Device management commands

clock datetime

Use clock datetime to set the system time.

Syntax

clock datetime time date

Default

The system time is UTC time 00:00:00 01/01/2011.

Views

User view

Predefined user roles

network-admin

Parameters

time: Specifies a time in the hh:mm:ss format. The value range for hh is 0 to 23. The value range for mm is 0 to 59. The value range for ss is 0 to 59. The leading zero in a segment can be omitted. If the seconds segment is 0 (hh:mm:00), you can omit it. If both the minutes and seconds segments are 0 (hh:00:00), you can omit both of the segments. For example, to specify 08:00:00, you can enter 8.

date: Specifies a 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

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.

Examples

# Set the system time to 08:08:08 01/01/2015.

<Sysname> clock datetime 8:8:8 1/1/2015

# Set the system time to 08:10:00 01/01/2015.

<Sysname> clock datetime 8:10 2015/1/1

clock protocol

Use clock protocol to specify the system time source.

Use undo clock protocol to restore the default.

Syntax

clock protocol { none | ntp }

undo clock protocol

Default

The device obtains the UTC time from an NTP time source.

Views

System view

Predefined user roles

network-admin

Parameters

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

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

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 command, the device obtains the UTC time through NTP and calculates the system time. The device then periodically synchronizes the UTC time and recalculates the system time.

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

Examples

# Configure the device to use the local UTC time.

<Sysname> system-view

[Sysname] clock protocol none

clock summer-time

Use clock summer-time to set the daylight saving time.

Use undo clock summer-time to restore the default.

Syntax

The leading zero in a segment can be omitted. If the seconds segment is 0 (hh:mm:00), you can omit it. If both the minutes and seconds segments are 0 (hh:00:00), you can omit both of the segments. For example, to specify 08:00:00, you can enter 8.

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.

After you set the daylight saving time, the device recalculates the system time. To view the system time, use the display clock command.

Make sure all devices on the network are using the same daylight saving time as the local time.

Predefined user roles

network-admin

Parameters

id: Specifies an ID for the command, in the range of 0 to 4294967295. A command ID uniquely identifies a command in a job. Commands in a job are executed in ascending order of their command IDs.

command: Specifies the command to be assigned to the job.

Usage guidelines

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.

If you specify the ID of an existing command for another command, the existing command is replaced.

Make sure all commands in a schedule are compliant to the command syntax. The system does not examine the syntax when you assign a command to a job.

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 job cannot contain the telnet, ftp, ssh2, or monitor process command.

Examples

# Assign commands to the backupconfig job to back up the startup.cfg file to the TFTP server at 192.168.100.11.

Parameters

job job-id: Specifies a process by its ID. The value range for job-id is 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 an IRF member device by its member ID. If you specify a process but do not specify a member device, this command displays the statistics for the process on the master device. If you do not specify any options, this command displays the statistics for all processes on all member devices.

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.

Views

Any view

Predefined user roles

network-admin

network-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 for 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, this command automatically compresses the information before saving the 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 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 (>), pipeline signs (|), and quotation marks ("). For example, device name A/B will change to A_B in the file name, as in flash:/diag_A_B_20160101-000438.tar.gz.

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

This command does not support the |, >, and >> options.

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

Examples

# Display the operating information for all features and modules.

<Sysname> display diagnostic-information

Predefined user roles

network-admin

Parameters

slot slot-number: Specifies an IRF member device by its member ID.

subslot subslot-number: Specifies a subcard by its subslot number. This option is available only on S6800-2C, S6800-2C-FC, and S6800-4C switches.

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

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.

To reboot all member devices, do not specify the slot number option.

To reboot an IRF member device, specify the slot number and do not specify a subslot number.

To reboot the master, perform the following tasks:

Identify whether the IRF fabric has subordinate members and whether the subordinate members are operating correctly.

Use the display system stable state command to display system stability and status information.

If the IRF fabric has only one member device, the IRF fabric will be rebooted. If the IRF fabric has a subordinate member and the member is operating correctly, a switchover will occur.

 

IMPORTANT

IMPORTANT:

To ensure correct operation of the IRF fabric and member devices, do not trigger a switchover by rebooting the master if the status of a member device is not Stable.

 

Examples

# Reboot the device. Choose to save the running configuration when prompted.

<Sysname> reboot

CAUTION

CAUTION:

Device reboot interrupts network services.

 

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.

Examples

# Configure the device to reboot at 12:00 p.m. This example assumes that the current time is 11:43 a.m. on June 6, 2015.

shutdown-interval

Use shutdown-interval to set the port status detection timer.

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. To disable port status detection, set this argument to 0.

Usage guidelines

The device starts a port status detection timer when a port is shut down by a protocol. Once the timer expires, the device brings up the port so the port status reflects 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
