If you see only the sent or received counter incrementing, it may means that cells are being stuck on the
backplane causing ILMI to be stuck. Try issuing a shut/no shut command on the interface. If that does not
help, contact Cisco Technical Support for further troubleshooting. If both counters are incrementing, then the
ILMI PVC is transmitting cells properly.
Known Caveats
There are also some known bugs which can explain why ILMI is not coming up properly. These are Cisco
Bug IDs CSCdt47492, CSCdm26756 and CSCdr28332.
To follow the bug ID link below and see detailed bug information, you must be a user and you must be .
The rest of this document assumes that the ILMI PVC is UP and carrying cells and that the ILMI status is
correct on all the devices. Then, the possible causes for address registration failures via ILMI are:
The switch already knows the NSAP address•
Configuration problem•
If the Switch Knows the NSAP Address
These are scenarios in which the switch already knows the NSAP address.
When the NSAP Address Is Configured Statically on the Switch
On the router Bernard, you can see this message:

When looking on the switch for the NSAP address 47.00918100000000603E5A4501.00D0069A7C40.01, you
can see this information:
