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 one of 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 source, and uses the UTC time, time zone, and daylight saving time to calculate the system time. For more information about NTP, 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

After you configure the clock protocol none command, the clock datetime command determines the system time, whether or not the time zone or daylight saving time has been configured.

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.

System time configuration tasks at a glance

To configure the system time, perform the following tasks:

1. Configuring the system time

Choose one of the following tasks:

¡ Setting the system time at the CLI

Configuring banners

About banners

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. To continue login, the user must enter Y or press Enter. To quit the process, the user must enter N. Y and N are case insensitive.

· 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 before the user enters 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'.

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 configured command takes effect.

9. (Optional.) Set the size of the job execution log file.

scheduler logfile size value

By default, the size of the job execution log file is 16 KB.

The job execution log file stores the execution information of jobs. If the file is full, old records are deleted to make room for new records. If the size of the log information to be written to the file is greater than the file size, the excessive information is not written to the file.

Example: Scheduling a task

c. Initializes the system.

· Power off and then power on the device. This method might cause data loss, and is the least-preferred method.

Using the CLI, you can reboot the device from a remote host.

Restrictions and guidelines for device reboot

A device reboot might result in a service outage.

For data security, the device does not reboot while it is performing file operations.

Rebooting devices immediately at the CLI

Prerequisites

Perform the following steps in any view:

1. Verify that the next-startup configuration file is correctly specified.

display startup

For more information about the display startup command, see Fundamentals Command Reference.

2. Verify that the startup image files are correctly specified.

display boot-loader

If one main startup image file is damaged or does not exist, you must specify another main startup image file before rebooting the device.

For more information about the display boot-loader command, see Fundamentals Command Reference.

3. Save the running configuration to the next-startup configuration file.

save

To avoid configuration loss, save the running configuration before a reboot.

For more information about the save command, see Fundamentals Command Reference.

Procedure

To reboot the device immediately at the CLI, execute one of the following commands in user view:

In standalone mode:

reboot [ force ]

In IRF mode:

reboot [ slot slot-number ] [ force ]

Scheduling a device reboot

Restrictions and guidelines

(In IRF mode.) The automatic reboot configuration takes effect on all member devices. It will be canceled if a master/subordinate switchover occurs.

The device supports only one device reboot schedule. If you execute the scheduler reboot command multiple times, the most recent configuration takes effect.

Procedure

To schedule a reboot, execute one of the following commands in user view:

· scheduler reboot at time [ date ]

· scheduler reboot delay time

By default, no device reboot time is specified.

Restoring the factory-default configuration

About restoring the factory-default configuration

If you want to use the device in a different scenario or you cannot troubleshoot the device by using other methods, use this task to restore the factory-default configuration.

This task does not delete .bin files and license files.

Restrictions and guidelines

CAUTION:

This feature reboots the device forcibly to restore the factory-default configuration.

Procedure

To restore the factory-default configuration for the device, execute the following command in user view:

restore factory-default
