No, SVI interfaces are now used (Switched Virtual Interfaces). You now create the VLAN at Layer-2 and then add the equivalent SVI interface -

vlan 10

name VLAN-10


vlan 20

name VLAN-20


interface Vlan10

description VLAN-10 SVI

ip address


interface Vlan20

description VLAN-20 SVI

ip address

You can also just create the VLAN at Layer-2 and not perform inter-vlan routing on the 3750. I think the older 2948G-L3 and 4908G-L3 switches were the last Catalysts to require BVI's.

He just showed you:

interface vlan 10

As I posted - you treat it like any other interface? Once the Layer-2 VLAN exists you just add the SVI with the command 'interface Vlan X' where 'X' is the VLAN number, by default it will be shutdown but a 'no shut' will bring it up. To put access ports in the vlan just make sure they are configured as access ports (switchport mode access) and they are in the right vlan (switchport access vlan X).
