License Client

The License Client requests component licenses from the License Server. The License Client tab allows you to enable a node as a client and configure the prerequisites.

Term	Description
Enabled	Allows you to either enable or disable a node to be a License Client.
License Manager Address	The hostname or IP address where the License Manager is configured.
License Manager Port	Enter the Port of the License Manager.
Preallocated Device Count	The minimum number of device count /HTTP count acquired from the server. The intent is to allow gateway to operate smoothly when the license server is not available at the time of request. It is possible to reduce the number of requests to the server, thus improve performance as long as gateway is using less or equal to the preallocated device count.
Preallocated HTTP Count
Device Usage	The number of device licenses used.
HTTP Connection Usage	The number of HTTP Connection licenses used.
Next Sync	The date/time of the next synchronization.
Expiration	The date/time of the license expiration.
Last Sync	The date/time of the last synchronization.
Features	With the new license pooling, base features are also shared from the server and this field provides a list of features that are shared.

License Client node configuration

To configure a node as a License Client:

The HTTP Server is used for the communication between the License Client and the License Manager. The HTTP Server must be configured and Started. For more information, see: HTTP Server.
Configure the License Manager Address and License Manager Port parameters.
- The License Manager Port must be an HTTP over TLS (https) port. The default https value for the HTTP Server is 8443.
- If the License Client's Last Sync status is Operation has timed out, then make sure the License Manager Port parameter is configured for an https port (the default is 8443) and not an http port such as 8080.
To stop participating as a License Client, remove the License Manager Address parameter.
Click Save.

License Client node run time behavior

The License Client run-time behavior is:

When license client is used, all the local licenses will be invalidated. Only use this feature, if you have a valid license server.
Releases an acquired license back to the License Manager when the device/http/gateway is Stopped.
Releases an acquired license back to the License Manager when a device/http/gateway is Disabled.
Nodes (the order of which is not defined) using an acquired license will be disabled if the License Client can not renew the license lease and the lease duration expires.
