Usage guidelines

CAUTION:

This command changes the system time, which affects the execution of system time-related features (for example, scheduled tasks) and collaborative operations of the device with other devices (for example, log reporting and statistics collection). Before executing this command, make sure you fully understand its impact on your live network.

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 execute 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

Predefined user roles

network-admin

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 an MDC by its ID.

Usage guidelines

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 execute 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 execute 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 execute this command, the device recalculates the system time. To view the system time, use the display clock command.

Parameters

job job-id: Specifies a process by its ID in the range of 1 to 2147483647. If you do not specify a process, this command displays the statistics for the entire system's CPU usage (the total CPU usage of all processes). To view the IDs and names of the running processes, use the display process command. For more information, see Network Management and Monitoring Configuration Guide.

slot slot-number: Specifies a card by its slot number. If you specify a process but do not specify a card, this command displays the statistics for the process on the active MPU. If you do not specify any options, this command displays the statistics for all processes on all cards.

cpu cpu-number: Specifies a CPU by its number. If you specify a process but do not specify a CPU, this command displays the statistics for the default CPU. If you do not specify a process or CPU, this command displays the historical statistics for all CPUs.

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.

Examples

# Display the historical CPU usage statistics.

Parameters

background: Saves operating information in the background. If you do not specify this keyword, the system displays or saves operating information in the CLI and you cannot execute other commands during the process. It is time consuming if a large amount of operating information is to be collected. If you specify this keyword, the system saves operating information in the background and users can execute other commands in the CLI during the process.

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.

verbose: Displays or saves detailed 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.

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

Before performing an active/standby switchover for MPUs or switching fabric modules, execute this command multiple times to identify whether the system is operating stably. If the value for the Redundancy Stable field is not Stable, you cannot perform a switchover.

The device/card 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/cards 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 system internal process state command in probe view to display service operating status.

Examples

# Display brief information about system stability and status.

Predefined user roles

network-admin

Usage guidelines

This command takes effect only when the hardware-failure-detection forwarding isolate command is executed.

When the hardware-failure-protection aggregation command is executed, the system uses the following rules when it detects a hardware failure on an aggregation group member interface:

· If the undo hardware-failure-protection auto-down command is executed on the member interface and the member interface is the only member in up state in the group, the system does not shut down the interface.

· If the undo hardware-failure-protection auto-down command is executed on the member interface and the member interface is not the only member in up state in the group, the system shuts down the interface.

· If the hardware-failure-protection auto-down command is executed on the member interface, the system shuts down the interface, whether or not the member interface is the only member in up state in the group.

This command does not take effect on a member interface in the following situations:

· Loopback testing is enabled (using the loopback { external | internal } command).

· The interface is forcibly brought up (using the port up-mode command).

· The undo hardware-failure-protection auto-down command is not executed on the interface.

Usage guidelines

To ensure service continuity, verify that the interface has a backup link before configuring this command.

After you enable hardware failure protection on an interface, the system automatically shuts down the interface when it detects a hardware failure on the interface. An interface shut down this way is in Protect Down state. After the failure on an interface is removed, bring the interface up by using the undo shutdown command.

This command takes effect only when the hardware-failure-detection forwarding isolate command is executed.

This command does not take effect on an interface in the following situations:

· Loopback testing is enabled (using the loopback { external | internal } command).

· The interface is forcibly brought up (using the port up-mode command).

Parameters

ratio: Specifies free-memory thresholds in percentage. If you do not specify this keyword, the command sets free-memory thresholds in MB.

minor minor-value: Specifies the minor alarm threshold. 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. 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. 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. This threshold must be equal to or less than the total memory size.

early-warning early-warning-value: Specifies the early-warning threshold. To view the value range for this threshold, enter a question mark (?) in the place of the early-warning-value argument. Setting this threshold to 0 disables the early warning feature.

secure secure-value: Specifies the sufficient-memory threshold. To view the value range for this threshold, enter a question mark (?) in the place of the secure-value argument.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command sets free-memory thresholds for the active MPU.

