PROBLEM TO BE SOLVED: To solve the problem that it is not possible to easily determine which of the failure of an opposite device and the failure of a connection line has occurred in a network connection device achieving a redundant configuration.SOLUTION: In a network system having first communication equipment and second communication equipment connected to a redundant link configuring a link aggregation, the first communication equipment includes: a first port connected to a redundant link; a second port connected to the second communication equipment; and a third port having attributes different from those of the second port. The first communication equipment includes: a monitoring part for monitoring the state of the port connected to the second communication equipment; and a control part for determining the state of a port group configured for each attribute of the port connecting the first communication equipment and the second communication equipment on the basis of the monitoring result of the port belonging to the port group, and for determining setting for a predetermined resource on the basis of the combination of the states of the plurality of port groups, and for performing control to achieve the setting.SELECTED DRAWING: Figure 1 |
