What could be the reason a cisco gigabitethernet interface gives status down protocol down and doesn't change this while doing a "no keepalive" on the interface? (nothing connected to the interface).
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 10.0.0.1 YES NVRAM down down
Normaly this would give an "up down" status even if nothing is connected.
Any ideas? I want to use the "no keepalive" for testing purposes (when nothing is connected).
