Abstract:
1. A method comprising: by a network switch within a local area network (LAN), attempting to establish connectivity to a wide area network (WAN) over a plurality of ports with a first set of Internet Protocol (IP) configurations using a first set of port configurations as a current set of port configurations, wherein an IP configuration of the first set of IP configurations includes a Virtual Local Area Network (VLAN) identifier (ID), an IP address for the network switch, a subnet mask, an IP address of a gateway, and an IP address of a Domain Name System (DNS) server, wherein the network switch is coupled to a network access device that is within the LAN and that acts as the gateway to the WAN, wherein the network switch includes the plurality of ports any one of which may be coupled to the network access device and operate as a current uplink port for establishing connectivity to the WAN, wherein the network switch has the current set of port configurations that includes a respective current port configuration for each of the plurality of ports, wherein the respective current port configuration for the each of the plurality of ports identifies a set of VLAN IDs, wherein network traffic must meet a current port configuration for a specific port of the plurality of ports on which the network traffic is received or transmitted to avoid the network traffic from being blocked at the specific port; responsive to determining that connectivity to the WAN has not been established, automatically performing: responsive to determining that attempting to establish connectivity to the WAN with the second set of IP configurations did not result in connectivity to the WAN being established, automatically performing:
