In FreeBSD, they may be getting dropped due to the "bad pdu received" errors you have reported. And it seems that the switch's SSCOP processing is also not seeing the FreeBSD-generated SSCOP PDUs. So, a couple more debugging steps: 1. Reboot FreeBSD; 2. Patch kernel (this will print out the full "bad pdu" PDU: # gdb -k -wcore /kernel /dev/mem (kgdb) set atm_print_data=1 (kgdb) exit 3. On your switch, enter: stat vcc 1a4 4. Start the FreeBSD ATM software: atm attach ... atm set prefix ... 5. wait a minute or so... 6. On your switch, enter: stat vcc 1a4 7. On your FreeBSD system, enter: atm sh int atm sh stats vcc atm sh stats int idt0 aal5 8. Send all of the command outputs from above and all of the /var/log/messages file from when the system was rebooted until now. Hopefully this will help us narrow down where the problem seems to lie.