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

Usage guidelines

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.

For slots that support low memory, the system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information. If the LowMem field is displayed for a slot, the slot supports low memory.

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

Parameters

ratio ratio-value: Specifies the kernel memory fragment ratio alarm threshold in percentage, in the range of 1 to 100.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command sets the kernel memory fragment ratio alarm threshold for the active MPU.

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

Usage guidelines

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 command enables the device to monitor the kernel memory fragment ratio. If the kernel memory fragment ratio decreases to or below the alarm threshold, the kernel memory usage is low and an alarm notification is generated. If the kernel memory fragment ratio increases above the alarm threshold, the kernel memory usage returns to the normal state and a recovery notification is generated.

Usage guidelines

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.

reboot

Use reboot to reboot the device.

Syntax

reboot [ slot slot-number ] [ force ]

Views

User view

Predefined user roles

network-admin

Parameters

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

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 device does not have a standby MPU, rebooting the active MPU reboots the entire device. If the device has a standby MPU and the standby MPU is operating correctly, rebooting the active MPU triggers a switchover.

To ensure correct operation of the system and cards, do not trigger a switchover by rebooting the active MPU if the standby MPU is not in Stable state. To view the status of the standby MPU, execute the display system stable state command.

Examples

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

<Sysname> reboot

Start to check configuration with next startup configuration file, please wait.........DONE!

Current configuration will be lost after the reboot, save current configuration? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

Parameters

time: Specifies the reboot time in the hh:mm format. The value range for hh is 0 to 23. The value range for mm is 0 to 59.

date: Specifies the reboot date in the MM/DD/YYYY or YYYY/MM/DD format. The value range for YYYY is 2000 to 2035. The value range for MM is 1 to 12. The value range for DD varies by month.

Usage guidelines

CAUTION:

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

‌

When the date argument is not specified, the system uses the following rules to determine the reboot time:

· If the reboot time is later than the current time, a reboot occurs at the reboot time of the current day.

· If the reboot time is earlier than the current time, a reboot occurs at the reboot time the next day.

The device supports only one device reboot schedule. If you execute both the scheduler reboot delay and scheduler reboot at commands or execute one of the commands multiple times, the most recent configuration takes effect.

For data security, the system does not reboot at the reboot time if a file operation is being performed.

Parameters

schedule-name: Specifies the schedule name, a case-sensitive string of 1 to 47 characters.

Usage guidelines

You can configure a schedule to have the device automatically run a command or a set of commands without administrative interference.

To configure a schedule:

1. Use the scheduler job command to create a job and enter job view.

2. Use the command command to assign commands to the job.

3. Use the scheduler schedule command to create a schedule and enter schedule view.

4. Use the job command to assign the job to the schedule. You can assign multiple jobs to a schedule. The jobs must already exist.

5. Use the user-role command to assign user roles to the schedule. You can assign up to 64 user roles to a schedule.

6. Use the time at, time once, or time repeating command to specify an execution time for the schedule. You can specify only one execution time for a schedule.

Examples

# Create a schedule named saveconfig.

Use undo shutdown-interval to restore the default.

Syntax

shutdown-interval interval

undo shutdown-interval

Default

The port status detection timer setting is 30 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The value of 0 indicates that port status detection is not automatically performed, and you need to execute the undo shutdown command to restore the port status manually.

Usage guidelines

The device starts a port status detection timer when a port is shut down by a protocol. If the port has been in down state before the timer expires, the device will set the port status to the port's physical status.

If you change the timer setting during port detection, the device compares the new setting (T1) with the time that elapsed since the port was shut down (T).

· If T < T1, the port will be brought up after T1 – T seconds.

· If T ≥ T1, the port is brought up immediately.

For example, the timer setting is 30 seconds. If you change it to 10 seconds 2 seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer setting to 2 seconds 10 seconds after the port is shut down, the port comes up immediately.

Examples

# Set the port status detection timer to 100 seconds.

<Sysname> system-view

[Sysname] shutdown-interval 100
