Loopback Test Options

The loopback tests do not monitor the integrity of the data but rather the integrity of the path. The type of loopback indicates the direction of test data transmission. The choices are:

far end means the service module transmits data to the CPE and receives the data back

remote means the service module receives data from the CPE and loops back to the CPE

metallic means the service module receives data from the network and loops it back to the network

Online Diagnostics test

The Online Diagnostics are used to test components on the PXM1 and SRM modules of the MGX 8230 while the shelf is running. Connections, states, and tasks are not affected by the tests.

The diagnostic test is invoked from the active PXM1. If a standby PXM1 exists and is in standby state, it will also be tested. When the test is run, each component is checked and the results are presented on the screen. Results are also saved to a log file.

Automatic Switchover

The Online Diagnostic command (oldiags) includes an option to automatically switch operations from the active PXM1 to the standby PXM1 if a major problem is detected. This behavior is possible only when a standby PXM1 is installed and no errors are detected on that standby PXM1 during the test.

Alarms

If a failure is detected and an automatic switchover is not performed, a major alarm is set. This alarm is displayed in the card Major Alarm Bit Map field when the command dspcd is entered. The alarm message indicates the failed PXM1 by slot.
