Integrating rujie with extreme control

[Ahmed_101]

Hi all, 
I have an issue where i have a rujie switches and cisco switches for a customer.
So i configured mac authentication in cisco switches and it works fine but when i configured it on rujie switches i encountered issue where the rujie switch is sending radius packets to extreme control engine but the engine doesnt seems to send any response back. 
Here is some information from the rujie switch.

Any help will be appreciated.

Check the message authenticator attribute on the switch settings in Control. By default this is set to required and if the switch does not include it, the request will be silently dropped.

The Message-Authenticator is now required by RADIUS clients due to last year's BlastRADIUS vulnerability. See https://extreme-networks.my.site.com/ExtrArticleDetail?an=000121853 for some additional detail.
