Configuration File Management
This section describes the configuration file management feature, including the definition, benefits, functions, principles, and key indicators of the feature.
Definition
The content of the configuration file on the device changes as the services on the device change or expansion. eSight uses the configuration file management component to back up, compare, and restore configuration files of managed devices.
Benefits
Configuration file management can back up, compare, and restore configuration files, helping users effectively manage device configuration files.
Functions
eSight allows you to import, back up, restore, and compare device configuration files and manage baseline file versions. When faults occur on the network, you can compare the configuration file in use with the configuration file that was saved when the network was running properly. By checking the added, modified, and deleted information, you can quickly locate the fault and resolve it. You can also manage configuration changes. eSight automatically compares the differences between backup and original configuration files to obtain configuration changes and notifies you of the changes by emails.
Device Configuration Management
- Backup task
eSight can periodically (daily, weekly, or monthly) back up configuration files of devices specified in a backup task at a specified time. eSight can back up configuration files when receiving a configuration change alarm. Backup tasks can be executed at regular intervals or immediately after a configuration change alarm is generated. You can receive backup execution results by emails. The attachment in an email provides a list of devices whose configuration files fail to be backed up.
- Configuration file
You can back up and restore the running or startup configuration file of a specified device, specify a configuration file as a baseline version, and change the FTP operation types of selected devices (except non-Huawei devices). You can also view the running and startup configuration files that have been backed up on eSight and export configuration change reports in Excel format.
You can view configuration files that have been downloaded from eSight to a local device.
You can compare, download, import, and delete configuration files. The file comparison function allows you to compare configuration files backed up on the eSight server.
- Configuration change
After a configuration file is backed up, eSight automatically compares the differences between backup and original configuration files to obtain configuration changes. You can check the detailed configuration changes, including file addition, deletion, and modification.
System Parameter Management
- Backup parameter
- You can set the maximum number of configuration files that can be stored on the eSight server for each device. If the number of configuration files of a device on the eSight server exceeds the maximum, eSight automatically deletes the earliest configuration file.
- You can configure whether to send an alarm upon configuration file change.
- You can configure whether to trigger a backup upon device configuration change.
- You can configure whether to save the running configuration during backup.
- You can configure the configuration file backup policy.
- Email notification
You can create a backup task execution result notification and a configuration file change notification. You can select a recipient from existing users or user groups (set in System > System Settings > System Interconnection > Set Notified User > User Group) and set the email subject and notification sending time for the configuration file change notification.
Faulty Device Replacement
Faulty devices can be replaced on the physical topology. You can select the configuration file backup of the original device, deliver it to the new device, and set it as the startup configuration file of the new device.
Principle
You can back up device configuration files in either of the following ways:
- Huawei devices: Configure the MIB node of the device through SNMP, back up the configuration file, and transfer the configuration file to eSight through FTP, SFTP, or TFTP.
- Non-adapted Huawei devices, third-party devices, and S switches failing to be backed up through SNMP: Run the Telnet command to deliver the configuration file backup command to the device to back up the configuration file, and transfer the configuration file to eSight through FTP.
