clear configure

To clear the running configuration, use the clear configure command in global configuration mode.

clear configure {primary | secondary | all | command}

Syntax Description

command	Clears the configuration for a specified command. For more information, see individual entries in this guide for each clear configure command command.
primary	Clears commands related to connectivity, including the following commands: •tftp-server •shun •route •ip address •mtu •failover •monitor-interface •boot
secondary	Clears commands not related to connectivity (that are cleared using the primary keyword).
all	Clears the entire running configuration.

Defaults

No default behavior or values.

Command Modes

The following table shows the modes in which you can enter the command:

Command Mode	Firewall Mode		Security Context
	Routed	Transparent	Single	Multiple
				Context	System
Global configuration	•	•	•	•	•

Command History

Release	Modification
1.1(1)	This command was introduced.
3.1(1)	This command was modified to allow you to clear the configuration for each commmand.

Usage Guidelines

When you enter this command in a security context, you clear only the context configuration. If you enter this command in the system execution space, you clear the system running configuration as well as all context running configurations. Because you cleared all context entries in the system configuration (see the context command), the contexts are no longer running, and you cannot change to a context execution space.

Before clearing the configuration, make sure you save any changes to the boot config command (which specifies the startup configuration location) to the startup configuration; if you changed the startup configuration location only in the running configuration, then when you restart, the configuration loads from the default location.

Examples

The following example clears the entire running configuration:

hostname(config)# clear configure all

Related Commands

Command	Description
configure http	Merges a configuration file from the specified HTTP(S) URL with the running configuration.
configure memory	Merges the startup configuration with the running configuration.
configure net	Merges a configuration file from the specified TFTP URL with the running configuration.
show running-config	Shows the running configuration.
