    Create login banner

    From Cisco Unified Presence Release 8.6(4), you can create a banner that users acknowledge as part of their login to any IM and Presence interface. You must create a .txt file using any text editor, include important notifications that you want users to be made aware of, and upload it to Cisco Unified IM and Presence Operating System Administration. This banner will then appear on all IM and Presence Service interfaces notifying users of important information before they login, including legal warnings and obligations. The following interfaces will display this banner before and after a user logs in:

    • Cisco Cisco Unified Communications Manager IM and Presence Administration

    • Cisco Unified IM and Presence Operating System Administration

    • Cisco Unified IM and Presence Serviceability

    • Cisco Unified IM and Presence Reporting

    • IM and Presence Disaster Recovery System

    Procedure
      Step 1   Create a .txt file with the contents you want to display in the banner.
      Step 2   Sign in to Cisco Unified IM and Presence Operating System Administration.
      Step 3   Select Software Upgrades > Customized Logon Message.
      Step 4   Select Browse and locate the .txt file.
      Step 5   Select Upload File.
      Step 6   The banner will appear before and after login on most IM and Presence interfaces.

      IPsec policy management


      Note

      IPsec is not automatically established between nodes in a cluster during installation of the IM and Presence Service.

      Create IPsec policy

      You can set up a new IPsec policy. Do not, however, attempt to create IPsec policies during an IM and Presence node upgrade.


      Caution

      IPsec, especially with encryption, will affect the performance of your system.
