a few basic but useful maintenance commands

To make it easy to maintain Huawei’s device it is recommended to configure proper time. You can do it manually or configure NTP protocol to force the device to use reference time from external servers. I will also show you how to configure header for login information and how to execute the specified batch file.

Setting of time zone:

clock timezone time-zone-name { add | minus } offset

Let’s take Poland time zone as an example.

<NE40E>clock timezone labnario add 1

 Setting of daylight-saving-time:

clock daylight-saving-time time-zone-name repeating start-time { { { first | second | third | fourth | last } weekday month } | start-date } end-time { { { first | second | third | fourth | last } weekday month } | end-date } offset

Using the “clock daylight-saving-time” command, you can configure the name, start time and end time of the daylight saving time. Taking Poland as an exapmple we add 1 hour during summer time:

<NE40E>clock daylight-saving-time labnario repeating 02:00 last Sun Mar 03:00 last Sun Oct 01:00

Setting of actual time:

<NE40E>clock datetime 18:00 2011-11-03

You can display clock information using “display clock” command.

NTP external servers:

If you want to use external NTP servers, for time synchronization, you can configure them in the following way:

[NE40E]ntp-service unicast-server x.x.x.x source-interface interface name
[NE40E]ntp-service unicast-server y.y.y.y source-interface interface name

You can display status of NTP using “display ntp-service status” command.

I only showed you basic NTP configuration. More details you can find in specific product documentation.

Header login configuration:

You can configure header login information in the 2 ways:

As a text:

[NE40E]header login information "
Info:The banner text supports 220 characters max, including the start and the end character.If you want to enter more than this, use banner file instead.
Input banner text, and quit with the character '"':
****************************************

[NE40E]

Using a file stored in CF card:

[NE40E]header login file labnario.txt

Execute name.bat

Sometimes, instead of putting many commands in CLI, it is easier and faster to use batch file. You can create such batch (suffixed with “.bat”) file with a set of commands inside and then upload it to CF card by FTP. Then you can use “execute name.bat” command to start the file.
