Abstract:
A network apparatus for a wide area network (WAN) includes a plurality of ports through which a local area network (LAN) and the WAN are connected; an active-port selecting unit that selects an active port from among the ports, and identifies a port other than the active port as a standby port; and a notifying unit that notifies an interface device for the LAN via the standby port that a line connected to the standby port is in a standby mode.
