Acceso al ASDM

Despues habrimos un navegador web para acceder al ASDM por primera vez. En la siguiente imagen se muestra accesando al ASDM.


La pagina nos muestra tres opciones.

Install ASDM Launcher and Run ASDM: El launcher y ASDM se ejecutaran como aplicaciones nativas desde la PC sin necesidad de un navegador web.

Run ASDM: Ejecutara ASDM desde el navegador web como una aplicación Java.

Run Startup Wizard: ASDM iniciará un asistente que nos guiará a través de la configuracion inicial de ASA,
si aún no se ha hecho.

La primera opcion es la mas comun y se debe realizar solo una vez. Ya que tengamos instalado Cisco ASDM-IDM Launcher en nuestra PC ya podremos ejecutar la aplicacion directamente para iniciar una sesion ASDM. La primera opción es la opción más común y se debe hacer sólo una vez. Después de la aplicación Launcher está instalado, puede ejecutarlo directamente para iniciar una sesión de ASDM.

Para iniciar una sesion ejecutamos esta aplicacion el cual nos pedirá la direccion IP, nombre de usuario y contraseña. La dirección IP será almacenada en memoria caché para que la proxima vez que queramos iniciar sesion podamos elegirla de nuevo.


Una vez que lanzamos esta aplicación se conecta al ASA correctamente y con esto ya tenemos ASDM listo para trabajar.
