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>.

Restrictions and guidelines

On an underlay network, the device uses the device name that you have configured for it. If you do not configure a device name for the device but automated underlay network deployment is enabled, the device uses the device name assigned by the VCF fabric feature. For more information about VCF fabric, see VCF fabric configuration in Network Management and Monitoring Configuration Guide.

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 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 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.

This feature is supported only on the default MDC. All MDCs on the device use the same system time.

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 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:

Disabling password recovery capability

About this task

Password recovery capability controls console user access to the device configuration and SDRAM from BootWare menus. For more information about BootWare menus, see the release notes.

If password recovery capability is enabled, a console user can access the device configuration without authentication to configure a new password.

If password recovery capability is disabled, console users must restore the factory-default configuration before they can configure new passwords. Restoring the factory-default configuration deletes the next-startup configuration files.

To enhance system security, disable password recovery capability.

Restrictions and guidelines

This feature is supported only on the default MDC.

(In standalone mode.) (In IRF mode.) To access the device configuration without authentication, you must connect to the active MPU and access the BootWare menu while the MPU is starting up.

Procedure

1. Enter system view.

Supported features and feature specifications vary by device operating mode.

The device can operate in one of the following modes:

· advance—Advanced mode.

· standard—Standard mode.

Restrictions and guidelines

To change the operating mode to advance, make sure the device has enough IFP ACL resources. To display the current IFP ACL resource information, use the display qos-acl resource command. For more information about this command, see ACL and QoS Command Reference.

The LSCM1GT48SC0 interface card does not support the advance mode.

A change to the device operating mode takes effect after a device reboot.

2. Set the device operating mode.

system-working-mode { advance | standard }

By default, the device operates in standard mode.

Specifying an operating mode for a service module

About operating modes for service modules

The MAC address table size and routing table size of a service module vary by operating mode. Table 1 lists the feature highlights and application scenarios of operating modes.

Table 1 Operating modes and feature highlights and application scenarios

Operating mode	Feature highlights	Recommended application scenario
normal	Uses the default MAC address table and routing table.	Common networks.
bridging	Increases the MAC address table size to provide higher Layer 2 packet forwarding performance.	A large MAC address table is required.
routing	Increases the IPv4 routing table size to provide higher Layer 3 packet forwarding performance.	A large IPv4 routing table is required.
balance	Increases the MAC address table size, ARP table size, and routing table size to provide more balanced Layer 2 and Layer 3 packet forwarding performance.	Requirements for the MAC address table, ARP table, and routing table are balanced.

‌

The enhanced operating modes include enhance, enhance-bridging, enhance-routing, and enhance-balance. An enhanced operating mode doubled the capacities of the MAC address table, ARP table, IPV4 FIB table, ND table, IPv6 FIB table, and ACL table, but decreases the forwarding performance. An enhanced operating mode is suitable for a network that has high requirements on table capacities but low requirements on forwarding performance.

The LSCM1GT48SC0 service module supports only the normal, bridging, routing, and balance modes.

You can specify an operating mode for a service module after the service module is installed in a service module slot. The configuration takes effect only after you save the running configuration and reboot the service module.

Follow these guidelines if you replace the service module in a slot that is already configured with an operating mode:

· If the new service module supports the operating mode configured for the slot, the new service module will operate in the configured operating mode.

· If the new service module does not support the operating mode configured for the slot, the new service module will operate in the default operating mode.

· To view the operating mode information about a service module, use the display switch-mode status command.

Procedure

1. Enter system view.

system-view

2. Specify an operating mode for a service module.

In standalone mode:

switch-mode slot slot-number { balance | bridging | enhance | enhance-balance | enhance-bridging | enhance-routing | normal | routing }

In IRF mode:

switch-mode chassis chassis-number slot slot-number { balance | bridging | enhance | enhance-balance | enhance-bridging | enhance-routing | normal | routing}

By default, the operating mode for a service module is normal.

Specifying the multicast forwarding mode

About this task

The following multicast forwarding modes are supported:

· enhanced—Enhanced mode. If the multicast traffic across cards is large, set the multicast forwarding mode to enhanced as a best practice.

· standard—Standard mode.

Restrictions and guidelines

This feature takes effect only after you save the running configuration and reboot the device.

This feature is not supported on the S7503X-G and S7503X-M-G switches.

This feature is supported only on the default MDC.

The device supports multicast specifying the forwarding mode only when a MPU and an interface card are installed and their index marks both start with LSCM1.

To form an IRF fabric, all IRF member devices must be configured with the same multicast forwarding mode. For more information about IRF, see Virtual Technologies Configuration Guide.

