You need to regularly maintain the system to ensure that the system keeps running normally.

7.1 Maintenance Items

This section introduces some common maintenance items.

7.2 Daily Maintenance

The purpose of daily maintenance is to monitor the operation status of the devices and network

in real time, and improve the efficiencyof handling emergency cases.

7.3 Weekly MaintenanceThe purpose of weekly maintenance is to find defects such as malfunction or performance

deterioration during the operation of the devices. You can then take proper actions to remove

the problems and avoid accidents. Youcan also back up data to avoid data loss.

7.4 Monthly Maintenance

The purpose of monthly maintenance is to keep the devices in a good condition. This ensures

that the T2000 can run securely, stably, and reliably.

7.4.1 Checking Consistency of Configuration Data Between an NE and the T2000

A consistency check is done to compare the configuration data in the NEs with the data in the

T2000. After the check, a report of the result is created. If the result shows the configuration

data is inconsistent, you need to upload the configuration data from the NE to the T2000 ordownload the data from the T2000 to the NE for data synchronization.

To ensure the NE security, you need to periodically change the passwords of the NM and NE

users and keep them in a safe place.

7.4.3 Deleting User Rights

You should delete user rights periodically to ensure the security of the T2000.

7.4.4 Viewing the T2000 Operation Logs

All NM users' operations on the T2000 and NEs are recorded in the operation logs. The

T2000 provides the ability to view the logs and different ways to filter the operation logs.

7.4.1 Checking Consistency of Configuration Data Between an NEand the T2000

A consistency check is done to compare the configuration data in the NEs with the data in the

T2000. After the check, a report of the result is created. If the result shows the configuration

data is inconsistent, you need to upload the configuration data from the NE to the T2000 ordownload the data from the T2000 to the NE for data synchronization.

Prerequisite

You must be an NM user with "NE and network operator" authority or higher.

Context

l Configuration data consistency check between the T2000 and NEs does not change the

configuration data in the NEs and in the T2000.

operators.

l Assign user rights by user group. Add users with similar rights to the same group. To maintain

system performance, do not assign rights to users one by one.

----End

7.4.4 Viewing the T2000 Operation Logs

All NM users' operations on the T2000 and NEs are recorded in the operation logs. The

T2000 provides the ability to view the logs and different ways to filter the operation logs.

Prerequisite
