Usage guidelines

This command is supported only on the default MDC.

Correct system time is essential to network management and communication. You must configure the system time correctly before you run the device on the network.

For the device to use the local system time, execute the clock protocol none command and this command in turn. The specified system time takes effect immediately. Then, the device uses the clock signals generated by its built-in crystal oscillator to maintain the system time.

If you set the time zone or daylight saving time after you configure this command, the device recalculates the system time. To view the system time, use the display clock command.

Examples

# Set the system time to 08:08:08 01/01/2012.

<Sysname> clock datetime 8:8:8 1/1/2012

# Set the system time to 08:10:00 01/01/2012.

<Sysname> clock datetime 8:10 2012/1/1

Parameters

none: Uses the system time set by using the clock datetime command.

ptp: Uses PTP to obtain the UTC time. You must configure PTP correctly. For more information about PTP and PTP configuration, see Network Management and Monitoring Configuration Guide.

ntp: Uses NTP to obtain the UTC time. You must configure NTP correctly. For more information about NTP and NTP configuration, see Network Management and Monitoring Configuration Guide.

mdc mdc-id: Specifies the MDC to be used for time synchronization. The value range is 1 to 8.

Usage guidelines

This command is supported only on the default MDC.

Correct system time is essential to network management and communication. You must configure the system time correctly before you run the device on the network.

The device can use the locally set system time, or obtain the UTC time from a time source on the network and calculate the system time.

· If you configure the clock protocol none command, the device uses the locally set system time. The device then uses the clock signals generated by its built-in crystal oscillator to maintain the system time.

· If you configure the clock protocol { ntp | ptp } command, the device obtains the UTC time through NTP or PTP and calculates the system time. The device then periodically synchronizes the UTC time and recalculates the system time.

The system time calculated by using the UTC time from an NTP or PTP time source is more precise.

If you execute this command multiple times, the most recent configuration takes effect.

If you set the time zone or daylight saving time after you configure this command, the device recalculates the system time. To view the system time, use the display clock command.

All MDCs on the device use the same system time. After obtaining the system time from an MDC, the device automatically synchronizes the system time to the other MDCs.

Usage guidelines

After CPU usage monitoring is enabled, the system regularly samples CPU usage and saves the samples to the history record buffer. This command displays the most recent 60 samples in a coordinate system as follows:

· The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.

· The horizontal axis represents the time.

· Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at a specific time represents the CPU usage at that time.

Executing this command on an MDC displays the historical CPU usage statistics for the MDC.

display diagnostic-information

Use display diagnostic-information to display or save operating information for features and hardware modules.

Syntax

display diagnostic-information [ hardware | infrastructure | l2 | l3 | service ] [ key-info ] [ filename ]

Views

Any view

Predefined user roles

network-admin

network-operator

mdc-admin

mdc-operator

Parameters

hardware: Specifies hardware-related operating information.

infrastructure: Specifies operating information for the fundamental features.

l2: Specifies operating information for the Layer 2 features.

l3: Specifies operating information for the Layer 3 features.

service: Specifies operating information for Layer 4 and upper-layer features.

key-info: Displays or saves only critical operating information. The device might have a large amount of operating information if an exception occurs or after the device runs a long period of time. Specifying this keyword reduces the command execution time and helps you focus on critical operating information. If you do not specify this keyword, the command displays or saves both critical and non-critical operating information.

filename: Saves the information to a file. The filename argument must use the .tar.gz suffix. If you do not specify this argument, the command prompts you to choose whether to save the information to a file or display the information.

Usage guidelines

You can use one of the following methods to collect operating statistics for diagnostics and troubleshooting:

· Use separate display commands to collect operating information feature by feature or module by module.

· Use the display diagnostic-information command to collect operating information for multiple or all features and hardware modules.

To save storage space, the display diagnostic-information command automatically compresses information before saving information to a file. To view the file content:

1. Use the tar extract command to extract the file.

2. Use the gunzip command to decompress the extracted file.

3. Use the more command to view the content of the decompressed file.

If you abort the display diagnostic-information command, the gunzip command might not be able to decompress the extracted file. To decompress the extracted file, export the extracted file to a PC that is running Linux, and use the gunzip -c command.

If you do not specify any feature parameters, this command displays or saves the operating information for all features and modules.

If you do not specify a file name for the command, the system prompts you to choose whether to display or save the information. If you choose to save the information, the system automatically assigns a file name and displays the file name in brackets. For file name uniqueness, the file name includes the device name and the current system time. If the device name contains any of the following special characters, the system uses an underscore (_) to replace each special character: forward slashes (/), backward slashes (\), colons (:), asterisks (*), question marks (?), less than signs (<), greater than signs (>), and pipeline signs (|). For example, if the device name is A/B, the device name in the file name will be A_B, as in flash:/diag_A_B_20160101-000438.tar.gz.

