What model switches are you stacking? If 3750s with stack cables, they will look like one switch. YOu don't have to do anything special. If it's a 3550/3560 do this:


- Set all switches to VTP mode transparent

vtp mode transparent

- Set all switches vtp domain name so that it is not NULL

vtp domain MYVTP

- Create vlans on all switches

vlan 100

vlan 101

vlan 102


The ports that connect to one another should look like this:


interface GigabitEthernet0/1

switchport trunk encapsulation dot1q

switchport mode trunk

spanning-tree portfast disable


The user ports of the switch should look like this:


interface GigabitEthernet0/7

switchport host

! this is a script that does a few commands

switchport access vlan 100

spanning-tree portfast


This is just a bare minimum configs, but it should get the 4 talking to one another. If your switch is a completely different model, post that here. That will help.
