Troubleshooting
This chapter explains how to troubleshoot operational difficulties with the
X330WAN, and includes the following sections:
•
Monitoring Traffic - An explanation of the output from the CLI command used
for monitoring the E1/T1 port’s status.
• Handling E1/T1 Alarms - A list of alarms including alarm indicators,
explanations, and methods for handling alarm situations.
• Using Loopbacks - Instructions for using loopback tests to determine the cause
of an alarm condition.
Troubleshooting the X330WAN should be performed according to layers. When a
problem appears, begin isolating it by troubleshooting Layer 1 - the controller’s
alarms and errors, then proceed to Layer 2, and finally Layer 3.
Monitoring Traffic
You can monitor the state of the X330W-2DS1’s E1/T1 ports by entering the
show controllers command. 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.
Following is an output example for the show controllers command for an E1
port:
E1 1 is up.
No alarms detected.
Framing is CRC4, Line Code is HDB3, Clock Source is