Before setting the multicast forwarding mode to enhanced, make sure the following requirements are met:

· The device is configured with local-first load sharing for link aggregation. For more information about local-first load sharing for link aggregation, see Ethernet link aggregation configuration in Layer 2—LAN Switching Configuration Guide.

· The index marks and interface numbers on the cards where the IRF physical interfaces at both ends of an IRF link are located must be the same. For more information about IRF, see Virtual Technologies Configuration Guide.

After the multicast forwarding mode is set to enhanced, only MPUs and interface cards whose index marks start with LSCM1 (except LSCM1GT48SC0) can operate correctly.

Procedure

1. Enter system view.

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 CPU core usage at 1-minute intervals, and compares the samples with CPU core usage thresholds to identify the CPU core usage status. If a sample is greater than the threshold, the device sends a log message.

· 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 to or above the minor threshold but is less than 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.

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.

Managing power supply

About power supply management

Power supplies might have problems such as overload overcurrent, overvoltage, overtemperature, and short circuit. Some power supplies use a hardware protection measure, for example, powering off the device, to protect the entire device from being damaged. The hardware protection measure helps protect the device but causes service outage. The power supply management feature can minimize service outage while protecting the device against overload problems.

The power supply management feature constantly monitors the available power and the system loads. If a potential power supply overload problem is found, this feature takes protective measures immediately to remove requirements for power supply hardware protection. Examples of protective measures include sending a notification and starting redundant power supplies.

Restrictions and guidelines

This feature is supported only on the default MDC.

Power supply management tasks at a glance

To manage power supply, perform the following tasks:

1. Enabling power supply management

2. (Optional.) Specifying the number of redundant power supplies

To avoid overload problems, you can install redundant power supplies.

3. (Optional.) Setting power supply priorities for interface cards

When available power increases, the device automatically chooses and powers on interface cards by priority. When overload problems occur, the device automatically chooses and powers off interface cards by priority.

4. (Optional.) Powering on or off a card

You can manually power on or off cards.

Enabling power supply management

1. Enter system view.

system-view

2. Enable power supply management.

In standalone mode:

power-supply policy enable

In IRF mode:

power-supply policy chassis chassis-number enable

By default, power supply management is disabled.

Specifying the number of redundant power supplies

About this task

To avoid overload problems, you can install redundant power supplies. For example, if the device requires a minimum of N power supplies to operate correctly, you can install M power supplies (M > N). The M power supplies operate in load balance mode. When a power supply fails, the load is rebalanced among the other power supplies.

After you specify the number of redundant power supplies, the device compares the maximum power consumption of a newly added card with the remaining power.

· If the remaining power is sufficient for the card, the device powers on the card.

· If the power is insufficient, the device does not power on the card. You can add power supplies or scale the number of redundant power supplies down.

Restrictions and guidelines

This feature takes effect only if power supply management is enabled.

Procedure

1. Enter system view.

system-view

2. Specify the number of redundant power supplies.

In standalone mode:

power-supply policy redundant module-count

In IRF mode:

power-supply policy chassis chassis-number redundant module-count

By default, the number of redundant power supplies is 0.

Setting power supply priorities for interface cards

About this task

After you set power supply priorities for interface cards, the power supply management feature operates as follows:

· When power becomes insufficient because of a power supply failure or removal, automatically powers off the interface cards of the lowest priorities.

· When power becomes sufficient, automatically powers on the interface cards of the highest priorities.

Restrictions and guidelines

This feature takes effect only if power supply management is enabled.

Specify higher power supply priorities for critical-service modules so they are preferentially powered.

The system automatically guarantees that an interface card that holds IRF physical interfaces receives a higher priority.

· After you bind interfaces on an interface card to IRF ports, the system automatically assigns the interface card a higher priority. You cannot use this feature to change the power supply priority for the card anymore.

· If you specify a power supply priority for an interface card and then bind its interfaces to IRF ports, the priority setting is retained but does not take effect.

Procedure

1. Enter system view.

system-view

2. Specify a power supply priority for an interface card.

In standalone mode:

power-supply policy slot slot-number priority priority

In IRF mode:

power-supply policy chassis chassis-number slot slot-number priority priority

By default, the power supply priority value for an interface card is 5.

A smaller priority value represents a higher priority.

Powering on or off a card

About this task

You can manually power on or off cards. To view the power supply status, use the display power-supply command.

Restrictions and guidelines

To power on or power off a card, you must enable power supply management first.

(In IRF mode.) To avoid IRF split, do not power off an interface card that contains the only active physical IRF port.

