Method used to restore the database package for a non-ASON NG SDH NE


During restoration of the database package on a non-ASON NG SDH NE, some services are interrupted after the database package is downloaded. As a result, alarms such as AU_AIS, TU_AIS, and HP_UNEQ are generated. Is there any method for preventing services from being interrupted during database package restoration?
During database package restoration, if you choose to issue configuration data to boards and the configuration data in the database is different from that on system control boards and cross-connect boards, services will be interrupted.
1. Before restoring the database package, collect the basic configuration information of the NE.
2. Select Restart for the activation type. Do not select the option for issuing configurations to boards.
3. After the restoration is completed, collect the basic configuration information of the NE again, and compare the collected data with the previously collected one.
4. If the data is consistent, perform a warm reset on cross-connect boards and service boards in sequence.
5. If the data is inconsistent, find out the missing services or modified services based on the data collected before restoration to create a configuration script, and configure the services separately. When the data is consistent with that collected before restoration, perform a warm reset on cross-connect boards and service boards in sequence.
6. Check whether services are interrupted.
Suggestion and conclusion:
Restoring the database package is a high-risk operation. Therefore, perform operations following the requirements.

Method used to configure the OSPF protocol for ASON NEs?
In general, it is not allowed to disable the OSPF protocol for an ASON network. In some scenarios, however, disabling the OSPF protocol for ASON NEs can release resources and therefore enable resources to be properly utilized.
