[c-nsp] c7206 ios for dsl aggregation

Wed Jun 21 02:26:57 EDT 2006

Thank you for your answers, here is my conf if someone need it.
The exact problem is :
    the c7206 is a ISG connected to DSLAM with the atm interface
    no l2tp in the conf but atm aggregation
    I'm using dbs to config user's pvc by radius

the pbm : some times more and more users can not connect anymore, and 
their traffic doesn't come to my 7206, atm debugging doesn't show any 
cells from those ones... If I reboot the 7206 everything comes back to 
normal, if I do a shutdown/no shutdown of the atm interface, no change, 
I really need to reboot the cisco...
here is the conf :