Powering on a card

To power on a card, execute one of the following commands in user view:

In standalone mode:

· Display the key parameters of a transceiver module, including its transceiver type, connector type, central wavelength of the transmit laser, transfer distance, and vendor name.

· Display its electronic label. The electronic label is a profile of the transceiver module and contains the permanent configuration, including the serial number, manufacturing date, and vendor name. The data was written to the transceiver module or the device's storage component during debugging or testing of the transceiver module or device.

The device regularly checks transceiver modules for their vendor names. If a transceiver module does not have a vendor name or the vendor name is not H3C, the device repeatedly outputs traps and log messages. For information about logging rules, see Network Management and Monitoring Configuration Guide.

Procedure

To verify transceiver modules, execute the following commands in any view:

· Display the key parameters of transceiver modules.

display transceiver interface [ interface-type interface-number ]

· Display the electrical label information of transceiver modules.

display transceiver manuinfo interface [ interface-type interface-number ]

Diagnosing transceiver modules

About this task

The device provides the alarm and digital diagnosis functions for transceiver modules. When a transceiver module fails or is not operating correctly, you can perform the following tasks:

· Check the alarms that exist on the transceiver module to identify the fault source.

· Examine the key parameters monitored by the digital diagnosis function, including the temperature, voltage, laser bias current, TX power, and RX power.

Procedure

To diagnose transceiver modules, execute the following commands in any view:

· Display transceiver alarms.

display transceiver alarm interface [ interface-type interface-number ]

· Display the current values of the digital diagnosis parameters on transceiver modules.

display transceiver diagnosis interface [ interface-type interface-number ]

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

· 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.

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.

Example: Scheduling a task

Network configuration

Manually triggering an active/standby switchover

About this task

If the device has two MPUs, one MPU is in active state and the other one is in standby state. Typically, the device uses the MPU that has a smaller slot number as the active MPU.

The standby MPU automatically synchronizes its running configuration with the active MPU. If the active MPU fails or is removed, the standby MPU immediately takes over to ensure device operation continuity. You can also manually trigger an active/standby switchover.

Restrictions and guidelines

This feature is supported only on the default MDC.

This feature is available only in standalone mode.

As a best practice, save the running configuration before triggering an active/standby switchover. After you trigger an active/standby switchover, the current active MPU reboots.

Procedure

1. Enter system view.

system-view

2. Manually trigger an active/standby switchover.

system switchover

Enabling the port-down feature globally

About this task

The port-down feature applies to scenarios where two devices (one active and one standby) are used for high availability. This feature shuts down all service ports on the active device immediately after both MPUs on the active device are removed or reboot abnormally. The shutdown operation ensures quick service switchover to the standby device.

Restrictions and guidelines

This feature takes effect only when no MPUs are available on the active device.

Procedure

1. Enter system view.

system-view

2. Enable the port-down feature globally.

monitor handshake-timeout disable-port

By default, the port-down feature is enabled.

Configuring an asset profile for a physical component

About this task

For easy management, this feature allows you to configure an asset profile for a physical component, such as a frame and a card.

Procedure

1. Enter system view.

system-view

2. Configure an asset profile for a physical component.

In standalone mode:

set asset-info { chassis | slot slot-number } { csn csn-number | custom name value | department department | description description | location location | service-date date | state state }

In IRF mode:

set asset-info chassis chassis-number { chassis | slot slot-number } { csn csn-number | custom name value | department department | description description | location location | service-date date | state state }

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 the device 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 ] [ force ]

In IRF mode:

reboot [ chassis chassis-number [ slot slot-number ] ] [ force ]

CAUTION:

· A device reboot might result in a service outage. Before using this command, make sure you understand its impact on the live network.

· Use the force keyword to reboot the device only when the system is faulty or fails to start up normally. A forced device reboots might cause file system damage. Before using the force keyword to reboot the device, make sure you understand its impact.

Rebooting the standby MPU

About this task

Using this feature has the same effect as specifying the slot number for the reboot slot slot-number command and executing the command. This feature does not require you to specify an argument and is easier to use.

Restrictions and guidelines

This feature is available only in standalone mode.

This feature is supported only on the default MDC.

Procedure

1. Enter system view.

system-view

2. Reboot the standby MPU.

restart standby

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, resulting in service interruption. Before using this command, make sure you understand its impact on the 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 and license files.

Restrictions and guidelines

This feature is disruptive.

This feature is supported only on the default MDC.

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 using this command, make sure you understand its impact on the 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.

Display and maintenance commands for device management configuration

Execute display commands in any view. Execute the reset scheduler logfile command in user view. Execute reset version-update-record in system view.
