load

Syntax

QFX Series

Release Information

Command introduced before Junos OS Release 7.4.

Command introduced in Junos OS Release 11.1 for the QFX Series.

Description

Load a configuration from an ASCII configuration file, from terminal input, or from the factory default. Your current location in the configuration hierarchy is ignored when the load operation occurs.

Options

dhcp-snooping—(QFX Series switches) Loads DHCP snooping entries.

factory-default—Loads the factory configuration. The factory configuration contains the manufacturer’s suggested configuration settings. The factory configuration is the router or switch’s first configuration and is loaded when the router or switch is first installed and powered on.

On J Series Services Routers, pressing and holding down the Config button on the router for 15 seconds causes the factory configuration to be loaded and committed. However, this operation deletes all other configurations on the router; using the load factory-default command does not.

filename—Name of the file to load. For information about specifying the filename, see Viewing Files and Directories on a Device Running Junos OS.

merge—Combine the configuration that is currently shown in the CLI with the configuration.

override—Discard the entire configuration that is currently shown in the CLI and load the entire configuration. Marks every object as changed.

patch—Change part of the configuration and mark only those parts as changed.

replace—Look for a replace tag in filename, delete the existing statement of the same name, and replace it with the configuration.

set—Merge a set of commands with an existing configuration. This option executes the configuration instructions line by line as they are stored in a file or from a terminal. The instructions can contain any configuration mode command, such as set, edit, exit, and top.

relative—(Optional) Use the merge or replace option without specifying the full hierarchy level.

terminal—Use the text you type at the terminal as input to the configuration. Type Ctrl+d to end terminal input.

update—Discard the entire configuration that is currently shown in the CLI, and load the entire configuration. Marks changed objects only.

Note: If you are using Junos OS in a Common Criteria environment, system log messages are created whenever a secret attribute is changed (for example, password changes or changes to the RADIUS shared secret). These changes are logged during the following configuration load operations: load merge load replace load override load update For more information, see the Secure Configuration Guide for Common Criteria and Junos-FIPS .

Required Privilege Level

configure—To enter configuration mode, but other required privilege levels depend on where the statement is located in the configuration hierarchy.
