I have a 3745 with a 34 port ethernet card.
I configure port 2/0 as a trunk. I create interface vlan 1 and assign it an IP and no shut.
Now, port 2/0 is a trunk and it's up. But why is interface vlan 1 showing "up, down"?
The trunk has native vlan set to 1 by default so - interface vlan 1 should be "up, up" but is isn't!
Anyone explain why?
