load
Syntax
load (factory-default | merge | override | patch | replace | set | update) (filename | terminal)
<json>
<relative>
QFX Series
load (dhcp-snooping filename)
VMX Series
load (<dhcp-security-snoop | dhcpv6-security-snoop>filename)
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.
For information on valid filename and URL formats, see Format for Specifying Filenames and URLs in Junos OS CLI Commands.
load can be run from configuration mode only.
Options
dhcp-snooping—(QFX Series
switches) Loads DHCP snooping entries.
dhcp-security-snoop—(VMX Series
switches) Loads DHCP snooping entries.
dhcpv6-security-snoop—(VMX
Series switches) Loads DHCPv6 snooping
entries.
factory-default—Loads the
factory configuration. The factory configuration
contains the manufacturer’s suggested
configuration settings. The factory configuration
is the first configuration for the router or
switch and is loaded when the router or switch is
first installed and powered on. The
factory-default option cannot be
combined with other options.
To load the factory default configuration, you must first unprotect any protected hierarchies in the configuration.
filename—Name
of the file to load. For information about
specifying the filename, see Viewing Files and Directories on a Juniper
Networks Device.
json—(Optional) Load
configuration data that uses JavaScript Object
Notation (JSON) format. This option can be used
with the merge,
override, or
update options.
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.
relative—(Optional) Load the new
configuration data relative to the current edit
point in the configuration hierarchy.
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.
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.
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
The load commands for
dhcp-security-snoop and
dhcpv6-security-snoop are
restricted to admin only.
configure—To enter configuration mode, but other required privilege levels depend on where the statement is located in the configuration hierarchy.
Sample Output
The following is an example of a load scenario using Secure Copy (scp).
To Load a Configuration File Using Secure Copy Protocol (scp) with ’source-address’ and ’routing-instance’ options
To load a configuration file using the scp command with the source-address and routing-instance options, enter
the following command:
root@host# load merge scp://user@hostname/path/filename source-address address routing-instance instance-name
The scp options source-address and routing-instance are supported for load override, load patch, load replace, load set, and load update options also.
