Cisco Cisco ASA 5550 Adaptive Security Appliance Guía Para Resolver Problemas

This process is defined under the ASDM configuration on the ASA. A sample configuration definition of the
current image that is used looks like this:

asdm image disk0:/asdm−702.bin

In order to further verify, you can also use the show asdm image command:

ciscoasa# show asdm image

Device Manager image file, disk0:/asdm−702.bin

This step is essential in the ASDM configuration, because it defines which networks have access to the ASA.
A sample configuration looks like this:

http server enable

http 192.168.1.0 255.255.255.0 inside

http 64.0.0.0 255.0.0.0 outside

Verify that you have the necessary networks defined in the previous configuration. The absence of those
definitions causes the ASDM launcher to time out while it connects and gives this error:

The ASDM launch page (https://<ASA IP address>/admin) causes the request to time out and no page is
displayed.

Further verify that the HTTP server uses a non−standard port for ASDM connection, such as 8443. This is
highlighted in the configuration:

ciscoasa(config)# show run http

http server enable 8443

If it uses a non−standard port, you need to specify the port when you connect to the ASA in the ASDM
launcher as:
