Hello ,
my problem is to connect a cisco 876 to a lan. When I connect to the fastethernet 0,1 ,2 , with a crossover to a pc i can connect to the router over telnet and ping it.
But when I connect the router on fastethernet 0 or 1,2,3 I can't connect to the router and on the router I'm only able to ping himself.
a debug ip packet shows:
telnet 192.168.251.1

Hello, how is the Switchport configured?
On which vlan is the Switch Management IP, VLAN1?
Maybe a show run interface xx where the router is connected to, helps us.
Will the switch route, who is 192.168.251.1 (seperate router) ?

Besides what was requested before, if the interface is down/down, make sure you are using the correct cable (straight)
