Problems with ATM Address Registration
If you suspect that a Phase 3 problem is due to faulty ATM address registration between an ATM
Workgroup Switch and an attached ATM device, follow the troubleshooting procedures listed below.
Possible problem with ATM address registration
Steps to Take:
1. Enter the SHOW PORT command to make sure that the ATM media port is configured with a UNI interface. If
not, enter the SET PORT command and specify
uni
for the interface parameter.
2. Make sure that the attached device supports the ATM network prefix used by the workgroup switch.
To display the network prefix, enter the SHOW DEVICE command and note the leftmost thirteen bytes of the
workgroup switch’s ATM address.
Check the ATM network prefix supported by the device. If it is different from the prefix set for the workgroup
switch, use the SET DEVICE ATM_ADDRESS command to change the workgroup switch’s ATM address so that
its network prefix is the same as the network prefix used by the ATM device. Be sure to reconfigure the ATM
addresss of other switches that are attached to the workgroup switch.
3. Make sure that the device supports ATM address registration. To check whether the device registered its ATM
address, use the command SHOW ATM_ESI. If you do not find the ATM address, enter the command
SHOW PORT
slot.port VERBOSE
corresponding to the port attached to the device, and check that the status is
OKAY
. If, for
example, the port on the ATM device is configured as
Okay PVC-ONLY
, the device supports only PVC connections.
4. Make sure that the device is not using a protocol for ATM address registration that is incompatible with the ILMI
protocol used by the workgroup switch.
5. Contact your IBM service representative.
