Configure Cisco Unified Communications Manager Groups¶
In VOSS-4-UC 10.x/11.5(x), use Cisco Unified CM Groups to configure Cisco Unified Communications Manager groups.
A Cisco Unified Communications Manager group specifies a prioritized list of up to three Cisco Unified Communications Managers. The first Cisco Unified Communications Manager in the list serves as the primary Cisco Unified Communications Manager for that group, and the other members of the group serve as secondary and tertiary (backup) Cisco Unified Communications Managers.
Each device pool has one Cisco Unified Communications Manager group that is assigned to it. When a device registers, it attempts to connect to the primary (first) Cisco Unified Communications Manager in the group that is assigned to its device pool. If the primary Cisco Unified Communications Manager is not available, the device tries to connect to the next Cisco Unified Communications Manager that is listed in the group, and so on.
Cisco Unified Communications Manager groups provide important features for your system:
- Redundancy - This feature enables you to designate a primary and backup Cisco Unified Communications Managers for each group.
- Call processing load balancing - This feature enables you to distribute the control of devices across multiple Cisco Unified Communications Managers.
For most systems, you need to have multiple groups, and you need to assign a single Cisco Unified Communications Manager to multiple groups to achieve better load distribution and redundancy.
Cisco Unified Communications Manager group configuration considerations¶
Before configuring a Cisco Unified Communications Manager group, you must configure the Cisco Unified Communications Managers that you want to assign as members of that group.
After you have configured the Cisco Unified Communications Manager group, you can use it to configure device pools. Devices obtain their Cisco Unified Communications Manager group list setting from the device pool to which they are assigned.
Sign in as the provider, reseller, or customer administrator.
Note
For Shared Architecture deployment, you must sign in only as a provider or reseller admin so that only provider or reseller admins can add Unified CM.
If you are adding a new instance, ensure the hierarchy path is set to the target node for the new instance.
Perform one of the following:
- If you signed in as the provider or reseller administrator, select Device Management > CUCM > Unified CM Groups.
- If you signed in as the customer administrator, select Device Management > Advanced > Unified CM Groups.
Perform one of the following:
To add a new Cisco Unified Communications Manager group, click Add, then go to step 5.
To edit an existing Cisco Unified Communications Manager group, click on the line item in the list of existing instances. Go to step 5.
Modify the following fields as required.
Option Description Name (Mandatory) Enter the name of the new group. Auto-registration Cisco Unified Communications Manager Group Check the Auto-registration Cisco Unified Communications Manager Group check box if you want this Cisco Unified Communications Manager group to be the default Cisco Unified Communications Manager group when auto-registration is enabled.
Leave this check box unchecked if you do not want devices to auto-register with this Cisco Unified Communications Manager group.
Tip
Each Cisco Unified Communications Manager cluster can have only one default auto-registration group. If you choose a different Cisco Unified Communications Manager group as the default auto-registration group, that is, you check the Auto-registration Cisco Unified Unified Communications Manager Group check box for a different Cisco Unified Communications Manager group, the previously chosen auto-registration group no longer serves as the default for the cluster; the Auto-registration Cisco Unified Communications Manager check box displays for the previously chosen group (the original default), and the check box gets disabled for the group that now serves as the default.
Unified CM Group Items (Mandatory) Click Add (+) to select a Cisco Unified Communications Manager to add to the group. Repeat as necessary to add multiple Cisco Unified Communications Managers to the group.
Click the Remove (-) button to remove a Cisco Unified Communications Manager from the group.
Click the up and down arrow buttons to change the order of the Cisco Unified Communications Managers in the group.
Priority (Mandatory) Enter the priority number for this Cisco Unified Communications Manager in the group. The smaller the integer, the higher the priority. Selected Cisco Unified Communications Managers This field displays the Cisco Unified Communications Managers that are in the Cisco Unified Communications Manager group. Click Save.
The group appears in the Call Manager Groups list. When you click on the name of the Cisco Unified Communications Manager group in the list, the group’s characteristics are displayed.
To modify any of these characteristics, make your changes and click Save.
To delete a group, check the box to the left of the Name column in the group list, and click Delete.
Note
Verify if the Unified CM is deployed in Shared Mode. Sign in to the Unified CDM, and navigate to Device Management > CUCM > Servers. On the Publisher tab, verify the Multi-Tenant field is set to Shared.
