Discovery

The Adapter for Alcatel-Lucent 5620 SAM EMS does not perform SNMP polling of the network element through a traditional discovery process; rather, the Adapter gets all topology information from the Alcatel-Lucent 5620 SAM EMS database.

The Adapter provides the following discovery options for initiating discovery and ensuring that the topology is correctly maintained:

• Full discovery—Manually initiated or scheduled rediscovery for all topology elements. This process examines all Alcatel-Lucent 5620 SAM EMS physical objects and adds or updates the topology in all appropriate Domain Managers at the same time.

• Incremental additions/deletions/changes—The Adapter receives updates to the topology of the Alcatel-Lucent 5620 SAM EMS. Incrementally applied status updates are applied to the appropriate Domain Manager and automatically propagated to other Domain Managers that rely on that information. This is sometimes referred to as incremental discovery.

• Partial rediscovery—Manually initiated or scheduled rediscovery for selected topology elements such as a single router and its elements, or service (logical) items only. This process updates the topology in the appropriate Domain Managers at the same time.