This command does not support the |, >, or >> option.

While the device is executing this command, do not execute any other commands. Executing other commands might affect the collected operating information.

Parameters

mdc { mdc-id | all }: Specifies an MDC by its ID or specifies all MDCs.

summary: Displays brief information about system stability and status, including system status, redundancy status, and NSR status. If you do not specify this keyword, the command displays detailed information about system status, redundancy status, and CPU role and status.

Usage guidelines

If you do not specify an MDC, this command displays stability information for the system.

Before performing an ISSU or a switchover, execute this command multiple times to identify whether the system is operating stably. If the value of the System State field is not Stable, you cannot perform an ISSU. If the value of the Redundancy Stable field is not Stable, you cannot perform a switchover.

The device or MDC startup process takes some time. If the values of the status fields do not change to Stable, execute this command multiple times to identify the devices or MDCs that are not in Stable state. You can also use other commands to identify the faulty components. For example:

· Use the display device command to identify the device operating status.

· Use the display ha service-group command to display the status of HA service groups and identify the groups in batch backup state.

· Use the display system internal process state command in probe view to display service operating status.

Examples

# Display brief information about system stability and status.

<Sysname> display system stable state summary

Parameters

minor minor-value: Specifies the minor alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the minor-value argument. This threshold must be equal to or less than the normal state threshold. Setting this threshold to 0 disables the minor alarm feature.

severe severe-value: Specifies the severe alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the severe-value argument. This threshold must be equal to or less than the minor alarm threshold. Setting this threshold to 0 disables the severe alarm feature.

critical critical-value: Specifies the critical alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the critical-value argument. This threshold must be equal to or less than the severe alarm threshold. Setting this threshold to 0 disables the critical alarm feature.

normal normal-value: Specifies the normal state threshold. To view the value range for this threshold, enter a question mark (?) in the place of the normal-value argument. This threshold must be equal to or less than the total memory size.

chassis chassis-number slot slot-number: Specifies a card on a cluster member device. The chassis-number argument represents the member ID of the cluster member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command sets free-memory thresholds for the global active MPU.

cpu cpu-number: Specifies a CPU by its number.

Usage guidelines

This command is supported only on the default MDC.

To ensure correct operation and improve memory efficiency, the system monitors the amount of free memory space in real time. If the amount of free memory space decreases to or below the minor, severe, or critical alarm threshold, the system issues an alarm to affected service modules or processes.

You can use the display memory command to display memory usage information.

For more information about the alarm thresholds, see Fundamentals Configuration Guide.

Usage guidelines

This command is supported only on the default MDC.

Password recovery capability controls console user access to the device configuration and SDRAM from BootWare menus.

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

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.

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.

Availability of BootWare menu options depends on the password recovery capability setting. For more information, see the release notes.

Parameters

chassis chassis-number: Specifies a cluster member device by its member ID. If you do not specify a cluster member device, the command reboots all cluster member devices.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, the command reboots the cluster member device.

subslot subslot-number: Specifies a subcard by its subslot number. If you do not specify a subslot number, the command reboots the slot.

force: Reboots the device immediately without performing software or hard disk check. If this keyword is not specified, the system first identifies whether the reboot might result in data loss or a system failure. For example, the system identifies whether the main system software image file exists and whether a write operation is in progress on a storage medium. If the reboot might cause problems, the system does not reboot the device.

Usage guidelines

CAUTION:

· A reboot might interrupt network services.

· Use the force keyword only when the device fails or a reboot command without the force keyword cannot perform a reboot correctly. A reboot command with the force keyword might result in file system corruption because it does not perform data protection.

‌

If the main startup software images are corrupt or missing, you must re-specify a set of main startup software images before executing the reboot command.

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

If the cluster has only one MPU, rebooting the MPU reboots the entire cluster. If the cluster has a global standby MPU and the MPU is operating correctly, rebooting the global active MPU triggers a switchover.

To ensure correct operation of the cluster and cards, do not trigger a switchover by rebooting the global active MPU if no global standby MPUs are in Stable state. To view the status of global standby MPUs, execute the display system stable state command.

Examples

# Reboot the device. Save the running configuration at prompt.

<Sysname> reboot

Usage guidelines

A schedule must have one or more user roles. A command in a schedule can be executed if it is permitted by one or more user roles of the schedule. For more information about user roles, see the RBAC configuration in Fundamentals Configuration Guide.

A schedule can have a maximum of 64 user roles. After the limit is reached, you cannot assign additional user roles to 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.
