CirrusR-Series after upgrading to 1.8 - RADIUS Auth stopped working
Radius user authentication was working just fine while running v1.40. After upgrading to 1.80 any attempt is "Failed authentication."
Running tcpdump does not show any traffic going to the RADIUS server and the RADIUS server has not entry of the failures in it's log.
I have deleted and recreated the radius server group - that did not help. I have deleted and recreated users - that did not help.
Any guidance for what to try next is appreciated.

Hi Dave,

After upgrading to F5OS 1.8.0, the RADIUS authentication process for the F5OS management interface (webUI) requires specific F5 Vendor-Specific Attributes (VSAs) to be present in the RADIUS server's response. If these attributes are missing, authentication will fail, and you may not see any RADIUS traffic in tcpdump if the system is not even attempting to send the request due to misconfiguration.
