ABSTRACT:
A method and system are provided for obtaining logical performance data for a network circuit in a data network. The network circuit includes both a logical circuit and a physical circuit. A legacy physical element module sends a request for logical performance data to a logical element module through a network management module in communication with the legacy physical element module and the legacy physical element module. Based on the request, the logical element module retrieves the logical performance data from one or more network devices in the network and transmits the data to the legacy physical element module through the network management module. Upon receiving the logical performance data, the legacy physical element module uses the performance data to troubleshoot the physical circuit. The network device may be a switch. The circuit may be a frame relay circuit or an ATM circuit.
