RADIUS access-accept/accept-reject packets are not logged in Splynx.
Instead of this, you can find RADIUS log files where all logins, MAC addresses, IP addresses are mentioned.
By default only short log is enabled. /var/www/splynx/logs/radius/short.log.
However, if you need more information, you can enable debug log. /var/www/splynx/logs/radius/debug.log (Not recommended to enable it for a long time).
Logs can be configured under Config / Networking / Radius extended
If you want to change/configure or add/remove Radius Attributes that are transmitted in RADIUS accept packets - this can be done under Config / Networking / Radius
Use any of these fields: Customer attributes field, Plan attributes field, Rate-Limit attributes
Please Note! It takes some time to apply RADIUS configuration. Up to 5 minutes.
