As shown above, the NSAP address has been statically configured on the switch and in this case even points to a different interface from the one where it should be located.
When the NSAP Address Is Registered via ILMI by Another Device
To simulate this scenario, Tintin and Bernard are configured with the same MAC address.
Bernard
interface ATM2/0/0
mac−address 0000.0000.0001 pvc 0/16 ilmi
!
pvc 0/5 qsaal
Tintin
interface ATM1/0
mac−address 0000.0000.0001 no ip address
atm pvc 1 0 5 qsaal atm pvc 2 0 16 ilmi
Because they are both connected to the same switch, the NSAP address associated to the LECs configured on the sub−interfaces atm 2/0/0.1 and atm 1/0.1 is the same: 47.00918100000000603E5A4501.000000000001.01.
Tintin interface atm 1/0.1 has been brought up before atm 2/0/0.1 on Bernard. Therefore, Tintin is the first one to register the NSAP address 47.00918100000000603E5A4501.000000000001.01 via ILMI. As soon as the interface atm 2/0/0.1 is brought up on Bernard, this message is displayed:
1w1d: %LANE−3−NOREGILMI: ATM2/0/0.1 LEC cannot register 47.00918100000000603E5A4501.000000000001.01 with ILMI
