Hi Saravanamuthy,
this is a complex topic with multiple questions so let me sort it out a little:
Maximum RADIUS users
Testing on AP7532 I reached below error for RADIUS user pool % Error: Cannot add user SPbFx_gu_291. Pool has maximum users (256).
Testing on VX9000 I reached below error for RADIUS user pool % Error: Cannot add user xKBV9uSr. Pool has maximum users (20000).
Only one person should use credentials
Command you are looking for is "simultaneous-users x" in Captive Portal policy The number of MAC addresses that are allowed to use that username at the same time.
How to configure in GUI on AP7532
- if your AP has Enterprise UI, then do it here (Configuration - Services - Captive Portal)
In case the AP does not have Enterprise UI, read article
how to change SwiftUI to Enterprise
Here you can also find reason for
404 server error when accessing WebGUI in case you use LEAN image.
