Abstract:
In a case where reconnection of a cable is performed by replacement of a network device, an erroneous connection detection unit of a network management server compares opposing identification information of current value information and opposing identification information of expected value information, compares group identification information before the replacement of the network device and group identification information after the replacement of the network device, with reference to port configuration information, and determines the presence or absence of erroneous connection of the cable, on the basis of a result of the comparison.
Abstract:
It is provided an authentication method for realizing a network authentication function for an authentication system, the authentication system including an authentication server for authenticating a terminal used by a user, and a switch for mediating an authentication sequence between the terminal and the authentication server. The authentication method includes steps of: providing, by the switch, identification information for identifying the switch to the authentication server in the authentication sequence; authenticating, by the authentication server, an authentication request transmitted from the terminal; transmitting, by the authentication server, an authentication result of the authentication to the switch based on the provided identification information on the switch; and authenticating, by the switch, access from the terminal based on the authentication result received from the authentication server.
