About interface status.

Using GNS simulator with only one router without any connections, I have noted that with the "no shutdown" command

an ethernet interface remains in a down/down state, as I expected.

If I configure an IP address instead, the "no shutdown" command take the interface in a up/up state, as I did not expected.

As there is not the cable, I expected that there was a problem with the keepalive message.

Is there a problem with the simulator? How do the router work in real world?

Thanks.

Hi,

I have the same in GNS.

In the real world, the interface will not go UP because there is no signal...It will stay down only when it gets a link from a device e.g. it will goes up.

Thats my view...

Hi Helmer,

you are right and adding few more information.

In the real world scenario,Sh int <> will show port is down and protocol is down.

Thanks & Regards
