rasd is a RADIUS client simulator for testing a AAA or RADIUS server. It can create thousands of sessions which would then simulate actual active users by generating RADIUS requests.
You can have control over simulation by creating a RAS type. Currently, RAS type for Mikrotik devices is useable.
Configuration: You would create one or more simulation profiles. available parameters are explained in the sample rasd.conf
Run: python ./rasd.py -c rasd.conf
For more information take a look at the rasd.conf .
