Example: Deleting a Logical System

This example shows how to delete a logical system configured for an SRX Series Services Gateway device running logical systems. Only the primary administrator can delete a logical system.


The example uses an SRX5600 device running Junos OS with Logical Systems.

Alternatively, follow those instructions substituting your own configuration values.


This example shows how to delete a logical system, which you can do at any time. However, if you have configured the device to include the maximum number of logical systems that are supported you must first delete an existing logical system before you can add another one.

Deletion of a logical system is a simple procedure that includes these tasks:

  • Remove from the logical system the security profile that is bound to it.

    Note that in this step you are not deleting the security profile–it might be used for other logical systems–but simply detaching it from the logical system that you intend to delete.

  • Detach from the logical system any login classes that are associated with it.

    Removing them from the logical system does not delete the login classes.

  • Delete the logical system.




CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the Junos OS CLI User Guide.

To delete a logical system:

  1. Determine that the logical system that you want to delete exists.

  2. Delete the security profile.

    Step-by-Step Procedure

    1. Verify that security profile that you intend to detach from the logical system is bound to it.

    2. Detach the security profile from the logical system.

  3. Delete the login classes.

    Step-by-Step Procedure

    1. Display the login class and login user configurations for the user logical system administrator.

    2. Detach the login class for the administrator from the logical system.

    3. Display the login class and login user configurations for the user.

    4. Detach the login class for the user from the logical system.

  4. Delete the logical system.


From configuration mode, confirm your configuration by entering the show logical-systems command. In this case, the logical system that you deleted should not be included in displayed list of logical systems configured for the device. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

If you are done configuring the device, enter commit from configuration mode.


To confirm that the configuration is working properly, perform these tasks:

Verifying That the Correct Logical System and Its Profile and Attached Class Were Deleted


Verify if the logical system has been deleted using the show command described previously.
