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.

A device power cycling operation restores the local system time to the default. You must execute this command again to set the local system time.

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.

Usage guidelines

This command is supported only on BRAS-VMs or FWD-VMs.

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.

Use display cpu-usage history to display the historical CPU usage statistics in a coordinate system.

Syntax

display cpu-usage history [ job job-id ]

Views

Any view

Predefined user roles

network-admin

network-operator

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.

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.

In an IRF 3.1 system, follow these guidelines:

· To display the historical CPU usage statistics for a process on a PEX, log in to the PEX, specify the process ID for the command, and execute the command.

· To display the historical CPU usage statistics for a PEX, use one of the following methods:

¡ Log in to the PEX and execute the command without specifying a process ID.

¡ (MDC-capable devices.) Log in to the MDC to which the PEX belongs and execute the command without specifying a process ID.

¡ (MDC-incapable devices.) Execute the command on the parent without specifying a process ID.

display diagnostic-information

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

Syntax

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

hardware: Specifies hardware-related diagnostic information.

infrastructure: Specifies diagnostic information for the fundamental features.

l2: Specifies diagnostic information for the Layer 2 features.

l3: Specifies diagnostic information for the Layer 3 features.

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

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

verbose: Saves detailed diagnostic 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.

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

Usage guidelines

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

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

· Use the display diagnostic-information command to collect diagnostic 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 diagnostic 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 diagnostic information.

# Display the diagnostic information for all features and modules.

<Sysname> display diagnostic-information

Usage guidelines

To ensure correct operation of the services that require DMA memory, the system monitors the amount of free DMA memory space regularly. If the amount of free DMA memory space decreases to or below the alarm threshold, the system generates a notification indicating that the DMA memory space is insufficient. If the amount of free DMA memory space increases above the normal state threshold, the system generates a notification indicating that the DMA memory space is sufficient.

Examples

# Set the DMA memory alarm threshold and the normal state threshold to 32KB and 96 KB, respectively.

Predefined user roles

network-admin

Parameters

interval: Specifies the CPU core usage statistics interval in seconds. The value range for this argument is 10 to 3600. As a best practice, set this argument to a multiple of the sampling interval, which is fixed at 5 seconds. If you do not do so, the effective statistics interval is the biggest multiple of the sampling interval that is smaller than the setting. For example, if you set this argument to 12 seconds, the effective statistics interval is 10 seconds.

slot slot-number: Specifies a card by its slot number.

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

core-id-list: Specifies a space-separated list of up to 10 CPU core items. Each item specifies a CPU core or a range of CPU cores in the form of core-id1 [ to core-id2 ]. The value for core-id2 must be equal to or greater than the value for core-id1.

Usage guidelines

The device samples CPU core usage at 5-second intervals and calculates the average value during each CPU core usage statistics interval. If the value during an interval is greater than a CPU core usage alarm threshold, the device issues an alarm and logs the event.

Examples

# Set the usage statistics interval to 60 seconds for a CPU core.

Parameters

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

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.

Examples

# Set the kernel memory fragment ratio alarm threshold to 80.

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.

Examples

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

<Sysname> reboot

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

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

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.

Parameters

role-name: Specifies a user role name, a case-sensitive string of 1 to 63 characters. The user role can be user-defined or predefined. Predefined user roles include network-admin, network-operator, and level-0 to level-15.

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.

Examples

# Assign the rolename user role to the test schedule.

<sysname> system-view

[Sysname] scheduler schedule test

[Sysname-schedule-test] user-role rolename

# Assign the security-audit user role to the test schedule.

<sysname> system-view

[Sysname] scheduler schedule test

[Sysname-schedule-test]user-role security-audit

This operation will delete all other user roles for the schedule. Are you sure? [Y/N]:y

# Change the user role assigned to the test schedule from security-audit to network-admin.
