The earliest recollection of this bug is traced back to PAN-OS 10.1.2 - February 19, 2025. This bug is fixed in PAN-OS versions 10.1.2. Fixed an issue where during QoS config generation the Aggregate Ethernet (AE) subnets were incorrectly calculated cumulatively across all AEs instead of calculating just the total subnets of an AE.
