MLPP Domain Configuration Settings
In Cisco Unified Communications Manager Administration, use the System > MLPP> Domain > MLPP Domain menu path to configure MLPP domains.
An MLPP domain specifies the collection of devices and resources that are associated with an MLPP subscriber. When an MLPP subscriber that belongs to a particular domain places a precedence call to another MLPP subscriber that belongs to the same domain, MLPP service can preempt the existing call that the called MLPP subscriber is on for a higher precedence call. MLPP service availability does not go across different domains.
Tips About Configuring MLPP Domains
You can add secure MLPP over SIP trunks by configuring a Resource Priority Namespace Network Domain and Resource Priority Namespace List. See "Resource Priority Namespace Network Domain Configuration Settings" section on page 18-1 and "Resource Priority Namespace List Configuration Settings" section on page 19-1.
Tips About Deleting MLPP Domains
You cannot delete an MLPP Domain that any device is using. To find out which devices are using the MLPP domain, from the MLPP Domain Configuration window, choose Dependency Records from the Related Links drop-down list box and click Go. If the dependency records are not enabled for the system, the dependency records summary window displays a message. For more information about dependency records, see the "Accessing Dependency Records" section on page A-2. If you try to delete an MLPP Domain that is in use, Cisco Unified Communications Manager displays an error message. Before deleting an MLPP Domain that is currently in use, you must perform either or both of the following tasks:
•Assign a different MLPP domain to any devices that are using the MLPP domain that you want to delete.
•Delete the devices that are using the MLPP domain that you want to delete.
Using the GUI
For instructions on how to use the Cisco Unified Communications Manager Administration Graphical User Interface (GUI) to find, delete, configure, or copy records, see the "Navigating the Cisco Unified Communications Manager Administration Application" section on page 1-13 and its subsections, which explain how to use the GUI and detail the functions of the buttons and icons.
Configuration Settings Table
Table 17-1 describes the MLPP domain configuration settings. For related procedures, see the "Related Topics" section.
Table 17-1 MLPP Domain Configuration Settings
Enter the name that you want to assign to the new MLPP domain. The name can comprise up to 50 alphanumeric characters and can contain any combination of spaces, periods (.), hyphens (-), and underscore characters (_). Ensure that each MLPP domain name is unique.
Note The name of the default MLPP domain specifies Default. The Default domain cannot be changed nor deleted.
Enter a unique six-character hexadecimal MLPP domain ID. Valid values are numeric characters 0 through 9 and alphabetic characters A through F. Ensure that each MLPP domain ID is unique.
Domain IDs must fall in the range between 000001 and FFFFFF. (000000 is reserved for the default MLPP domain ID.)
Note Use leading zeroes for values lower than 100000.
