Chapter 5
Troubleshooting
This chapter provides an explanation of how to troubleshoot operational difficulties
with the X330WAN.
Troubleshooting the X330WAN should be performed according to layers. When a
problem appears you should start isolating it by troubleshooting Layer 1 - the
controller's alarms and errors first, then Layer 2, and finally Layer 3.

Monitoring Traffic

You can monitor the state of the X330WAN's E1/T1 ports using the
show controllers command. The command can be entered via the CLI. The
resulting output provides information about the state of the E1/T1 controller and
reports alarms. In addition, the output provides statistics on the state of the
controller over the last 24 hour period. To receive output for a specific port, enter
the port number after the show controllers command.
For information on the fields in the output from the show controllers
command, see Chapter 7, "X330WAN CLI Commands."

Handling E1/T1 Alarms

Alarms are reported by the LEDs on the X330WAN and via the CLI. When an alarm
condition is detected by an X330WAN, the module sends a signal to all E1/T1
devices to which it is attached. Alarms can therefore be categorized as one of the
following:
• Local Alarm Indication - Generated by the X330WAN as a result of a line status
problem sensed by the X330WAN.
• Remote Alarm Request - Received by the X330WAN from the remote module.
The following table provides a list of alarms, the type of alarm, and the alarm
condition on the module from which the alarm originates.
