Hi,there.
Q: Power consumptions of the MA5616 and MA5818?
A: To query the power consumption of an entire device or boards, visit http://support.huawei.com/onlinetoolsweb/network_hdcfg/toBrowser?pDomain=Access Network&subDomain=MDU&domain=1&lang=en&hidden=.
Q: The ADSL port frequently goes offline.
A: You can check whether the alarm 0x3d310032 (The port can not be activated by auto reset after offline) is generated. If the alarm is generated, clear it with reference to the alarm handling procedure in the Alarm Reference.
Q: The optical module connected to the upstream port of the MA5616 cannot work properly.
A: You can run the display port mode command to check whether the working mode of the upstream port is consistent with the actual working mode of the optical module. If not, run the port mode command to modify the working mode of the upstream port.
Q: How to configure and query fast channel mode and maximum interleave delay of a VDSL2 board?
A: You can run the xdsl fast-latency-path-config command to configure maximum interleave delay corresponding to VDSL2 fast channel mode (fast mode), and run the display xdsl global-config command to query the global xDSL configuration, including the maximum interleave delay.
Q: How do I back up data?
A: You can run the diagnose command to enter diagnose mode, and then run the backup data command to save the backup data to the specified storage device such as a computer through TFTP, FTP, or SFTP.
Q: How do I export all configuration data of a device?
A: You can run the display current-configuration command to query the configuration commands that are valid in the system. You can run the backup configuration command to back up the configuration file in the flash memory of the control board to a specified server or terminal.
Q: How do I configure the SNMP Trap on the product?
A: You can run the snmp-agent target-host trap-hostname command to configure related parameters or obtain the MA5626 product documentation from Huawei official website, and choose Configuration > Basic Configuration > NMS Configuration to obtain detailed NMS configuration information, such as SNMP Trap.
Q: Why does the system display a message indicating that the remote host rejects the ONU login? How do I configure access control?
A: You can run the display sysman ip-access command to check whether permitted address segments are configured and run the display sysman ip-refuse command to check whether denied address segments are configured.
If the IP address of an access device is in the denied IP address segments, run the undo sysman ip-refuse command to delete the IP address of the access device from the denied IP address list.
Q: How do I clear device data?
A: You can use the erase flash data command to erase the configuration data from the flash memory of the control board. When the configured data is saved to the flash memory, you can run this command to restore the database to the initial state, namely, to erase the data configured by the user. After the data is erased successfully, all the original configuration data in the flash memory of the control board is lost.
Note:
After the preceding command is executed, all the configuration data in the system will be erased. Exercise caution.
Q: How do I configure a firewall?
A: You can configure a firewall blacklist, ACL-based packet filtering firewall, firewall blacklist + advanced ACL rules, and protection against unauthorized logins. Select a scheme based on your requirements.
Obtain the product documentation from Huawei official website. Choose Configuration > Basic Configuration > NMS Configuration to obtain detailed NMS configuration information, such as SNMP Trap.
Q: How do I add a device user or account?
A: You can run the terminal user name command to add a user who has the permission to access and operate a device or change the super user name.
You can run the undo terminal user name command to delete a device user. After being deleted, the user cannot access, configure, or manage the device.
The super user (root) and administrators can add users of lower levels. To be specific:
- The super user can add administrators, operators, and common users.
- Administrators can add only operators and common users.
Q: Why the status of a board is displayed as autoload?
A: When a board is started for the first time, it takes some time to load board software. During this period, the status of the board is displayed as autoload. After the loading is complete, the status of the board is displayed as normal.
I hope it will be helpful for you. Thank you!
