Radius mac-caching-time not working

RouterOS General
1

Hi!

I’ve implemented radius authentication in a wireless profile. All works fine, except the mac-caching-time, wich is defined to 00:00:30. This configuration is not working, because the Mikrotik asks to radius once when a new MAC tries to associate, and seems to keep the result in cache forever. If I disable and enable the interface, it asks radius again. I’m using RB433AH with v5.5.

I have found this topic without solution, but is very old… http://forum.mikrotik.com/t/mikrotik-3-x-and-troubles-with-mac-caching-enabled/22446/1

Any hint?

Thanks in advance.

Same behavior since 4.11 to 5.15.

Does it simply won’t work? Neither an answer from the team?

Have you sent an email to support@mikrotik.com with your issue?

If not, create an supout file and send an email to them explaining this.

Best regards,

Hello,

from what I have just tested with a 5.20 AP, the time unit of the radius-mac-caching parameter should be in minute.

If I set a station to be rejected in Radius and the radius-mac-caching to :

interface wireless security-profiles set 1 radius-mac-caching=1

RouterOS shows :

radius-mac-caching=1s

but the log with radius and wireless details show that radius requests are done every 2min.

If I set radius-mac-caching=2, requests are done every 4min.

I guess the base unit of radius-mac-caching is more “minute” than “time interval”.
