Cisco Unified Communications Licensing with Cisco Prime License Manager PLM

By | February 1, 2018

Hello all, it’s been a while after posting an article here. I have received lot of request about How to use Prime License Manager (PLM Server) and the license architecture of Cisco Unified Communications Manager 11.5 and Cisco Unity Connection 11.5.

Cisco Unified Communications Licensing after 9.X version till 12.X is pretty similar via Cisco License Manager. CUCM 12 uses entirely different method of licensing called Smart Licensing.

The reason being posting this article here about Cisco PLM even after the release of CUCM 12 release because there are still a quite large number of users in the market who uses previous versions of Cisco Call Manager other than 12.X

Well, let’s talk about PLM,
What is Cisco Prime License Manager?
Cisco Prime License Manager (formerly Cisco Enterprise License Manager or Cisco License Manager) provides hassle free, enterprise-wide based license management across major UC products (CUCM, CUCM and CER). Cisco Prime License Manager handles license fulfillment, allocation and provides universal usage status and reports.

Cisco Prime License Manager (PLM) also supports multiple clusters and multiple versions of products, such as Cisco Unified CM versions 9.X, 10.X and 11.X (Not 12.X)

Cisco Prime License Manager (PLM) is co-installed with your Cisco Unified Communication Manager installation. You can also install another instance of Cisco Prime License Manager (PLM).

Now, let’s see how to use Cisco Prime License Manager (PLM) to install license (demo) for an 11.5 Cisco Call Manager Custer.

When you login to CUCM, you can see license warning message if you haven’t configured any License for the cluster.
