Introducción
Este documento describe cómo restablecer los dispositivos de hardware de Cisco Secure Email Gateway (SEG) o Secure Web Appliance (SWA), si utiliza el método de autenticación enablediag.
Prerequisites
Componentes Utilizados
- SEG AsyncOS 14.2.2 o versiones posteriores
- SWA AsyncOS 14.5.1-08 o versiones posteriores
La información que contiene este documento se creó a partir de los dispositivos en un ambiente de laboratorio específico. Todos los dispositivos que se utilizan en este documento se pusieron en funcionamiento con una configuración verificada (predeterminada). Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.
Problema
No se puede acceder al SEG/SWA a través de la interfaz de usuario web o la red si se produce un error en una actualización o si los servicios se dañan, lo que deja a la RMA como única opción. La nueva función del SEG/SWA permite un restablecimiento completo del dispositivo a los parámetros de fábrica, lo que evita la necesidad de realizar una RMA del dispositivo.
Solución
SEG/SWA y la contraseña de administrador en la mano, acceda al dispositivo a través de la consola o de la sesión de terminal Ethernet.
Usuario: enable diag
password: la contraseña del administrador
Los comandos disponibles incluyen la nueva opción, resetappliance
La opción resetappliance genera una lista de opciones de versión anteriores que se deben seleccionar.
Una vez seleccionado, el dispositivo borra todos los parámetros predeterminados del sistema, incluida la eliminación de los parámetros de IP de red.
El resultado final produce un SEG/SWA limpio y sin configurar listo para la configuración.

This command will revert the appliance to a previous version of AsyncOS.
Warning: Reverting the appliance is extremely destructive.
The following data will be destroyed in the process and should be backed up:
- current system configuration file
- all log files
- all reporting data (including saved scheduled and archived reports)
- any custom end user notification pages
- current network settings
Reverting the device will cause a reboot to take place.
After rebooting, the appliance reinitializes itself and reboots
again to the desired version, with default system configuration.
