How would I go about finding the names of all of the interfaces (e.g. FastEthernet2) that can be configured within the IOS?


Is there a place I can find this information without having the router accessible?

The Cisco 1811 and 1812 provide high-speed broadband or Ethernet access through two 10/100BASE-T Fast Ethernet WAN ports and also provide integrated WAN backup through a V.92 analog modem (Cisco 1811) or ISDN S/T BRI interface (Cisco 1812). The Cisco 1811 and 1812 routers are focused on Ethernet access and are designed to be offered as customer premises equipment (CPE) in Metro Ethernet deployments. The eight-port switch is sufficient for connecting multiple devices and the optional PoE capability can supply power to IP telephones or other devices.
