are you wouldn't do or don't want to do? Such a cultivated person in the future also deserve to production environment?

Sorry words a bit heavy, hope you good good study,

I never use the simulator, the hand also have no simulator, with 3750 directly handle to knock,

The first step: (all ports? I see you only column 2, if there are many copy oneself play)
Switch5 configuration:
The conf t
Int fa0/1
The switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk allowed vlan all
No shut
Int fa0/2
The switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk allowed vlan all
No shut

The Switch configuration:
The conf t
Int fa0/1
The switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk allowed vlan all
No shut

The Switch configuration:
The conf t
Int fa0/1
The switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk allowed vlan all
No shut

The second step: (only)
according to the questionThe Switch configuration:
The conf t
VTP mode server

The Switch configuration of 6 and 7 is the same:
The conf t
VTP mode client


Finally, to reiterate:
Be sure to please the basic network to learn , if there is no ! You have homework, be sure to use the simulator or actual airplane practice personally slowly groping ! Network engineers by 30% 70% by practice exercise, if you don't want to go for it and also become the net work in the future, I hope you don't do a will only call for help secondary waste !

Or that sentence, please study hard!
