B5800 Branch Gateway supports centralized licensing by WebLM where a single license file is generated in Avaya Product Licensing and Delivery System (PLDS) for multiple branches. Support for individual PLDS license files for each branch (the licensing method provided in B5800 Branch Gateway R6.1) is also an option. WebLM licensing is the recommended method for B5800 Branch Gateway R6.2 and higher. Both licensing methods are described below.
WebLM license management
B5800 Branch Gateway R6.2 supports WebLM licensing in which a single license file is generated in PLDS for multiple branches. This license file contains the host ID of the WebLM server and is managed by the WebLM server. Each B5800 Branch Gateway communicates with the WebLM server to request the required license entitlements. B5800 Branch Gateway uses the Avaya Aura System Manager WebLM server.
WebLM standard licensing model — in this model, one WebLM server is used. This model is used for enterprises where the System Manager WebLM server is able to manage all B5800 Branch Gateway licenses required for the enterprise.
WebLM enterprise licensing model — in this model, multiple WebLM servers are used. This model is used for enterprises where the licenses required for all branches in the enterprise exceed the System Manager WebLM server capacity. One WebLM server acts as a master WebLM server and hosts the license file from PLDS. The other WebLM servers(s) act as a local WebLM server and host allocation license files from the master WebLM server. Each B5800 Branch Gateway must be configured with the IP address of one of the WebLM servers.
Note The expected System Manager WebLM server capacity is about 400 branches on a loaded System Manager. The capacity would be higher on a lightly loaded System Manager. The expected WebLM capacity on a standalone Linux server is about 1,100 branches. Large deployments that exceed the System Manager WebLM capacity require additional standalone WebLM server(s) and configuration of the WebLM servers as master and local in the WebLM enterprise licensing model.
Note The correct expiration time of licenses for a B5800 Branch Gateway that uses a local WebLM server is provided on the corresponding master WebLM server. The local WebLM server shows the licenses as having an expiration time of 30 days or less. However, periodically the license expiration time on the local WebLM server is automatically refreshed and extended when the master WebLM server pushes a refreshed Allocation License File to the local WebLM.

Separate PLDS license for each branch
In B5800 Branch Gateway R6.1, an individual PLDS license file was required for each branch and installed on each branch directly. A WebLM server was not required. This licensing method is supported in B5800 Branch Gateway R6.2 for branches that cannot be connected via an enterprise WAN to a central WebLM server or for migration of installed B5800 Branch Gateway R6.1 systems. Using the WebLM licensing method is recommended, but does not have to be done as part of an R6.1 to R6.2 upgrade.
For the separate PLDS licensing method, branch licenses are issued and validated against the Feature Key serial number of the System SD card used by that B5800 Branch Gateway. That number is printed after the FK prefix on the System SD card and is also shown in the branch system configuration. This means that licenses issued for one branch cannot be used in the configuration of another branch. In the IP Office Manager application, this number appears in the PLDS Host ID field on the System page when you select System > System.
