I am quite a bit rusty from my days of networking. I am trying to setup my lab so I purchased 3 cisco 2501 to study for my CCNA, my question is? I have 2 serial interfaces and 1 AUI for ethernet on each router. How can I configure the Ethernet interface, if I don't see it on the configuration. From the CLI command I issue the command show ip int brief. But It only shows the 2 serials but no E0 interface. Any help will be greatly appreciated.
PS. I do have an Ethernet Transceiver connected to the AUI port on the router with a straight through cable going into a 2950 switch.
