Introduction
This document explains how to troubleshoot Interim Local Management Interface (ILMI) address registration problems on Cisco devices when using LAN emulation (LANE).
The ILMI protocol uses Simple Network Management Protocol (SNMP) format packets across the User−Network Interface (UNI) to access an ILMI Management Information Base (MIB) associated with the link within each node. The ILMI protocol facilitates network−wide auto configuration by allowing adjacent nodes to determine each other's characteristics. Examples of these characteristics are the size of each other's connection space, the type of signaling used (UNI or NNI), type of link (public or private) and hooks for network management autodiscovery.
ILMI is also used for address registration.

Associated Error Message

Address resolution problems are usually associated with the following error message:
%LANE−3−NOREGILMI: [chars] [chars] cannot register [ATM address] with ILMI
For example:
%LANE−3−NOREGILMI: ATM2/0/0.1 LEC cannot register
47.00918100000000603E5A4501.00D0069A7C40.01 with ILMI
This error message can be reported by one of the following:
LAN Emulation Configuration Server (LECS)•
LAN Emulation Server (LES) or broadcast and unknown server (BUS)•
LAN Emulation Client (LEC)•
Although this document looks at the address registration problems encountered by a LEC, the explanations are also valid for registration problems with the LECS and LES/BUS.

Configure

Network Diagram

This setup illustrates the problem:
This setup uses:
Bernard is a Cisco 7500 router running Cisco IOS® software release 12.1(4).•
Casimir is a LightStream 1010 running Cisco IOS software release 12.0(13)W5(19b)•
Tintin is a Cisco 7000 router running Cisco IOS software release 11.2(22)P.•
This setup uses LANE, and the LECS and LES/BUS are located on the LightStream 1010.
Note: The configuration used here does not give the best LANE performances; it is simply being used for illustration. For design recommendations regarding LANE services, refer to the LANE Design Recommendations.

Configurations

Both Bernard and Tintin are configured with a LEC:
Bernard
interface ATM2/0/0
pvc 0/16 ilmi ! pvc 0/5 qsaal ! interface ATM2/0/0.1 multipoint description *** ILMI addr. registr. test *** lane client ethernet ilmi−test
Tintin
interface ATM1/0
atm pvc 1 0 5 qsaal atm pvc 2 0 16 ilmi ! interface ATM1/0.1 multipoint description *** ILMI addr. registr. test *** lane client ethernet ilmi−test

Checking ILMI

ILMI Status

The first thing to check in the case of address registration problems through ILMI is whether the ILMI permanent virtual circuit (PVC) is up using these show commands:
On a router, issue the show atm vc command.•
On a LightStream 1010, issue the show atm vc interface atm x/y/z command.•
bernard# show atm vc
VCD / Peak Avg/Min Burst
Interface Name VPI VCI Type Encaps SC Kbps Kbps Cells Sts
2/0/0 9 0 5 PVC SAAL UBR 149760 UP
2/0/0 1 0 16 PVC ILMI UBR 149760 UP
!−−− Output suppressed.
Casimir# show atm vc interface atm 0/0/0
Interface VPI VCI Type X−Interface X−VPI X−VCI Encap Status
ATM0/0/0 0 5 PVC ATM2/0/0 0 47 QSAAL UP
ATM0/0/0 0 16 PVC ATM2/0/0 0 35 ILMI UP
!−−− Output suppressed.
If the ILMI PVC is up, then you must check which ILMI state the router and the atm switch are in. Do this by issuing the show atm ilmi−status command.
