The WXCP Protection Configured for the LOG Board Is Invalid

The WXCP protection configured for the LOG board is invalid due to the configured attributes of the board.

Product

OptiX Metro 3000

OptiX Metro 6040

Fault Category

Protection

Symptom

The LOG board is configured with the correct WXCP protection.

During a protection switching test, services are interrupted because there is no protection channel to which the services can be switched; however, no alarms are reported to the T2000.

Check whether the protection configuration is correct.

If you delete the protection group and then configure a new one, the fault persists.

Cause Analysis

The WXCP protection configured for the LOG board is invalid due to the configured attributes of the board.

Procedure

1. Check the LOG board of the protection group.
   1. In the NE Explorer, select the LOG board to be checked.
   2. Select Configuration > WDM Interface from the Function Tree.
   3. Click the Advanced Attributes tab.
   4. Check whether the Max Packet Length is 9800.
2. In this case, set the value of this parameter to 1511.
3. Because the value of the parameter cannot be changed, set the LOG board.
4. After the LOG board is reset, the value of the parameter is displayed as 9800.
5. Test whether the fault is cleared. If the fault is cleared, the WXCP protection becomes valid.
