The system software provides drivers and adaptation functions for hardware, and offers service features. The BIOS software and system software are prerequisites for device startup and operation, providing support, management, and services for the device.

NOTE:

The BIOS software is included in the system software package (.cc file) of the device. The BIOS software is automatically upgraded in system software upgrade.

Procedure

Choose System Management > System Maintenance > AC Upgrade. The AC Upgrade tab page is displayed.

You must restart the device to make the system software take effect.

17.1.4 Patch Management

Context

A patch is a kind of software compatible with the system software. It is used to remove the urgent bugs of the system software. Patches can also fix errors or improve adaptation of the system software. For example, patches can fix defects of the system and optimize some functions to meet service requirements.

The patches are released in patch files. A patch file may contain one or more patches with different functions. When patch files are loaded from the storage device to the patch area in the memory, a unique sequence number is assigned to each patch file to identify, manage, and operate the patches.

Procedure

Choose System Management > System Maintenance > Patch Management. The Patch Management tab page is displayed.
Figure 17-4 Patch Management
Click Browse and select the patch to upload.
Click Upload to upload the patch to the device.

17.2.2 Service Management

Context

In the TCP/IP protocol suite, the Telnet protocol applies to the application layer. The Telnet protocol provides remote login and virtual terminal functions through networks. Telnet is implemented based on the client/server model. Telnet clients send requests to the Telnet server that provides the Telnet service.

The File Transfer Protocol (FTP) applies to scenarios that do not require high file transfer security. FTP is widely used for version upgrades.

Secure Shell Telnet (STelnet) ensures secure Telnet services. STelnet secures client access on a traditional insecure network by authenticating the client and encrypting data bidirectionally.

The Secure File Transfer Protocol (SFTP) secures file transfer on a traditional insecure network by authenticating the client and encrypting data bidirectionally.

If you do not perform any operation before the web service times out, the system forcibly logs you out and prompts you to log in to the web platform again when you perform an operation. The default web service timeout period, 10 minutes, is recommended.

Procedure

Perform service management.
1. Choose System Management > System Configuration > Service Management.
  Figure 17-8 Service Management
2. Set FTP to Enabled or Disabled to enable or disable FTP.
3. Set Telnet to Enabled or Disabled to enable or disable Telnet.
4. Set STelnet to Enabled or Disabled to enable or disable STelnet.
5. Set SFTP to Enabled or Disabled to enable or disable SFTP.
6. Set Web service timeout.
7. Click Apply.

Create a remotely trusted host.

Choose System Management > System Configuration > Service Management.
In the Remote Trust Host IP area, click Create. In the Create Remote Trust Host IPdialog box that is displayed, set parameters. Table 17-8 describes parameters for creating a remotely trusted host.
Click OK.

Table 17-8 Parameter description

Parameter	Description
IP Address	IP address of the remotely trusted host.
Description	Description of the remotely trusted host.
Available service	Service type that a remotely trusted host can access. A remote trust host can only access services that are allowed to.

Delete a remotely trusted host.
1. Choose System Management > System Configuration > Service Management.
2. In the Remote Trust Host IP area, select a remotely trusted host, and click Delete. In the Information dialog box that is displayed, click OK.
Refresh a remotely trusted host.
1. Choose System Management > System Configuration > Service Management.
2. In the Remote Trust Host IP area, click Refresh to update the remotely trusted host to the latest information.

17.2.3 System Time

Context

To ensure communication between the router and other devices, set the accurate system time. The device support automatic system time synchronization with the NTP server or manual system time setting. The first method is recommended.

Procedure

Create a NTP server.
1. Choose System Management > System Configuration > System Time.
  Figure 17-9 System Time
2. Choose System Management > System Configuration > System Time.
3. Enter the IP address of the NTP server on the Create NTP Service page and click OK.
  
  NOTE:
  The device supports a maximum of 128 NTP servers.
Delete a NTP server.
1. Choose System Management > System Configuration > System Time.
2. In the NTP Service area, select the NTP server you want to delete and click Delete.
Refresh the NTP servers.
1. Choose System Management > System Configuration > System Time.
2. In the NTP Service area, click Refresh.
Automatically Sync with NTP Server
1. Choose System Management > System Configuration > System Time.
2. In the Date and Time Settings area, click Automatically Sync with NTP Server.
3. Click Apply. The device automatically synchronizes time with one of the NTP servers on the list.
NOTE:
- During automatic time synchronization, the device synchronizes time with the NTP server with the highest master clock level. For example, if the master clock level of NTP1 is higher than that of NTP2, the device synchronizes time with NTP1.
- If the primary clock level of the web platform is higher than the NTP servers, the web platform does not synchronize the system time with the NTP server.
- The check box of each IP address in the NTP Service area is only used to delete the corresponding NTP server.
Manually Adjust Settings
1. Choose System Management > System Configuration > System Time.
2. In the Date and Time Settings area, click Manually Adjust Settings.
3. Click the date-picker control and set the date and time.
4. Click the Time Zone drop-down list box, and select the time zone.
5. Click Apply. You can manually set the system time.

17.3 Log Management

Context

The information center works as the information hub of the system. By classifying and managing system information excepting session logs, the information center helps network administrators and developers to monitor network operation and analyze network faults. You can configure a log server, view logs, and filter logs.

17.3.1 View Logs

Context

Logs are displayed in a log list. You can view logs of a specified type and delete logs.

Procedure

Viewing logs

Choose System Management > Log Management > View Logs.
Figure 17-10 View Logs

Select a log level from the Level drop-down list box.

Table 17-9 describes log levels.

Table 17-9 Log levels

Level	Description
Emergency	A fault causes the device to fail to run normally unless it is restarted. For example, the device is restarted because of program exceptions or a memory error is detected.
Alert	A fault needs to be rectified immediately. For example, memory usage of the system reaches the upper limit.
Critical	A fault needs to be analyzed and processed. For example, the memory usage falls below the lower threshold; temperature falls below the alarm threshold; BFD detects that a device is unreachable or detects locally generated error messages.
Error	An improper operation is performed or exceptions occur during service processing. The fault does not affect services but needs to be analyzed. For example, users enter incorrect commands or passwords; error protocol packets are received from other devices.
Warning	Some events or operations may affect device running or cause service processing faults, which requires full attention. For example, a routing process is disabled; BFD detects packet loss; error protocol packets are detected.
Notification	A key operation is performed to keep the device running normally. For example, the shutdown command is run; a neighbor is discovered; protocol status changes.
Information	A normal operation is performed. For example, the display commands are run.
Debugging	A routine operation is performed, and no action is required.

Click Search.
Logs of the specified level are displayed in the log list. Table 17-10 describes parameters in the log list.
