Juniper EX Series User Manual

Loading a Previous Configuration File with the J-Web Interface
To load (roll back) and commit a previous configuration file stored on the switching
platform:
1. Select Config Management > History. A list of current and previous 49 configurations
is displayed as Configuration History in the main pane.
2. In the Action column, click Rollback for the version of the configuration you want to
load.
The main pane displays the results of the rollback operation.
NOTE: When you click Rollback, the switch loads and commits the selected
configuration. This behavior is different from the switch's behavior that
occurs after you enter the rollback configuration mode command from
the CLI. In the latter case, the configuration is loaded but not committed.

Setting or Deleting the Rescue Configuration (J-Web Procedure)
NOTE: This topic applies only to the J-Web Application package.
A rescue configuration is a well-known configuration that recovers a switch from a
configuration that denies management access. You set a current committed configuration
to be the rescue configuration through the J-Web interface or CLI.
If someone inadvertently commits a configuration that denies management access to
an EX Series switch and the console port is not accessible, you can overwrite the invalid
configuration and replace it with the rescue configuration by using the LCD panel on the
switch. The rescue configuration is a previously committed, valid configuration. We
recommend that the rescue configuration include the IP address (accessible from the
network) for the management port.
To view, set, or delete the rescue configuration using the J-Web interface, select Maintain
> Config Management > Rescue. On the Rescue page, you can perform the following
tasks:
•
View the current rescue configuration—Click View rescue configuration.
•
Set the current running configuration as the rescue configuration—Click Set rescue
configuration.
