Introduction

This document describes how to reset the Cisco Secure Email Gateway (SEG) or Secure Web Appliance (SWA) hardware appliances, if you use the enablediag authentication method.

Prerequisites

Components Used

- SEG AsyncOS 14.2.2 or later versions

- SWA AsyncOS 14.5.1-008 or later versions

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any comman

Problem

The SEG/SWA is inaccessible through WebUI or network if an upgrade fails or services get corrupted, this leaves a RMA as the only option. The new capability in the SEG/SWA allows a full reset of the appliance to the factory settings and this avoids the need to RMA the appliance.

Solution

SEG/SWA and admin password in hand, access the appliance via console or ethernet terminal session.

User username: enablediag

password: the admin password

The available commands include the new option, resetappliance

The resetappliance option produces a list of previous version options to select.

Once selected the appliance clears all settings to system default including the removal of network ip settings.

The final result produces a clean unconfigured SEG/SWA ready for setup.

Complete sample output from the resetappliance process.
