Setting up SVI's on a Catalyst 3550-12G

When you create an SVI, it does not become active until you associate it with a physical port. How do you associate an SVI with a physical port?

You need to have an port in the VLAN of the SVI for the interface to go up/up. This is due to the auto state feature. Here is an example for VLAN 3

config terminal

vlan 3

exit

interface vlan 3

ip address x.x.x.x y.y.y.y

interface gig 0/1

switchport mode access

switchport access vlan 3
