The issue you're facing with the Nexus 9364C running NX-OS 10.4(4), where users are unexpectedly assigned a lower privilege role despite identical TACACS configurations, highlights how software updates can alter underlying behavior—even when configurations remain the same. In this case, it’s likely that role-mapping logic or enforcement policies have changed subtly in NX-OS 10.4(4), especially for newer hardware models like the 9364C. You may need to define explicit role maps using tacacs+ role-map and confirm that the TACACS server is returning the correct roles or attributes. This is a known occurrence with certain NX-OS versions where defaults shift slightly between versions or hardware lines.
Relating this to Snapseed QR codes Aesthetic it’s similar to how a filter or preset works perfectly on one photo but gives unexpected results on another—even though the QR code is the same. Different devices, image resolutions, or Snapseed app versions can interpret the same QR filter preset differently, just like how the same TACACS config behaves differently depending on the NX-OS version or hardware. In both cases, the “input” is the same, but the “environment” causes the result to vary. Knowing this, it's always good to test across all intended platforms before assuming uniform behavior.
