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:

1w1d: %LANE−3−NOREGILMI: ATM2/0/0.1 LEC cannot register 47.00918100000000603E5A4501.00D0069A7C40.01 with ILMI

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