2.2.2 How Long Is the Timeout Interval for an Online User Who Does Not Perform Any Operations?

The default timeout interval is 5 minutes.

The timeout interval is configurable for routers. To configure the timeout interval, perform the following operations:

  1. Run the idle-timeout minutes [ seconds ] command to configure the timeout interval in the user interface view.

  2. If AAA authentication is configured, run the local-user user-name idle-timeout minutes [ seconds ] in the AAA view to enable disconnection of a local user after you run the idle-timeout command. After the configuration is complete, the system can disconnect the user from the VTY interface when the timeout period expires. You are advised to set the timeout period to 10-15 minutes.

6711c418de1945a6a6d6c41745fe9374 NOTE:

To disable the idle cut function, run the idle-timeout 0 command.

If the idle cut function is disabled for users who log in to the VTY interface, other users may fail to obtain idle connections.

2.2.3 Does an AR Router Support Resumable FTP Download?

In versions earlier than V200R006C10, an AR router does not support resumable FTP download.

In V200R006C10 and later versions, if the router functions as an FTP client and downloads a file from the FTP server, the router supports resumable download. If the router is powered off during the download process, the file may be damaged. If you need to resume the download after the router restarts, you are advised to use the newly downloaded file to overwrite the originally downloaded file, or delete the originally downloaded file and re-download the file. Otherwise, the download may fail.

6711c418de1945a6a6d6c41745fe9374 NOTE:

Resumable FTP download takes effect for only one file. If you need to resume the download when the content of the target file changes, you are advised to use the newly downloaded file to overwrite the originally downloaded file, or delete the originally downloaded file and re-download the file. Otherwise, the file content may be incorrect.

2.2.4 How Is the V200R001C01 Flash File System Improved?

  • The self-check function is added.

  • Files are deleted in the background.

  • File read/write performance is improved.

2.2.5 What Are Shortcut Keys ESC_B and ESC_F For?

ESC_B moves the cursor forward one word, while ESC_F moves the cursor back one word.

2.2.6 When the display current-configuration Command Is Being Executed, Why Is the Message "Error:System is busy, please try again later" Displayed?

This message is displayed when the display saved-configuration command used by another user is displaying the command output.

2.2.7 How Many User Levels Does an AR Router Support?

An AR router supports user levels 0-15. The value 0 indicates the visit level, value 1 indicates the user level, value 2 indicates the configuration level, values 3 to 15 indicate the management level.

2.2.8 How Many FTP Users Can Log In to a Router Simultaneously?

Five FTP users can log in to a router simultaneously.

2.2.9 Does the AR Series Support the Web NMS?

The AR series supports the web network management system (NMS) from V200R002C01. You can use the web network management system to manage and maintain AR series.

2.2.10 What Are the Differences Between a Mini USB Interface and a Common USB Interface on the AR series?

The mini USB interface lies next to the console interface on the device. The mini USB interface supports the similar functions as the console interface and is used for configuring the device that is powered on for the first time. The USB interface is used to connect to a USB flash drive for device deployment and system file loading.

All series ARs except the AR150&160&200 series provide a mini USB interface.

2.2.11 Can the GTL License File Be Manually Modified?

No. The GTL license file is encrypted. A modified GTL license file cannot be used.

2.2.12 What Are the Functions of GTL License Invalidation Codes?

Before applying for a new license, a user must run the license revoke command to obtain the invalidation code. The user needs to apply to Huawei for a new GTL license using the invalidation code and upload the GTL license file to the storage device.

2.2.13 After the Version Is Upgraded, Do I Need to Apply for a License Again?

After the version is upgraded, apply for a license according to activated licenses before the upgrade and license support before and after the upgrade.

After the upgrade, run the display license command to check activated licenses. The Product version field indicates the license version number.
  • If V200R001 is used, only the PBX function is controlled by the license.

  • If V200R002 or later is used, voice service (SIP AG), data services, security services, CM&BEST, CT, and IVR are controlled by the license.

Then check license support before and after the upgrade. There are license differences between different versions. Table 2-28 describes mapping between product versions and supported licenses.

  • If a license has been activated before the upgrade and the licenses for required functions have been activated after the upgrade, you do not need to apply for a license.

  • If some functions are added after the upgrade, apply for a license for the new functions. For example, if WLAN AC Express is added after the device is upgraded from V200R002C00SPC200 to V200R003C00, apply for a license for WLAN AC Express.

2.2.14 Which Operations Do I Perform When a Commercial License for Capacity Expansion Is Required?

When capacity expansion is required, purchase the new control item and perform the following operations.
  1. Log in to the license management system as below.

Activate the license through the device ESN. The system combines the original license file and license file for capacity expansion and generates a new license file.

Download the new license file and activate it.

2.2.15 I Cannot Log In to the AR Router. How Is this Problem Solved?

  • By default, a user cannot log in to the AR router. You need to run the authentication-mode command in the VTY view to set the authentication mode.

  • To obtain more operation rights, run the user privilege level command in the VTY view to set the user level.

  • To enable the system to disconnect a user from the VTY interface when the timeout period expires, run the idle-timeout command in the VTY view to set the timeout period.

2.2.16 How Do I Change the License?

When you adjust the license between devices or want to change the license when the original license is incompatible on the upgraded device, run the license revoke command to revoke the existing license. The system then returns a license revocation code. You can use the license revocation code to apply for a new license file, and activate the new license file to the device during the trial period.

