any version to see fixes up-to and including that version. In this instance, the links at the bottom of the Upgrade/Downgrade block that @PaulBrock linked to show the transceiver issue mentioned as PAN-92564. That issue ID is a known issue in 8.1.0 and the latest version of 8.0 (8.0.8). Since it is in the "known issue" section it does not yet have a fix available. When a known issue is fixed, future release notes show what version contains that fix in both the Known Issues section and the Issues Resolved in this Release section. Regarding the reboot question, the caveat listed is "Additionally, after we provide a release with this fix and you begin the upgrade process, you must not reboot the firewall after you download and install the PAN-OS 8.0 base image until after you download and install the maintenance release with this fix." What that means is when you do decide to upgrade from 7.1 to 8.0, you just need to download the 8.0.1 base image but NOT reboot. Instead, download the version that contains the fix (whatever version that ends up being) immediately after downloading 8.0.1. Then reboot to the fixed version. Hopefully this clarifies things a bit! -Greg Wesson
