1.1  Configuration File Management Commands

1.1.1  display current-configuration

Syntax

display current-configuration [ [ controller | interface [ interface-type [ interface-number ] ] | configuration [ configuration ] ] [ | { begin | exclude | include } text ] ] | [ vlan [ vlan-id ] ]

View

Any view

Parameters

controller: Views the configuration information of controllers.

interface: Views the configuration information of interfaces.

interface-type: Type of an interface, which may be Aux, Ethernet, GigabitEthernet, Loopback, NULL, Vlan-interface, or M-Ethernet.

interface-number: Number of an interface.

configuration configuration: Views the configuration information excluding the port information. The value of the configuration argument is the keyword of the configuration on the switch, such as:

l           acl-adv: Views the configuration information of advanced ACLs.

l           ospf: Views the configuration information of the OSPF protocol.

l           system: Views the name of the host.

l           timerange: Views the configuration information of the time range.

The optional configuration keywords are available only after the related functions are enabled on the switch.

vlan [ vlan-id ]: Views the VLAN configuration in the system. If the vlan-id argument is not specified, the configuration information of all VLANs in the system is displayed; if the vlan-id argument is specified, the configuration information of the specified VLAN is displayed.

|: Uses the regular expression to filter the configuration information to be output.

begin: Displays the configuration beginning with the specified characters.

exclude: Displays the configuration excluding the specified characters.

include: Displays the configuration including the specified characters.

text: Text included in a configuration item, expressed in a regular expression. .

Table 1-1 Description on the special characters in the regular expression

Character	Meaning	Description
_	Underline, which can represent the following characters: (^|$|[,{}]), space, starting character, and ending character.	If the first character of a regular expression is not “_”, the number of underline characters in a regular expression is only limited by the length of a command line. If the first character of a regular expression is “_”, there can be up to four other successive underline characters following it. If the underline characters are not successive, only the first underline character group is matched. The subsequent underline groups are ignored.
(	Left parenthesis, push-in-stack signal	You are not recommended to use this character in a regular expression.
.	Period, a wildcard which can represent any single character, including spaces.	—
*	Asterisk. It means that the preceding sub-expression can be matched for zero or multiple times.	zo* matches “z” and “zoo”.
+	Plus sign. It means that the preceding sub-expression can be matched for once or multiple times.	zo+ matches "zo" and “zoo”, but not "z".

 

Description

Use the display current-configuration command to display the currently running configuration parameters of the switch.

Running configuration parameters adopting the default values will not be displayed.

If you want to verify the configurations after finishing a set of configurations, you can use the display current-configuration command to display the running parameters. Although you have configured some parameters, they are not displayed if the related functions are not effective.

When there is plenty of configuration information, you can use a regular expression to filter the output information.

Related commands: save, reset saved-configuration, display saved-configuration.

1.1.4  display startup

Syntax

display startup

View

Any view

Parameters

None

Description

Use the display startup command to display the configuration file names used for the current and the next start-ups.

Related commands: startup saved-configuration.

Examples

# Display the configuration file names used for the current and the next start-ups.

<H3C> display startup

MainBoard:

  Startup saved-configuration file:          flash:/config.cfg

  Next startup saved-configuration file:     flash:/config.cfg

1.1.5  reset saved-configuration

Syntax

reset saved-configuration

View

User view

Parameters

None

Description

Use the reset saved-configuration command to remove configuration files from the Flash memory of the Ethernet switch.

Perform this command cautiously. You are recommended to consult technical support personnel first.

Generally, this command is used in the following situations:

l           After software upgrade, configuration files in Flash memory may not match the new software in version. Perform the reset saved-configuration command to remove the old configuration files.

l           If a used Ethernet switch is applied to the new circumstance and the original configuration files cannot meet the new requirements, the Ethernet switch must be configured again. Remove the original configuration files for reconfiguration.

If no configuration file exists in the Flash memory when an Ethernet switch is powered on and initialized, it will be initialized through the default configuration files.

Related commands: save, display current-configuration, display saved-configuration.

Examples

# Remove the configuration files from the Flash memory of the Ethernet switch.

<H3C> reset saved-configuration

The saved configuration will be erased.

Are you sure?[Y/N]y

Configuration in flash memory is being cleared.

Please wait ...

....

Configuration in flash memory is cleared.

1.1.6  save

Syntax

save [ file-name | safely ]

View

User view

Parameters

file-name: File name with the extension name .cfg, a character string of 5 to 56 characters.

safely: Saves the configuration files to the Flash memory in the safely mode.

Description

Use the save command to save the current configuration files to the Flash memory.

After finishing a group of configurations and achieving expected functions, you should remember to save the current configuration files in the Flash memory.

The configuration files can be saved in one of the following two ways:

l           Fast saving: in this mode, the configuration files are saved fast. However, if restart or power-off occurs in the saving procedure, the configuration files will be lost.

l           Safely saving: in this mode, the configuration files are saved slowly. However, even if restart or power-off occurs in the saving procedure, the configuration files still exist.

If the save command is executed without the safely keyword, the configuration files are saved in the fast saving mode. If the save command is executed with the safely keyword, the configuration files are saved in the safely saving mode.

You are recommended to adopt the fast saving mode in the conditions of stable power and adopt the safely saving mode in the conditions of unstable power or remote maintenance.

Related commands: reset saved-configuration, display current-configuration, display saved-configuration.

Examples

# Save the current configuration files to the Flash memory.

<H3C> save

The configuration will be written to the device.

Are you sure?[Y/N]y

Now saving current configuration to the device.

Saving configuration flash:/config.cfg. Please wait...

...........

Configuration is saved to flash memory successfully.

1.1.7  startup saved-configuration

Syntax

startup saved-configuration { cfgfile | device-name }

View

User view

Parameters

cfgfile: Name of a configuration file. It is a string of 1 to 64 characters.

device-name: Name of the current storage device.

Description

Use the startup saved-configuration command to configure the configuration file to be used in the next startup.

The configuration file uses .cfg as its extension name and is saved in the root directory of the Flash.

Related commands: display startup.

Examples

# Configure the configuration file to be used in the next startup as config.cfg.

<H3C> startup saved-configuration config.cfg
