ABSTRACT:
Systems and methods to monitor communications to identify a communications problem are disclosed. An example method to monitor communication includes mirroring a first port on a first network element communicatively coupled to a virtual circuit to a second port on a second network element communicatively coupled to the virtual circuit, mirroring a third port on a third network element coupled to the virtual circuit to the second network element, monitoring mirrored communications data at the second network element by receiving communications data on the second port that are sent to the first port from the third port or from the first port to the third port, and analyzing the monitored communications data to identify a communications problem based on a difference between communications data mirrored from the first port and communications data mirrored from the third port.
