svi v. vlan...

keith barker says that a switched virtual interface is a logical interface created from an existing vlan... this is an excellent explanation of this vague difference... here you can download that video in zip format, and i suggest you do....

the only requirement to creat a vlan is a number, period... to further create the svi, you must type int vlan 99, after creating the vlan... there are no other requirements to creating the svi...

dsw2(config)#vlan 99
dsw2#sh vlan brie
