Is it necessary disable pppoe-client in client Device?

RouterOS General

Hi everybody,
We offer Internet service using a wireless AP.
I have a central Mikrotik with a PPPoE-server. My clients have its own Mikrotik CPE with a pppoe-client.
If a client does not pay the Internet service, we disable his pppoe account in my central server.
In one PPPoE-server I can have 150-200 clients, this device is a RB1000 and my problem is the CPU usage vary between 33%-90% each 5 seconds.
Each second my pppoe-server have a pppoe request and there is lots of request from a disabled clients.
Is it necessary that I have to disable the pppoe-client in the clients’ CPE when a client does not pay me?

Thanks,
Santiago

If you are not allowing pppoe client to connect, it will try all the time taking router’s resources. Better solution would be to allow client to connect but drop everything from/to this interface in firewall.
