Diagnosing Problems with ATM Ports
If all ATM modules are operational (connected, hardware okay, and normal displayed
with SHOW MODULE VERBOSE), the cause of the problem may be due to an
inoperational ATM port. To see if the ATM ports on a given module are functioning
correctly, use the SHOW MODULE and SHOW PORT commands to display port status.
Any of the following types of port status may appear:
Unknown
Error
No Activity
Not In Service
Okay
Okay PVC-Only.
The problem associated with each port status (except for Okay) and the action to take
to solve it are described below.
Status: Unknown
Explanation: Port status is not available because port is not reachable.
Steps to Take:
1. Use the SHOW MODULE command to check if the ATM media module is
connected to the 6416SW module.
2. If the ATM media module is not connected, use the SET MODULE command to set
the network parameter to connected.
If the module is connected, reset it using the RESET MODULE command.
3. The FPGA of the module is not compatible with the FPGA or microcode of the
6416SW. Check the prerequisites in the release Note..
4. If the problem persists, replace the ATM media module.
