MLPP Domain Configuration Settings

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.

Table 20-1 describes the MLPP domain configuration settings. For related procedures, see the "Related Topics" section.

Table 20-1 MLPP Domain Configuration Settings 

Field	Description
MLPP Domain Information
Domain Name	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.
Domain ID	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.

Note You can add secure MLPP over SIP trunks by configuring a Resource Priority Namespace Network Domain and Resource Priority Namespace List. See Configuring a Resource Priority Namespace Network Domain, page 21-3 and Configuring a Resource Priority Namespace List, page 22-3.

Finding an MLPP Domain

Because you might have several MLPP domains in your network, Cisco Unified Communications Manager Administration lets you locate specific MLPP domains on the basis of specific criteria. Use the following procedure to locate MLPP domains.

---

Note During your work in a browser session, Cisco Unified Communications Manager Administration retains your MLPP domain search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified Communications Manager Administration retains your MLPP domain search preferences until you modify your search or close the browser.

---

Procedure

---

Step 1 Choose System > MLPP> Domain > MLPP Domain.

The Find and List MLPP Domains window displays. Records from an active (prior) query may also display in the window.

Step 2 To find all records in the database, ensure the dialog box is empty; go to Step 3.

To filter or search records

•From the drop-down list box, select a search pattern.

•Specify the appropriate search text, if applicable.

---

Note To add additional search criteria, click the + button. When you add criteria, the system searches for a record that matches all criteria that you specify. To remove criteria, click the - button to remove the last added criterion or click the Clear Filter button to remove all added search criteria.

---

Step 3 Click Find.

All matching records display. You can change the number of items that display on each page by choosing a different value from the Rows per Page drop-down list box.

---

Note You can delete multiple records from the database by checking the check boxes next to the appropriate record and clicking Delete Selected. You can delete all configurable records for this selection by clicking Select All and then clicking Delete Selected.

---

Step 4 From the list of records that display, click the link for the record that you want to view.

---

Note To reverse the sort order, click the up or down arrow, if available, in the list header.

---

The window displays the item that you choose.

Deleting an MLPP Domain

This section describes how to delete an MLPP domain from the Cisco Unified Communications Manager database.

Before You Begin

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, refer to 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.

Procedure

---

Step 1 Find the MLPP domain by using the procedure in the "Finding an MLPP Domain" section.

Step 2 From the list of matching records, choose the MLPP domain that you want to delete.

Step 3 Click Delete.

Step 4 When prompted to confirm the delete operation, click either OK to delete or Cancel to cancel the delete operation.
