Licensing

Licensing

This chapter provides information about licensing in Cisco Unified Communications Manager Administration.

Licensing description

Use licensing in Unified Communications Manager Administration to accurately track the number of users that are connected to Unified CM, including Cisco and third-party phones that run SIP, and compare it with the number of user licenses that have been purchased.

License management is handled primarily through Enterprise License Manager. For more information, refer to the Enterprise License Manager User Guide.

Licensing-related windows

The configuration windows in the following table support licensing in Cisco Unified Communications Manager Administration:

Table 1 Licensing Windows in Cisco Unified Communications Manager Administration

Window

Description

Main window

After you log in to Cisco Unified Communications Manager Administration, messages may display that indicate the current state of licenses for Cisco Unified Communications Manager. For example, if the Unified CM currently operates with an insufficient number of licenses, you must upload additional license files.

System > Licensing > License Usage Report

This window displays the current license usage on the system.

The License Type column lists the various types of licenses:

  • Essential
  • Basic
  • Enhanced
  • Advanced
  • Premium
  • Professional
  • TelePresence Room

Also listed in the License Type column are the total number of users (TotalUsers) and the total number of devices (TotalDevices).

The Current Usage column identifies the number of licenses in use for each type of license.

The Report column links to detailed reports on the users and devices of each license type.

System > User Management > End Userm

This window also displays the License User for Unified CM IM and Presence check box (under Service Settings), which triggers Unified CM to check with Enterprise License Manager for appropriate user licensing.

This window also displays the Enable Mobility check box, which triggers Unified CM to check with Enterprise License Manager for appropriate user licensing.

System > Device > Phone

This window displays the Device is Active message, which triggers Unified CM to check with Enterprise License Manager for appropriate user licensing.

Unified CM licensing for users

Unified CM communicates with the Enterprise License Manager to express its licensing requirements. All licensing for Unified CM is centralized and held on the Enterprise License Manager. When phones or other services are provisioned in the Unified CM, the Unified CM asks Enterprise License Manager for appropriate licensing. At that point, licenses are either decremented or put into a state of non-compliance. Similarly, when phones or services are de-provisioned from the Unified CM, licenses are incremented and/or put back into a state of compliance on the Enterprise License Manager.

Licenses in the non-compliant state for Unified CM are enforced after a 60-day grace period. Unified CM enforcement requires the following service degradation:

  • Devices and Users cannot be provisioned. Changing the configuration of a user that affects licensing (for example, the Enable IM and Presence and the Enable Mobility checkboxes) is not allowed.
  • Devices and Users cannot be de-provisioned. Any configuration changes that involve licensing (for example, disabling IM and Presence or Mobility) is allowed.

For specifics on licensing operations, please refer to the Enterprise License Manager User Guide.

Generate a license usage report

Use the license usage report to display the total license capacity and the number of licenses in use. This tool generates a report that lists the total number of available licenses. The license unit report also displays the software license version that is installed on the Unified CM server.

For more information, refer to the Enterprise License Manager User Guide.

Alarms alerts and license status notification

Unified CM identifies the state of a license; that is, if it is missing, if it is a demo license, if it is an invalid license, or if it is an uploaded license. In addition, Unified CM Administration warns you whether Unified CM currently operates with starter licenses, with an insufficient number of licenses, or with an incorrect software feature license. For more information on this topic, see Licensing-related windows.


Tip


If the status is Invalid, verify that the license files have been obtained with a correct license MAC; that is, issue the show status cli command from the command line interface to obtain the license MAC and compare that value to the value that displays in the contents of the license file, which you view in the License File Upload window.


The following alarms get generated for licensing:

Alarm

Description

Recommended Action

CiscoElmNotConnected

Enterprise License Manager Not Connected (WARNING ALARM)

Connect Enterprise License Manager to the product

CiscoNoProvisionTimeout

The grace period for licensing has expired (WARNING ALARM)

Upload additional licenses. Verify that Enterprise License Manager is connected to the product.

CiscoSystemTimeChange

System time has changed (INFORMATIONAL_ALARM)

Determine why the system time changed.

CiscoGraceTimeLeft

Grace period countdown towards no provisioning allowed (INFORMATIONAL_ALARM)

Upload additional licenses. Verify that Enterprise License Manager is connected to the product.

CiscoSystemInOverage

System is in overage which means licensed resource limit has been exceeded on the system (WARNING_ALARM)

Upload additional licenses. Verify that Enterprise License Manager is connected to the product.

CiscoSystemSecurityMismatch

Certificate Mismatch between Cisco Unified Communications Manager and Enterprise LicenseManager (ERROR_ALARM)

Verify Enterprise License Manager certificates. This could be a "man-in-the-middle" attack.


Tip


To find these alarms, access the JavaApplications Alarm Catalog in Cisco Unified Serviceability. See the Cisco Unified Serviceability Administration Guide for more information on alarms.


If Unified CM does not have the appropriate license file, an alert gets generated; for information on alerts, see the Cisco Unified Real Time Monitoring Tool Administration Guide.

For DNS, make sure that you map the IP addresses of all servers, including dummy nodes, to the hostnames on the DNS server. If you do not perform this task, Unified CM generates alarms that the License Manager service is down.
