"Vlan1 is up, line protocol is down" What is wrong? 2

[BigD12]

I'm a Newby, Please forgive any Ignorance on my Part;
and thanks for any assistance you may offer.


After running the setup on a Cisco 3550-48 Switch, I get the following:

"Vlan1 is up, line protocol is down"

How do I bring line protocol up?



This is my config file:

no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption
!
hostname WET-3548-1
!
enable secret
enable password
!
ip subnet-zero

do a no shutdown on vlan 1


interface vlan1
no shutdown

On some switches the interfaces remain down until you actually connect a device to that vlan. This might be the case if you have already issued a no shut command on the interface.

I issue the "no shutdown" on Vlan1 but I'm still getting a "line protocol is down".

by the way, the swith is connected to the network via the Gigabit interface.

You must have an active client connection on vlan 1 for the SVI to go to an up/up condition . Once there is a live client on the switch you will see vlan 1 up/up .
