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

mdc-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

CAUTION

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.

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 mdc mdc-id }

undo clock protocol

Default

The device obtains the UTC time from an NTP time source specified on the default MDC.

Views

Predefined user roles

network-admin

mdc-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.

mdc mdc-id: Specifies the MDC to be used for time synchronization. The value range for the mdc-id argument is 1 to 16 for the S12500X-AF and S12500-X switch series, and 1 to 9 for the S9800 switch series.

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.

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.

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

clock summer-time name start-time start-date end-time end-date add-time

¡     day—Takes Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.

add-time: Specifies the time to be added to the standard 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.

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.

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.

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.

Examples

# (In standalone mode.) Display the historical CPU usage statistics.

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 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 extension. 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 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 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.

To execute the display diagnostic-information command, make sure the CPU usage is less than 100% and the memory usage is equal to or less than 90%. To view the CPU usage and the memory usage, use the display cpu-usage and display memory commands.

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. The value range for the mdc-id argument is 1 to 16 for the S12500X-AF and S12500-X switch series, and 1 to 9 for the S9800 switch series.

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/card/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/cards/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.

Parameters

handshake-timeout: Shuts down all service ports when the connection between the MPU and service modules times out.

fab-absent: Shuts down all service ports when no fabric modules are detected.

Usage guidelines

This command is typcially used in active/standby dual host scenarios (such as VRRP). After the monitor disable-port command is executed, the system will shut down all service ports on the active device when the connection between the MPU and the service modules on the active device times out, or no fabric modules are detected. As a consequence, all services will be switched to the standby device rapidly.

Views

User view

Predefined user roles

network-admin

mdc-admin

Parameters

chassis chassis-number: Specifies an IRF member device by its member ID. If you do not specify an IRF member device, the command reboots all IRF member devices. (In IRF mode.)

slot slot-number: Specifies a card by its slot number. If you do not specify a card, the command reboots the IRF member device.(In standalone mode.) (In IRF mode.)

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

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.

In standalone mode:

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.

In IRF mode:

If the IRF fabric has only one MPU, rebooting the MPU reboots the entire IRF fabric. If the IRF fabric 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 IRF fabric 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

# (In standalone mode.) 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

Views

System view

Predefined user roles

network-admin

mdc-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

[Sysname] shutdown-interval 100

switch-fabric isolate

Use switch-fabric isolate to isolate a switching fabric module or channel from the data plane.

Use undo switch-fabric isolate to cancel the isolation of a switching fabric module or channel.

Syntax

In standalone mode:

switch-fabric isolate slot slot-number [ channel channel-number ]

undo switch-fabric isolate slot slot-number [ channel channel-number ]

In IRF mode:

switch-fabric isolate chassis chassis-number slot slot-number [ channel channel-number ]

undo switch-fabric isolate chassis chassis-number slot slot-number [ channel channel-number ]

Default

A switching fabric module is not isolated from the data plane and can forward traffic.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

slot slot-number: Specifies a switching fabric module by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a switching fabric module on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the module.(In IRF mode.)

channel channel-number: Specifies a data channel by its number. If you do not specify this option, the command isolates the entire switching fabric module.

Usage guidelines

CAUTION

CAUTION:

·     Do not isolate the only switching fabric module of the device.

·     Use this command only if required. If the device has multiple switching fabric modules, isolating a switching fabric module or channel decreases the forwarding bandwidth and reduces the forwarding performance.

 

This command is supported in Release 2712 and later.

An isolated switching fabric module continues to communicate with the MPU, and can forward traffic immediately after the isolation is canceled. The isolation does not affect protocol packet parsing and protocol calculation on the control plane.

You can use this command to identify whether switching fabric modules can forward traffic correctly.

To reduce impact on forwarding performance, you can isolate only the channels with errors instead of isolating the entire switching fabric module.

To use an isolated switching fabric module or channel, use the undo switch-fabric isolate command to cancel the isolation.

Examples

# (In standalone mode.) Isolate the switching fabric module in slot 10.

<Sysname> system-view

[Sysname] switch-fabric isolate slot 10

The command will isolate the switch fabric from the system. Continue? [Y/N]y

switch-fabric removal-signal-suppression

CAUTION

CAUTION:

This command is supported only in R2719 and later.

 

Syntax

switch-fabric removal-signal-suppression

undo switch-fabric removal-signal-suppression

Default

Removal interrupt signals from switching fabric modules are not suppressed.

Views

System view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

CAUTION

CAUTION:

Use this command with caution. This command might result in packet loss and service outage.

Typically, removing a switching fabric module triggers one removal interrupt signal. Upon receiving the signal, the system switches traffic on the switching fabric module to other switching fabric modules to ensure service continuity. Upon hardware failure or signal interference, however, removal interrupt signals might be frequently triggered. To prevent the interrupt signals from affecting system operation, you can execute this command to suppress the interrupt signals.

Examples

# Suppress removal interrupt signals from switching fabric modules.

<Sysname> system-view

[Sysname] switch-fabric removal-signal-suppression

switch-linecard isolate

Parameters

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

chassis chassis-number: Specifies an IRF member device by its member ID. (In IRF mode.)

Usage guidelines

This command is supported in Release 2712 and later.

To decrease the impact of service card failures on device performance, use this command to isolate failed service card before troubleshooting the issue. An isolated service card does not forward packets.

Rebooting an isolated service card cancels the isolation. To isolate the service card again after the reboot, execute this command again.

To view the operating status of service cards, execute the display device command. The status field for an isolated service card displays Offline.

Examples

# (In standalone mode.) Isolate the service card in slot 2.
