Remote License Server IP: IP address of the License Server.
The device periodically checks with the License Pool Manager Server for SBC capacity
licenses. The License Pool Manager Server identifies the device by serial number. If it has
an SBC license for the device, it sends it to the device. If the device's installed License Key
already includes SBC capacity figures, the SBC license allocated from the pool is simply
added to it (but up to the device's maximum supported capacity capabilities). For
standalone devices, you
license to take effect. If communication with the License Pool Manager Server is lost for a
long duration, the device discards the allocated SBC license (i.e., expires) and resets with
its initial, local SBC license according to the local License Key. This mechanism prevents
misuse of SBC licenses allocated by the License Pool Manager Server.
When the device operates in High-Availability (HA) mode, the active and redundant
devices are installed with the new SBC license from the License Pool Manager without
affecting traffic. This is achieved by a hitless license upgrade mechanism, whereby the
License Pool Manager first downloads the license to the redundant device, resets it, and
then triggers the devices to perform an HA switchover. It then downloads the same license
to the previously active device (now the redundant), resets it, and then triggers another HA
switchover. Therefore, currently active calls are maintained throughout the process.
The device sends the following SNMP alarms relating to the allocation/de-allocation of SBC
licenses by the License Pool Manager Server:

acLicensePoolInfraAlarm (OID 1.3.6.1.4.1.5003.9.10.1.21.2.0.106)

acLicensePoolApplicationAlarm (OID 1.3.6.1.4.1.5003.9.10.1.21.2.0.107)

acLicensePoolOverAllocationAlarm (OID 1.3.6.1.4.1.5003.9.10.1.21.2.0.125)
For more information on the alarms, refer to the SNMP Reference Guide.
Note:
•
No configuration is required on the device; the License Pool Manager Server
controls the allocation/de-allocation of its resource pool to the managed devices.
For more information on the License Pool Manager Server, refer to the OVOC
User's Manual.
•
The allocation/de-allocation of SBC licenses to standalone devices by the License
Pool Manager Server is service affecting and requires a device reset.
•
For HA systems, the License Pool Manager Server automatically allocates an
equal number of SBC licenses (sessions) to both the active and redundant
devices. For example, if the License Pool Manager Server allocates 200 sessions
to the active device, it also allocates 200 to the redundant. Thus, it is important to
take this into consideration when ordering a license pool.
•
If the device is restored to factory defaults, the SBC licenses allocated by the
License Pool Manager Server are removed and the SBC licenses from the locally
installed License Key are applied.
•
If the device is allocated an SBC license by the License Pool Manager Server that
exceeds the maximum number of sessions that the device can support, the device
sets the number of sessions to its maximum supported.