26263b508e8e47f7a6eaf4d1c1a40fe5 NOTICE:
Running the license revoke command causes the license file to be in trial state. The trial period is 60 days. If the trial period is reached, services will be interrupted. Exercise caution when you run the license revoke command.
  1. Before running the license revoke command, perform the following operations:

  • Contact agents and determine whether the license can be replaced. Check the time the license file can be obtained.

  • Contact Huawei technical support personnel.

If the license needs to be changed, run the license revoke command to obtain the license revocation code and provide it for agents or technical support personnel.

You can use the following methods to obtain the license revocation code:
  • Run the license revoke command. Then obtain the license revocation code in the displayed message:

    <Huawei> license revokeWarning: This operation will cause LCS into the TRIAL state. Continue? [Y/N]:y     
    Info: License revoke success. The revoke ticket is: LIC2011021100B400:C20824861A2C0C03B9803D05FC40783D36B76301.
  • After the license is revoked, run the display license revoke-ticket command to view the license revocation code.

    <Huawei> display license revoke-ticket                           Info: The revoke ticket is: LIC2011021100B400:C20824861A2C0C03B9803D05FC40783D36B76301

After obtaining the new license file, store the license file in the root directory of the flash memory on the device through FTP. Run the license active file-name command to activate the license.

2.2.17 A User Is Redirected to Another Device Using the Asynchronous Serial Port. How Does the User Return to the Login Page?

Press Ctrl+] to return to the login page.

2.2.18 Do I Need to Pay Attention to the Mapping Between Activation IDs and Device ESNs?

When you obtain a license file for different models of the same series (for example, AR1220V and AR1220W) using the activation ID and ESN at the website, you do not need to pay attention to the mapping between activation IDs and device ESNs.

When you obtain a license file for different models of the different series (for example, AR1220, AR2240, and AR2240C) using the activation ID and ESN at the website, the activation ID is valid for the same series.

6711c418de1945a6a6d6c41745fe9374 NOTE:

When applying for a license, ensure that the ESN is case sensitive. If the case of the device ESN is different from that of the ESN in the license file, the license file cannot be activated.

2.2.19 Do I Need to Pay Attention to the Mapping Between Activation IDs and Device Models?

In V2R1, you do not need to pay attention to the mapping between activation IDs and device models.

In later versions of V2R2:
  • For capacity licenses such as AR CT license and AR IVR license, you do not need to pay attention to the mapping between activation IDs and device models.

  • For features licenses, such as AR150&160&200 value-added service package for data services and AR1200 value-added service package for security services,you need to pay attention to the mapping between activation IDs and device models.

2.2.20 How Do I Log in to the Device Using BootROM If I Forget the Console Login Password

The console interface on RouterA connects to the PC and the console login password is forgotten. It is required that BootROM be used to log in to the device. This example applies to V200R003C00 and later versions, and all AR models.

2.2.29 What Should I Do If the Account Is Locked?

By default, a locked account is automatically unlocked after 5 minutes. You can wait until the account is automatically unlocked, and enter the correct user name and password to log in to the device again.

You can also log in to the device using the CLI mode when the account is locked, and run the local-user user-name state active command in the AAA view to unlock the account.

2.2.30 How Do I Obtain the Web Page File?

The system software contains the web page file. After new system software is loaded to the device, the web page file web.zip is directly decompressed from the system software and saved to the memory.

2.2.31 How Do I Change the Port Number for Web Platform Login?

The default port number of the HTTPS server is 443. If you access and control the device through the web platform, you do not need to specify the port number. If the default port number is used, attackers may access this port continuously, consuming bandwidth resources and degrading security performance of the server. As a result, authorized users cannot access the device. If the default port number is used by another service, users cannot log in to the device through the web platform.

You can run the http secure-server port port-number command in the system view to reconfigure the port number of the HTTPS server.

2.2.32 Which Interface Is Configured with the Default Management IP Address?

The device has a default management IP address configured and the web system enabled from a specified version before it is delivered. Table 2-32 lists detailed information.

2.2.34 How Do I Force an Online User to Go Offline?

You can run the free user-interface { ui-number | ui-type ui-number1 } command to remove a user from a specified user interface, that is, disconnect the user from the device.

This command does not take effect for the current user. For example, if the user interface of the current user is VTY 2, the free user-interface vty 2 command does not take effect and the system displays an error message.

<Huawei> free user-interface 0Warning: User interface Console1 will be freed. Continue? [Y/N]:y

2.2.35 How Do I Define the Command Level?

The administrator can run the command-privilege level level view view-name command-key command to set the command level in a specified view. This configuration enables a lower-level user to use some high-level commands, or raises the command level to improve device security.

26263b508e8e47f7a6eaf4d1c1a40fe5 NOTICE:

It is recommended that you do not change the default command level without the guidance of professionals. Otherwise, it may result in inconvenience for operation and maintenance and bring about security problems.

2.2.36 Why Does the Available Space on a Storage Medium Not Change After a File Is Deleted?

If you specify the /unreserved parameter when running the delete [ /unreserved ] [ /force ] { filename | devicename } command to delete a specified file on a storage medium, the file is deleted permanently and cannot be restored.

If you do not specify the /unreserved parameter when running the delete [ /unreserved ] [ /force ] { filename | devicename } command to delete a specified file on a storage medium, the file is moved to the recycle bin and is not deleted permanently. The file still occupies storage space on the storage medium.

You can run the dir /all command to view information about all files, including deleted files marked with square brackets ([ ]). To restore deleted files, run the undelete { filename | devicename } command.

To remove a file from the recycle bin to release the occupied storage space, run the reset recycle-bin [ filename | devicename ] command.
