Diagnosing Problems with ATM Ports Attached to ATM Devices
After you attach ATM devices to ATM media ports, the status of the ports may still not
change to OKAY (ready for ATM traffic). To diagnose this type of Phase 3 problem,
follow these steps:
1. Use the SHOW PORT VERBOSE command (described in the
ONcore Switching
Hub/CELLplex 4000 ATM Command Reference Guide
) to display the status of each
port.
2. If the status of an SSI or UNI port is NOT IN SERVICE:
Refer to “Diagnosing Problems with ATM Ports” on page 7-15.
Make sure that the attached ATM device is operating properly (for example, the
daemon is running).
Check the ATM address registration as described in “Checking ATM Address
Registration” on page 7-22.
Perform the the Wrap test as described in the WRAP EXTERNAL command in
the
ONcore Switching Hub/CELLplex 4000 ATM Command Reference Guide
If
the test results show that the port status is KO, replace the module.
3. If the status of a port is NO ACTIVITY and if a Turboways* 100Mbps workstation is
attached to the port, make sure that the device is correctly installed:
Refer to “Diagnosing Problems with ATM Ports” on page 7-15.
Make sure that the adapter is securely plugged into the port.
Make sure that the cable is securely plugged into the adapter.
Make sure that the device driver is correctly installed by de-installing it and
re-installing a new one.
4. If the status of a UNI port is Okay PVC-Only, make sure that the ATM address of the
attached device supports the ATM address registration of the UNI port.
Important: When a port's status is Okay PVC-Only, only PVC connections are
supported.
If the UNI port is attached to another hub or switch, you may prefer to define the
port as an SSI or NNI port, to be able to establish SVCs.
