The invention discloses monitoring method and system for process level network virtual secondary circuit based on intelligent switching. The monitoring method and system for the process level network virtual secondary circuit based on intelligent switching comprises the following steps: A: quantitatively analyzing identification and parameters of the supporting data of the process level network virtual secondary circuit, switching time delayed measuring, reporting and collecting, switching process path tracing and virtual connection and switching resource consumption data; B: identifying and looking up indentify (ID) communication data of the supporting data; C: counting the parameters of the supporting data such as data traffic, communication port speed, switching delay, switching success rate, switching internal resource consumption, port queue depth and port priority level; D: real-time monitoring real-time state of the supporting data, a switching device and a network access device based on garp multicast registration protocol (GMRP); E: achieving linkage and unified management of information from step A to step D, and conducting processing on exceptions of data in the switching device.
