The earliest recollection of this bug is traced back to PAN-OS 11.1.10 - May 15, 2026. This bug is fixed in PAN-OS versions 11.2.10-h8., 11.2.7-h15., 11.1.10-h26, 11.1.13-h6.. Fixed an issue on PA-415, PA-415-5G, PA-445, PA-455, and PA-455-5G platforms where certain PAN-OS versions caused intermittent connectivity failures on the Eth1/1 data port and loss of power on PoE ports. On PA-415, PA-415-5G, PA-445, PA-455, and PA-455-5G platforms, certain PAN-OS versions may cause intermittent connectivity issues on Eth1/1 SFP/RJ45 data port. Additionally, devices onboarded or managed via Eth1/1 lose call-home connectivity post-upgrade. The dedicated management port SFP or RJ45 are not affected. On the following platforms, PoE ports will not supply power. Ethernet traffic on PoE ports continues to function for devices that do not require inline power.
