This chapter describes how to configure basic device parameters and manage the device. You can perform the configuration tasks in this chapter in any order.

Device management restrictions and guidelines

After being powered on, a card takes some time to start up and complete configuration and data restoration and synchronization. Before configuring the card, use the display device and display system stable state commands to verify that the card is in Normal and Stable states. Failing to follow this rule might cause configuration failures and even device exceptions.

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

2. Configure the device name.

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 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 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

After you execute 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

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 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:

<Sysname> system-view

[Sysname] 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:

<Sysname> system-view

[Sysname] 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:

<Sysname> system-view

[Sysname] 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:

Monitoring CPU usage

About this task

To monitor CPU usage, the device performs the following operations:

· Samples CPU usage at 1-minute intervals, and compares the samples with CPU usage thresholds to identify the CPU usage status and send alarms or notifications accordingly.

· Samples and saves CPU usage at a configurable interval if CPU usage tracking is enabled. You can use the display cpu-usage history command to display the historical CPU usage statistics in a coordinate system.

The device supports the following CPU usage thresholds:

· Minor threshold—If the CPU usage increases above the minor threshold but is less than or equal to the severe threshold, the CPU usage enters minor alarm state. The device sends minor alarms periodically until the CPU usage increases above the severe threshold or the minor alarm is removed.

· Severe threshold—If the CPU usage increases above the severe threshold, the CPU usage enters severe alarm state. The device sends severe alarms periodically until the severe alarm is removed.

· Recovery threshold—If the CPU usage decreases below the recovery threshold, the CPU usage enters recovered state. The device sends a recovery notification.

CPU usage alarms and notifications can be sent to NETCONF, SNMP, and the information center to be encapsulated as NETCONF events, SNMP traps and informs, and log messages. For more information, see NETCONF, SNMP, and information center in Network Management and Monitoring Configuration Guide.

Monitoring kernel memory fragments

About this task

A running kernel thread's process requires memory allocation from the system. The system allocates and releases this memory as a whole. If the process is still running and some memory blocks have been used but are no longer used, these memory blocks will not be released in advance. These free but currently unusable memory blocks are also referred to as memory fragments. This feature allows the device to monitor the kernel memory fragment ratio at intervals. If the kernel memory fragment ratio increases to or above the alarm threshold, the kernel memory usage is low and an alarm notification is generated. If the kernel memory fragment ratio decreases below the alarm threshold, the kernel memory usage returns to the normal state and a recovery notification is generated.

Procedure

1. Enter system view.

system-view

2. Set the kernel memory fragment ratio alarm threshold.

Configuring resource monitoring

About this task

The resource monitoring feature enables the device to monitor the available amounts of types of resources, for example, the space for ARP entries. The device samples the available amounts periodically and compares the samples with resource depletion thresholds to identify the resource depletion status.

The device supports a minor resource depletion threshold and a severe resource depletion threshold for each supported resource type.

· If the available amount is equal to or less than the minor resource depletion threshold but greater than the severe resource depletion threshold, the resource type is in minor alarm state.

· If the available amount is equal to or less than the severe resource depletion threshold, the resource type is in severe alarm state.

· If the available amount increases above the minor resource depletion threshold, the resource type is in recovered state.

When a resource type enters severe alarm state, the device issues a severe alarm. If the resource type stays in severe alarm state, the device resends severe alarms periodically.

When a resource type enters minor alarm state, the device issues a minor alarm. If the resource type stays in minor alarm state or changes from severe alarm state to minor alarm state, the device identifies whether resending of minor resource depletion alarms is enabled. If the feature is disabled, the device does not issue additional minor alarms. If the feature is enabled, the device resends minor alarms periodically.

Resource depletion alarms can be sent to NETCONF, SNMP, and the information center to be encapsulated as NETCONF events, SNMP traps and informs, and log messages. For more information, see NETCONF, SNMP, and information center in Network Management and Monitoring Configuration Guide.

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 for task scheduling

· The default system time is always restored at reboot. To make sure a task schedule can be executed as expected, reconfigure the system time or configure NTP after you reboot the device. For more information about NTP, see Network Management and Monitoring Configuration Guide.

· 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.

· You can assign multiple 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.

The security log manager user role is mutually exclusive with other user roles. That is, if the security log manager user role has been assigned, the system will automatically remove the existing other user roles. If the other user roles have been assigned, the system will automatically remove the existing security log manager user role.

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.

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 at intervals 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 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.

Example: Scheduling a task

Network configuration

Isolating switching fabric modules

About this task

Isolating a switching fabric module isolates the module from the data plane. An isolated switching fabric module continues to communicate with the MPU, and can forward traffic immediately after the isolation is canceled. The isolation does not affect protocol packet parsing and protocol calculation on the control plane.

Restrictions and guidelines

You can isolate switching fabric modules to identify whether switching fabric modules can forward traffic correctly.

Before replacing a switching fabric module, you can isolate the module to prevent packet loss.

Do not reboot the device when a switching fabric module is isolated.

To use an isolated switching fabric module or channel, use the undo switch-fabric isolate command to cancel the isolation.

This feature does not take effect for CSPC-GE16XP4L-E, CSPC-GE24L-E, CSPC-GP24GE8XP2L-E, CSPEX-1104-E, and SPEX-1204 cards. Traffic of these cards go through an isolated switching fabric module or channel as normal.

Procedure

1. Enter system view.

system-view

2. Isolate a switching fabric module or channel.

In standalone mode:

switch-fabric isolate slot slot-number

In IRF mode:

switch-fabric isolate chassis chassis-number slot slot-number

By default, a switching fabric module is not isolated and can forward traffic.

CAUTION:

· Isolate a switching fabric module only if required. If the device has multiple switching fabric modules, isolating a switching fabric module or channel decreases the forwarding bandwidth and reduces the forwarding performance.

· Do not isolate the only switching fabric module of the device.

‌

Specifying the number of automatically isolated switching fabric modules

About this task

After you configure this feature, the system automatically isolates switching fabric modules when a failure is detected on switching fabric modules. If the device has four switching fabric modules, a maximum of two switching fabric modules can be isolated.

Rebooting the device

About device reboot

The following device reboot methods are available:

· Schedule a reboot at the CLI, so the device automatically reboots at the specified time or after the specified period of time.

· Immediately reboot the device at the CLI.

During the reboot process, the device performs the following operations:

a. Resets all of its chips.

b. Uses the BootWare to verify the startup software package, decompress the package, and load the images.

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

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 [ slot slot-number [ cpu cpu-number | subslot subslot-number ] ] [ force ]

In IRF mode:

reboot [ chassis chassis-number [ slot slot-number [ cpu cpu-number | subslot subslot-number ] ] ] [ force ]

Scheduling a device reboot

Restrictions and guidelines

(In standalone mode.) The automatic reboot configuration is canceled if an active/standby switchover occurs.

(In IRF mode.) The automatic reboot configuration is effective on all member devices. It will be canceled if a switchover between the global active MPU and a global standby MPU 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.

CAUTION:

This task enables the device to reboot at a scheduled time, which causes service interruption. Before configuring this task, make sure you fully understand its impact on your live network.

‌

Restoring the factory-default configuration

About this task

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.

Procedure

1. Execute the following command in user view to restore the factory-default configuration for the device:

restore factory-default

2. Reboot the device.

reboot

CAUTION:

This command restores the device to the factory default settings. Before executing this command, make sure you fully understand its impact on your live network.

‌

When the command prompts you to choose whether to save the running configuration, enter N. If you choose to save the running configuration, the device loads the saved configuration at startup.
