[rbak-nsp] high aaad load because of automatically redial modem

[Navin Nepali]

I had same issue. My Se800 CPU was always 99%. I had done PADI/PADR throttling since then my cpu dropped to 70%. 
 
you can use this command to do throttling:
 

pppoe circuit padi/padr per-mac count padi-num allow-time allow-interval drop-time drop-interval
 
Thanks

Hi Ahmed,

Why don’t you create a new context for these subscribers that has no route out to anywhere.
With radius you guide that “non-paying” customer towards this context and provide him any IP address from the pool.
He’s stuck there, if you like you can add a redirct for HTTP towards a server which displays the message that he should pay for his use.

Kind regards,


Frans.

hi guys, i have issue about redback se-800, 
when each first date of the month we have enourmous fail authentication issue and its because we have blocked bad debt customer (the customer didn't pay for their last month usage so we blocked them with a flag in radius), but since the customer using pppoe connection and their modem is automatically redial, they keep authenticating and bras keep rejecting. This situation make the bras aaad process so high (about 60%) and sometimes make it halt and collapsed the bras so it cant process anymore request and trafic. do you have the solution about this problem ?
