About Server Service Parameter Setup
In Cisco Unified Communications Manager Administration, use the menu path to configure service parameters.
Service parameters for Cisco Unified Communications Manager allow you to configure different services on selected servers. You can view a list of parameters and their descriptions by clicking the ? icon in the Service Parameter Configuration window.
If you deactivate a service by using Cisco Unified Serviceability, Cisco Unified Communications Manager retains any updated service parameter values. If you start the service again, Cisco Unified Communications Manager sets the service parameters to the changed values.
Consider the following information before you configure the service parameters in the Service Parameters Configuration window:
- For information about what happens to service parameter values during an upgrade, see Upgrading Cisco Unified Communications Manager.
- To configure service parameters, you must select a single server and a single service on that server. After you make the selection
you can configure parameters for the service on that single serve and on others that apply to the service on all servers within
the cluster; these get marked as clusterwide.
Unlike enterprise parameters that apply to all services, each service gets configured with a separate set of service parameters.
- Feature services, which display under Service Activation and Control Center–Feature Services in Cisco Unified Serviceability, can display as active or inactive in the Service Parameters Configuration window. If you activated the feature service in Cisco Unified Serviceability, the service displays as active in the Service Parameters Configuration window; for example, Cisco CallManager (active). If you have not activated the feature service, the service displays as inactive in the Service Parameters Configuration window.
- Network services, which display under Control Center–Network Services in Cisco Unified Serviceability, always display as active in the Service Parameters Configuration window; for example, Cisco DRF Master (active). With network
services, you do not need to start the service in Cisco Unified Serviceability because it automatically runs on the server after the Cisco Unified Communications Manager installation/upgrade.
In the Service Parameters Configuration window, be aware that network services display as active even for dummy nodes, which are servers that display in the Server Configuration window in Cisco Unified Communications Manager Administration but that do not have Cisco Unified Communications Manager installed on them.
For more information about Cisco Unified Communications Manager services, see the Cisco Unified Serviceability Administration Guide.
- In the Server drop-down list box in the Service Parameter Configuration window, all servers, including dummy nodes, display as active; for example, <server name> (active). In this case, active means that you provisioned the server in Cisco Unified Communications Manager Administration.
- If you deactivate a service by using Cisco Unified Serviceability, Cisco Unified Communications Manager retains any updated service parameter values. If you start the service again, Cisco Unified Communications Manager sets the service parameters to the changed values.
- Clicking the Set to Default button updates all parameters to the suggested value, which is the default that displays on the right side of the parameter. If a parameter does not have a suggested value, Cisco Unified Communications Manager does not update the value when you click the Set to Default button; for example, the Mobile Voice Access service parameter for the Cisco CallManager service does not display a suggested value, so clicking the Set to Default button does not change the value that you enter for this parameter.
Caution |
Some changes to service parameters may cause system failure. Cisco recommends that you do not make any changes to service parameters unless you fully understand the feature that you are changing or unless the Cisco Technical Assistance Center (TAC) specifies the changes. |
Note |
You can configure a SIP trunk to use a DNS SRV port on a Cisco Unified Presence server as a destination. If you use a SIP trunk with a DNS SRV destination to configure the CUP Publish Trunk service parameter and then modify the DNS record, you must restart all devices (phones) that previously published, so they point to the correct Cisco Unified Presence server destination. |
