On my local 3560 switch, I defined vlan1 as shown below. Then I see that in spite of my 'no shut' command', line protocol remains down. Why is like that? Of course from there I can't ping it. What do I need to do in order to make this vlan turns to 'line protocol up'?
#show int vlan1
Vlan1 is up, line protocol is down

I believe you need at least 1 interface on VLAN 1 UP/UP - Connected - for the VLAN to show up/up

You need at least one active port in the vlan in order to bring up the SVI .

Is there at least one interface with something plugged into it which is in VLAN 1? There needs to be an up/up interface within the VLAN for the VLAN to be in an up state.

That makes sense. Since I made the port fa0/23 and fa0/24 as 'no switchport', then those are plugged but they are no longer part of vlan1, hence this behavior. I will plug something in there later. Thanks!
