HTB PPPoE Configuration

Hello my Kind Folks,

I have a Mikrotik CloudCore Router 1009 v6.39.29stable). I have 400 clients connnected to the service via PPPoE on a HTB protocol (Mangle + Queue Trees). However, I seem to have a problem managing the individual bandwidths.
Please could someone kindly share with me a similar config setup so that I can compare? The max limit is 5Mbps, burst limit of 10Mbps and a burst period of 5s.
How can I make sure that clients only get a maximum of 10Mbps? When I check the graphc in the morning some clients seem to have been using more than 18Mbps.Someone, anyone… please assist me.


Regards,
Mike Musembi.
