Interface in shutdown, Link-LED stays on.

I shutted down the GigabitEthernet-I/F on a cisco3845-router. The Link-LED stay on. Shouldn`t the Link-LED went off when the Interface is Administratly down?

The other side off the Cable is connected to a Catalyst. Does anybody have a expaination for this behavior?

Are you sure it was not the other interface of teh 3845 that was shut?

Yes, I am sure. It's the correct Interface.

Are you using the CLI to issue the command? The reason I ask is I have had instances where issuing the command via a GUI did not acutally apply the command.

This is rather peculiar...

Is the link light amber or green?

I would expect an up link to be green, down link no light, and admin down to be amber.

The link lights are green - on both sides (on the cisco3845 and the calalyst ws-x5225-module)
