Rolling Back Software

Occasionally you may want or need to revert to a previously running version of 128T software. This is referred to as rolling back, and can be accomplished via either the standalone 128T installer application, or by using Automated Provisioner. (Note: as with upgrading, rolling back software using Automated Provisioner is only possible on routers managed by a 128T Conductor.)

Rolling Back using the Interactive Installer

  1. As a Linux superuser (or as a Linux user with sudoers capability) run the Interactive Installer by issuing the command

    install128t
  2. Skip the step regarding the installation of a certificate by selecting No at the prompt.

  3. The Interactive Installer will determine that 128T software is already installed. In the dialog box, navigate to the item labeled Roll Back and press the space bar to select the item.

    tip

    The version of software that will be running after executing the roll back function is displayed in the footer of the window.

  4. Navigate to the OK button and press enter to select it.

  5. Follow the on-screen prompts to complete the Roll Back operation.

Rolling Back using Automated Provisioner

From the PCLI command line on your 128T conductor, issue the command:

send command rollback router [router name]

Confirming the action will initiate the rollback process.

Uninstalling 128T

To uninstall 128T software and remove all configuration, libraries, and applications installed along with 128T, use the command erase128t from the Linux shell, as root user.
