With this release, Cisco Prime License Manager supports the encryption license which enables the higher levels of the product encryption for the registered products. Some newer Cisco products, such as Cisco Unified Communications Manager Release 11.5(1)SU3, and Cisco Unity Connection, Release 11.5(1)SU3 require an encryption license to run the product in mixed mode.

Procure the encryption license along with the PAK and install it. For more details on buying the licenses, see the Ordering Guide at http://www.cisco.com/c/en/us/partners/tools/collaboration-ordering-guides.html.

For more details on encryption fulfillment, see "License Management" chapter of the Cisco Prime License Manager User Guide at http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-license-manager/products-user-guide-list.html.

With this release, the command privilege level for the following two CLI commands has changed from 0 to 1. Only users with a minimum privilege level of 1 have access to run either of these commands:

• license management set log level core_services

• license management set log level product_instances

For more information about the license management set log level commands, see the "Cisco Prime License Manager CLI Commands" chapter of the Cisco Prime License Manager User Guide at http://www.cisco.com/c/en/us/support/cloud-systems-management/prime-license-manager/products-user-guide-list.html.

With this release, Cisco Prime License Manager does not support RC4 Ciphers and they are arcfour256, arcfour128, and arcfour.

With this release, Cisco Prime License Manager supports the configuration of a minimum Transport Layer Security (TLS) version. For example, you can set your system to support TLS 1.2, this would ensure a secure connection for Cisco Prime License Manager and it accepts TLS 1.2 connections only.

The supported TLS versions are TLS 1.0, 1.1, and 1.2 with version 1.0 as the default minimum supported version. After you reconfigure the minimum TLS version, TLS versions that are the same as, or higher than, the TLS minimum are supported.

Enter the command set tls min-version tlsversion to set the minimum version of TLS that is supported by the system. You can use, the command show tls min-version to view the minimum configured version of TLS.

For more information about the minimum TLS version commands, see the "Set Commands" chapter and the " Show Commands" chapter of the Command Line Interface Reference Guide for Cisco Unified Communications Solutions at http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html.
