Configuring the device name
About this task
A device name (also called hostname) identifies a device in a network and is used in CLI view prompts. For example, if the device name is Sysname, the user view prompt is <Sysname>.
Procedure
1. Enter system view.
system-view
sysname sysname
By default, the device name is H3C.
Configuring the system time
About the system time
Correct system time is essential to network management and communication. Configure the system time correctly before you run the device on the network.
The device can use the following methods to obtain the system time:
· Uses the locally set system time, and then uses the clock signals generated by its built-in crystal oscillator to maintain the system time.
· Periodically obtains the UTC time from an NTP or PTP source, and uses the UTC time, time zone, and daylight saving time to calculate the system time. For more information about NTP and PTP, see Network Management and Monitoring Configuration Guide.
The system time calculated by using the UTC time from a time source is more precise.
Restrictions and guidelines for configuring the system time
The system time configured by using the clock datetime command takes effect immediately. The time zone or daylight saving time, whether configured or not, are not taken into account.
If you configure or change the time zone or daylight saving time after the device obtains the system time, the device recalculates the system time. To view the system time, use the display clock command.
You can configure the device to use both methods to obtain the system time. For time consistency, however, configure the device to use only one of the methods to obtain the system time. If you configure the device to use both methods, the device uses the manually set system time or the periodically obtained UTC time, whichever is obtained later.

Displaying copyright information
Enabling copyright statement display
About this task
This feature enables the device to display the copyright statement in the following situations:
· When a Telnet or SSH user logs in.
· When a console dial-in user quits user view. This is because the device automatically tries to restart the user session.
Figure 1 shows the copyright statement.
If you disable displaying the copyright statement, the device does not display the copyright statement in any situations.

Configuring banners
About this task
Banners are messages that the system displays when a user logs in.
The system supports the following banners:
· Legal banner—Appears after the copyright statement.
· Message of the Day (MOTD) banner—Appears after the legal banner and before the login banner.
· Login banner—Appears only when password or scheme authentication is configured.
· Shell banner—Appears for a user when the user accesses user view.
The system displays the banners in the following order: legal banner, MOTD banner, login banner, and shell banner.
Banner input methods
You can configure a banner by using one of the following methods:
· Input the entire command line in a single line.
The banner cannot contain carriage returns. The entire command line, including the command keywords, the banner, and the delimiters, can have a maximum of 511 characters. The delimiters for the banner can be any printable character but must be the same. You cannot press Enter before you input the end delimiter.
For example, you can configure the shell banner "Have a nice day." as follows:
<System> system-view
[System] header shell %Have a nice day.%
· Input the command line in multiple lines.
The banner can contain carriage returns. A carriage return is counted as two characters.
To input a banner configuration command line in multiple lines, use one of the following methods:
¡ Press Enter after the final command keyword, type the banner, and end the final line with the delimiter character %. The banner plus the delimiter can have a maximum of 1999 characters.
For example, you can configure the banner "Have a nice day." as follows:
<System> system-view
[System] header shell
Please input banner content, and quit with the character '%'.
Have a nice day.%
¡ After you type the final command keyword, type any printable character as the start delimiter for the banner and press Enter. Then, type the banner and end the final line with the same delimiter. The banner plus the end delimiter can have a maximum of 1999 characters.
For example, you can configure the banner "Have a nice day." as follows:
<System> system-view
[System] header shell A
Please input banner content, and quit with the character 'A'.
Have a nice day.A
¡ After you type the final command keyword, type the start delimiter and part of the banner. Make sure the final character of the final string is different from the start delimiter. Then, press Enter, type the rest of the banner, and end the final line with the same delimiter. The banner plus the start and end delimiters can have a maximum of 2002 characters.
For example, you can configure the banner "Have a nice day." as follows:
<System> system-view
[System] header shell AHave a nice day.
Please input banner content, and quit with the character 'A'.
A
Procedure
1. Enter system view.
system-view
2. Configure the legal banner.
header legal text
3. Configure the MOTD banner.
header motd text
4. Configure the login banner.
header login text
5. Configure the shell banner.
header shell text
Scheduling a task
About task scheduling
You can schedule the device to automatically execute a command or a set of commands without administrative interference.
You can configure a periodic schedule or a non-periodic schedule. A non-periodic schedule is not saved to the configuration file and is lost when the device reboots. A periodic schedule is saved to the startup configuration file and is automatically executed periodically.
Restrictions and guidelines
· To assign a command (command A) to a job, you must first assign the job the command or commands for entering the view of command A.
· Make sure all commands in a schedule are compliant to the command syntax. The system does not check the syntax when you assign a command to a job.
· A schedule cannot contain any one of these commands: telnet, ftp, ssh2, and monitor process.
· A schedule does not support user interaction. If a command requires a yes or no answer, the system always assumes that a Y or Yes is entered. If a command requires a character string input, the system assumes that either the default character string (if any) or a null string is entered.
· A schedule is executed in the background, and no output (except for logs, traps, and debug information) is displayed for the schedule.
Procedure
1. Enter system view.
system-view
2. Create a job.
scheduler job job-name
3. Assign a command to the job.
command id command
By default, no command is assigned to a job.
You can assign multiple commands to a job. A command with a smaller ID is executed first.
4. Exit to system view.
quit
5. Create a schedule.
scheduler schedule schedule-name
6. Assign a job to the schedule.
job job-name
By default, no job is assigned to a schedule.
You can assign multiple jobs to a schedule. The jobs will be executed concurrently.
7. Assign user roles to the schedule.
user-role role-name
By default, a schedule has the user role of the schedule creator.
You can assign a maximum of 64 user roles to a schedule. A command in a schedule can be executed if it is permitted by one or more user roles of the schedule.
8. Specify the execution time for the schedule.
Choose one option as needed:
¡ Execute the schedule at specific points of time.
time at time date
time once at time [ month-date month-day | week-day week-day&<1-7> ]
¡ Execute the schedule after a period of time.
time once delay time
¡ Execute the schedule at the specified time on every specified day in a month or week.
time repeating at time [ month-date [ month-day | last ] | week-day week-day&<1-7> ]
¡ Execute the schedule periodically from the specified time on.
time repeating [ at time [date ] ] interval interval
By default, no execution time is specified for a schedule.
The time commands overwrite each other. The most recently executed command takes effect.
9. (Optional.) Set the schedule log file size limit.
scheduler logfile size value
By default, the schedule log file size limit is 16 KB.
The schedule log file stores log messages for execution results of commands in jobs. After the limit is reached, the system deletes the oldest log messages to store the new log messages. If the remaining space of the log file is not enough for a single log message, the system truncates the message and does not store the extra part.
