The MPLS Topology Server performs CLI discovery and executes on-demand LSP ping requests. As shown in CLI discovery, LSP ping, and CLI device-access object creation and transfer, CLI discovery and LSP ping are controlled by CLI device-access objects that are created on the IP Availability Manager, through the Polling and Thresholds Console, and then imported by the MPLS Topology Server.
