Using the CLI to Choose a Customized Web Authentication Login Page from an External Web Server

Step 1 To specify the web authentication type, enter this command:

config custom-web webauth_type external.

command:

config custom-web ext-webauth-url url

You can enter up to 252 characters for the URL.

Step 3 To specify the IP address of your web server, enter this command:

config custom-web ext-webserver {add | delete} server_IP_address

Step 4 Enter save config to save your settings.

Step 5 Follow the instructions in the “Using the CLI to Verify the Web Authentication Login Page Settings”

section on page 10-20 to verify your settings.

Downloading a Customized Web Authentication Login Page

You can compress the page and image files used for displaying a web authentication login page into a

.tar file for download to a controller. These files are known as the webauth bundle. The maximum

allowed size of the files in their uncompressed state is 1 MB. When the .tar file is downloaded from a

local TFTP server, it enters the controller’s file system as an untarred file.

Note If you load a webauth bundle with a .tar compression application that is not GNU compliant, the

controller cannot extract the files in the bundle and the following error messages appear: “Extracting

error” and “TFTP transfer failed.” Therefore, Cisco recommends that you use an application that

complies with GNU standards, such as PicoZip, to compress the .tar file for the webauth bundle.
