Cisco Cisco ASA 5525-X Adaptive Security Appliance - No Payload Encryption Guía De Instalación

(CLI) Use the show version command to verify the software version of your ASA. (ASDM) The software 
version appears on the ASDM home page; view the home page to verify the software version of your ASA.

This section describes how to install the ASDM and operating system (OS) images.

This procedure uses TFTP. For FTP or HTTP, see the copy command.

If you have a Cisco.com login, you can obtain the OS and ASDM images from the following website:

Back up your configuration file. To print the configuration to the terminal, enter the following command:

hostname# show running-config

Copy the output from this command, then paste the configuration in to a text file.

If you are upgrading from a pre-8.3 version, then the running configuration is backed up 
automatically.

For other methods of backing up, see the “Managing Software and Configurations” chapter in Cisco ASA 
5500 Series Configuration Guide using the CLI.

Install the new images using TFTP. Enter this command separately for the OS image and the ASDM 
image:

hostname# copy tftp://server[/path]/filename {disk0:/ | disk1:/}[path/]filename

For example:

hostname# copy tftp://10.1.1.1/asa830-4-k8.bin disk0:/asa831-k8.bin

...

hostname# copy tftp://10.1.1.1/asdm-63096.bin disk0:/asdm-631.bin

If your ASA does not have enough memory to hold two images, overwrite the old image with the new 
one by specifying the same destination filename as the existing image.

To change the OS boot image to the new image name, enter the following commands:

hostname(config)# clear configure boot

hostname(config)# boot system {disk0:/ | disk1:/}[path/]new_filename

For example:

hostname(config)# clear configure boot
