Question


How do I customize the End User Notification pages on the Cisco Web Security Appliance (WSA)?

Customized End User Notification (EUN) or block pages are available on AsyncOS builds 5.5.1 and later. Administrators can upload their respective customized EUN pages via FTP to directories under configuration -> eun. Initially the sub-directories under configuration > eun will contain all the standard EUN pages in their respective language directories like configuration/eun/{language}. Administrators can upload their customized EUN pages via FTP and override the standard EUN pages.

Set up customized EUN pages for the first time:

  • Upload all customized EUN pages via FTP to the respective folder
  • Configure WSA to use custom EUN pages from CLI using the command: advancedproxyconfig > EUN > Choose "Use Custom EUN pages"
  • Commit the changes using the CLI command - commit



Steps to upload EUN page:

For example, here are the required steps for changing DNS failure page on WSA in English:

  1. FTP to the WSA's Managment interface - ftp admin@<WSA_host_name_or_IP>
  2. Browse to directory: configuration > eun > en.
  3. Download and edit the ERR_DNS_FAIL page or create a new ERR_DNS_FAIL page. 
  4. Upload the edited ERR_DNS_FAIL page to the configuration > eun > en folder.


After uploading, log in to the CLI interface. Then use the Use Custom EUN pages option. If this option is already enabled, use the Refresh EUN pages command to make the uploaded customized EUN pages effective.

Steps to edit an existing EUN page:

In order to edit the existing custom EUN pages, follow these steps:

  • Upload the edited EUN page to the appropriate directory: configuration > eun > en
  • Refresh the EUN pages using the CLI command: advancedproxyconfig > EUN > Refresh EUN pages

It is necessary to refresh the EUN pages because proxy loads the latest EUN page into memory when it initially comes up. Any page that has been altered while the proxy has been running is not effective until the proxy is reloaded with the updated page.
