I think I may have found the correct forum here. Been trying forever to make good use of the router I purchased from Cisco market during CCNA class.(871w) I wiped the initial config , thinking I was good enough to do it by commands. Slick , huh? Well never been able to get SDM to work. Main reason seems to be VLANs and fact you can't put address on fe 0 to fe 3 ports. To be brief , I can open a terminal for commands log on to router and set an address on fe 4 , the wan port, and ping both ways to and from the laptop. Wish to do two things if I can get help. Set up VLANs so I can connect my local net. And reinstall SDM , which doesn't connect because there is no correct IP address for it. When I try to follow cisco manual / instructions it always directs towards configuration for switches regarding the VLANs and that is a whole different animal indeed.
Please anything may help, appreciate it. Thanks Doug M.
