Please send along the output of: atm sh conf atm sh int atm sh net atm sh vcc atm sh ipvcc The code that implements ATMARP is in src/sys/netatm/uni/uniarp*. The Inverse ATMARP processing for dynamic IP PVCs gets started in uniarp_vcm.c:uniarp_pvcopen() via the call to uniarp_inarp_req(). If you want to trace the ATMARP packets, you need to: o compile your kernel with 'options DIAGNOSTIC' o gdb -k -wcore /kernel /dev/mem set uniarp_print = 1 set atm_print_data = 1 This will spew ATMARP packet dumps via kernel printf()'s - not pretty, but it works. -- Mike Spengler Network Computing Services, Inc.
