Abstract
The present invention provides a method, apparatus, and communication system (100) for determining the status of a transmission link (108) between a first port (105) of a first device (104) and a second port (107) of a second device (106). The communication system (100) includes a management device (102). The management device (102) includes an input port (103) and a processor (116). The management device (102) receives a first status of the first port (105) and a second status of the second port (107) on the input port (103). The management device (102) calculates at the processor (116) the status of the transmission link (108) based on the first status and the second status.
