File Attribute Configuration Commands

display current-configuration

Syntax

display current-configuration [ configuration [ configuration-type ] | interface [ interface-type ] [ interface-number ] ] [ by-linenum ] [ | { begin | include | exclude } regular-expression ]

View

Any view

Parameters

configuration configuration-type: Specifies to display non-interface configuration. If configuration-type is not specified, all the non-interface configurations are displayed; if configuration-type is specified, the specified type of configuration is displayed. The configuration type you can specify is based on your current configuration. For example:

l          acl-adv: Indicates the advanced access control list (ACL) configuration.

l          acl-basic: Indicates the basic ACL configuration.

l          acl-ethernetframe: Indicates the Layer 2 ACL configuration.

l          hwping: Indicates the HWPing configuration.

l          isp: Indicates the internet service provider configuration.

l          radius-template: Indicates the radius template configuration.

l          system: Indicates the system configuration.

l          user-interface: Indicates the user interface configuration.

interface: Displays port/interface configuration.

interface-type: Port/interface type, which can be one of the following: Aux, GigabitEthernet, Loopback, NULL and VLAN-interface.

interface-number: Port/interface number.

by-linenum: Displays configuration information with line numbers.

|: Uses a regular expression to filter the configuration of the device to be displayed.

begin: Displays the configuration starting with the string specified by the regular-expression argument.

include: Displays the configuration including the string specified by the regular-expression argument.

exclude: Displays the configuration not including the string specified by the regular-expression argument.

regular-expression: A regular expression. Refer to Table 1-1 for details.

Table 1-1 Special characters in regular expression

Character	Meaning	Note
^	Starting sign, the regular expression matches lines starting with the specified string.	Regular expression “^user” matches a line begins with “user”, not “Auser”.
$	Ending sign, the regular expression matches lines ending with the specified string.	Regular expression "user$” matches a line ends with “user”, not “userA”.
.	Full stop, a wildcard used in place of any character, including blank	None
*	Asterisk, the character to the left of the asterisk in the expression should match zero or more consecutive times.	zo* can match “z” and “zoo”, and so on, but not “zo”.
+	Plus sign, the character to the left of the plus sign in the expression should match one or more consecutive times.	zo+ can match “zo” and “zoo”, and so on, but not “z”.
-	Hyphen. It connects two values (the smaller one before it and the bigger one after it) to indicate a range together with [ ].	For example, “1-9” means numbers from 1 to 9 (inclusive); “a-h” means from a to h (inclusive).
[ ]	Square brackets. Selects one character from the group.	For example, [1-36A] can match only one character among 1, 2, 3, 6, and A.
( )	Parenthesis. Specifies a group of characters. It is usually used with “+” or “*”.	For example, (123A) means a string “123A”; “408(12)+” can match 40812 or 408121212. But it cannot match 408. That is, “12” can appear continuously and it must at least appear once.

 

Description

Use the display current-configuration command to display the current configuration of the device.

After you finish a set of configurations, you can execute the display current-configuration command to display the parameters that take effect currently.

Note that:

l          Parameters that are the same as the default are not displayed.

l          The configured parameter whose corresponding function does not take effect is not displayed.

reset saved-configuration

Syntax

reset saved-configuration [ backup | main ]

View

User view

Parameters

backup: Erases the backup configuration file.

main: Erases the main configuration file.

Description

Use the reset saved-configuration command to erase the configuration file saved in the storage device.

The following two situations exist:

l          While the reset saved-configuration [ main ] command erases the configuration file with main attribute, it only erases the main attribute of a configuration file having both main and backup attribute.

l          While the reset saved-configuration backup command erases the configuration file with backup attribute, it only erases the backup attribute of a configuration file having both main and backup attribute.

You may need to erase the configuration file for one of these reasons:

l          After you upgrade software, the old configuration file does not match the new software.

l          The startup configuration file is corrupted or not the one you need.

 

 

Related commands: save.

Examples

# Erase the main configuration file to be used in the next startup.

<device> reset saved-configuration main

The saved configuration will be erased.

Are you sure?[Y/N]y

Configuration in flash memory is being cleared.

Please wait ...

....

 Unit1 reset saved-configuration successfully.

save

Syntax

save [ cfgfile | [ safely ] [ backup | main ] ]

View

Any view

Parameters

cfgfile: Path name or file name of a configuration file in the flash, a string of 5 to 56 characters.

safely: Saves the current configuration in the safe mode.

backup: Saves the configuration to the backup configuration file.

main: Saves the configuration to the main configuration file.

Description

Use the save command to save the current configuration to a configuration file in the flash.

When you use this command to save the configuration file,

l          If the main and backup keywords are not specified, the current configuration will be saved to the main configuration file.

l          If the cfgfile argument is specified, but the file specified by it does not exist, the system will create the file and then save the current configuration to it. The file attribute is neither main nor backup.

l          If the cfgfile argument is specified and the file specified by it exists, the system will save the current configuration to the specified file. The file attribute is the original attribute of the file.

l          If the cfgfile argument is not specified, the system will save the current configuration to the configuration file used for this startup. If the device starts up without loading the configuration file, the system will save the current configuration with the default name (config.cfg) in the root directory.

The system supports two modes for saving the current configuration file.

l          Fast saving mode. This is the mode when you use the save command without the safely keyword. The mode saves the file quicker but is likely to lose the original configuration file if the device reboots or the power fails during the process.

l          Safe mode. This is the mode when you use the save command with the safely keyword. The mode saves the file slower but can retain the original configuration file in the flash even if the device reboots or the power fails during the process.

 

 

 

Examples

# Save the current configuration to 123.cfg as the main configuration file for the next startup.

<device> save main

The configuration will be written to the device.

Are you sure?[Y/N]y

Please input the file name(*.cfg)(To leave the existing filename

 unchanged press the enter key):123.cfg

 

Now saving current configuration to the device.

Saving configuration. Please wait...

............

 Unit1 save configuration flash:/123.cfg successfully

startup saved-configuration

Syntax

startup saved-configuration cfgfile [ backup | main ]

undo startup saved-configuration [ unit unit-id ]

View

User view

Parameters

cfgfile: Path name or file name of a configuration file in the Flash, a string of 5 to 56 characters.

backup: Specifies the configuration file to be the backup configuration file.

main: Specifies the configuration file to be the main configuration file.

unit unit-id: Specifies the unit ID of a device. It only can be 1.

Description

Use the startup saved-configuration command to specify a configuration file to be the main configuration file or the backup configuration file.

Use the undo startup saved-configuration command to specify the device to start without loading the configuration file.

If you execute the startup saved-configuration command with neither the backup nor the main keyword specified, the configuration file identified by the cfgfile argument is specified as the main configuration file.

 

 

Related commands: display startup.

Examples

# Configure the configuration file named config.cfg as the main configuration file of the device.

<device> startup saved-configuration config.cfg main

 Please wait......Done!
