Abstract: A multi-port switch is provided having an Ethernet switching section for connecting and switching among network devices and includes at least three ports, a network management module operating according to SNMP, and a monitoring module operating according to RMON. The switch can arrange the ports to operate as virtual local area networks (“VLANs”). The switch is secured with a network element that is part of a network device. In a system including the multi-port switch, an automated teller machine local area network is connected to one port, a customer data LAN is connected to a second port, and a router is connected to a third port. The switch arranges the three port connections into two VLANs, each VLAN including the router. The switch alternately switches between the VLANs in order to enable the ATM LAN and the customer data LAN to communicate with an external network. The switch is secured with or located inside one of the ATMs in the ATM LAN.
