Installing the license file

Installing the license file

Important: When upgrading your CNA servers to version 3.0.3, you must obtain a new license file for your servers. Version 3.0.3 software will not work with a license file from an earlier software version.

Once you obtain the license file, you can install it on your CNA server. If your CNA deployment includes multiple CNA servers, install the license on one CNA server. This license will serve as the master license for all CNA servers in your deployment. After installing the license, you must then configure all other CNA servers to retrieve licensing information from the server hosting the master license.

NOTE: You cannot change the server hosting the master license from one server to another. The license is associated with the MAC address of port eth0 on one server and will not worked if installed on a different server.

To install the license on the CNA server:

Copy the generated license file to your CNA system by using the restore license <file-url> command.

Example:

restore license c7-a11-large.xml

Installation complete.

When license installation is complete, the license is placed in the WebLM directory on the CNA server. At startup, the CNA system communicates with the WebLM server application to obtain the following information:

available features
number of monitored endpoints that are configured on the system for each feature

The number of monitored endpoints includes both the total number of active measurement targets and CNA agents that are registered.

Configure each CNA server to retrieve the license file from the license server. Use the license server ip-address <ip address>, where <ip address> is the IP address of the CNA license server.
Verify that the license was properly installed by using the show license command.

The output displays the license file details including: the license mode, major software version, feature tier, enabled feature models, and total number of monitored endpoints.

Each of these CNA feature licenses defines the number of monitored endpoints that are allowed.
