SBC SWe deployments support a domain-based licensing model referred to as Network-Wide Domain Licensing (NWDL). In contrast to node-locked licensing, a domain license is tied to an administrative domain rather than the hardware ID for a specific host server or the UUID for a specific node instance. A domain license is bound to the domain through public/private key-pairing and it defines the features and capacity allowed for all nodes within the domain. NWDL provides flexibility in cloud environments where the number and placement of nodes sometimes varies. Contact your Ribbon representative for more information on available licensing options and to complete the ordering process that is required prior to implementing NWDL.
NWDL is implemented using license management capabilities within the Insight Element Management System (EMS). The EMS provides the public key used to bind the license to the local domain and is used for associating license data with eligible nodes. The basic steps to implement domain licensing are as follows:
Refer to the License Management section in EMS documentation for specific procedures to locate and copy the public key, install a license bundle, and associate feature licenses with SBC nodes.
After these preparations are completed on the EMS, enable domain-based licensing on the SBC cluster by configuring the license mode as "domain." Save and activate the configuration. The OAM node for the cluster provides the configuration update to each SBC node in the cluster. The nodes then enable or disable features based on the license definition in their configuration.
In domain licensing mode, you can add to your existing license definition following the same process to load another license bundle file onto the EMS, and using the EMS to assign the additional features licenses to the SBC clusters. The resulting set of licenses features and capacity for the cluster is the aggregate of the existing license and the added license.
When configured for NWDL, the SBC supports a "full-capacity" option in which the counts for individual, counted license features are no longer used to limit activity on the SBC. Enabling the full-capacity feature effectively enables feature use up to the capacity of the node. Actual license usage is reported to Ribbon using EMS statistics.
The full-capacity feature requires the SBC-CAPACITY-D license key in the license file. Contact your Ribbon representative for more information on the use of the full-capacity licensing option.
The NWDL architecture permits the nodes to burst to capacity when the "D" feature ID is present (SBC-RTU-D).
If the License SBC-CAPACITY-D is present, the SBC does not need to register with the License Manager.
If the License SBC-CAPACITY-D is not present, the SBC needs to register with the License Manager within 90 days. If not, call processing fails.
Use the SBC CLI or access the SBC Configuration Manager UI from the EMS to enable domain license mode and optionally specify license capacity limits for the nodes in the cluster. Refer to Modifying SBC Cluster Configuration.
To avoid a service outage, ensure your NWDL licenses are already installed if you reconfigure an SBC cluster into domain license mode.
By default, SBC license mode is set to nodeLocked
. Use the following CLI commands to place the SBC in domain (NWDL) license mode:
% set system licenseMode mode domain % commit
Or, in the SBC Configuration Manager UI:
Use the following command to output information on the domain license bundles loaded into the system.
> show table system licenseDomainBundleInfo
Or, in the SBC Configuration Manager UI:
Go to All > System > License Domain Bundle Info The License Domain Bundle Info window opens.
The following license information is output:

The SBC SWe includes the capability to shut off calls when there is no License Manager refresh in the last 90 days. The NWDL architecture requires the user to have the node/instance register with the license manager to report the usage, and then refresh the registration periodically. This functionality is enabled by the LACK of a CAPACITY license. If the SBC instance is not successfully registered with the license manager in 90 days, the SBC stops processing calls after sending warning alarms to the user.
The SBC SWe registers with the License Manager once per day, independent of the registration status.
Feature behavior:
Action | Conditions | Result |
---|---|---|
The SBC runs with the licenseMode set to domain |
| The SBC attempts to register with the License Manager |
The SBC sends a registration request to the License Manager |
| The registration is considered as successful. |
The SBC sends a registration request to the License Manager |
|
|
The SBC sends a registration request to the License Manager |
|
|
The SBC fails to register with the License Manager for 90 days | All license counts are set to 0 | |
The License Manager returns a response field called lastCollectionTime (In addition to the registration status) (This represents the previous time the License Manager detected at least one license was consumed – either a counted license was consumed while making a call, or an on/off license is present) |
| The License Manager rejects the registration after 90 days |
The lastCollectionTime in the LicenseManager response is older than one day | The start of the grace period is not updated, even if the registration is successful | |
A licensed feature, REG-GRACE-D, is added (This is a counted license) |
NOTE: On a 1-to-1 system, the GRACE period remaining is identical on both systems. | |
All NWDL licenses on the SBC SWe expire (Example: trial license scenario) | The SBC will not attempt to register with the License Manager. When new NWDL licenses are installed, the 90 day grace period will restart. | |
An action command is added to test the License Manager settings or to trigger a new License Manager registration after a previous registration request failed. | This provides an opportunity for the operator to rectify the condition on the License Manager that caused a registration to fail, and to retry the request. | |
The installed count for any NWDL-counted license is greater than 0 | A count of 999999 is available for that license (except for REG-GRACE-D feature) NOTE: If all the license bundles containing a particular feature expire, the count for that feature reaches 0 and the calls requiring that feature do not succeed. The licenseRequired table is no longer supported to limit the license count. |
The SBC SWe identifies the addresses of the EMS servers running the License Manager Micro Service through the following methods:
