The XD Manager OTM to IP correlates failures between the underlying optical network domain and the IP network domain. When a failure in the optical network impacts a device in the IP network, cross-domain correlation identifies both the root cause and the impacted IP facility. The XD Manager OTM to IP collects information from the following sources:

  • IP Availability Manager

  • Optical Transport Manager SONET/SDH Server for Analysis

  • Optical Transport Manager WDM Server for Analysis

  • Optical Transport Manager PDH Server for Analysis

  • Optical Transport Manager WDM-NG Server (includes both Analysis and Topology)

  • A custom cross-domain topology Inventory adapter that provides source mapping for the optical/IP network connections

    With this information, the XD Manager OTM to IP creates a cross-domain topology and monitors and correlates alarms regarding changes to elements in the topology. The VMware Smart Assurance XD Manager for OTM to IP User Guide provides more information.
