1) make the port an access port
2) block 01-00-0C-CC-CC-CC (used by CDP too)
3) use transparent vtp v1 & different domain
4) block vlan 1 (although actually that's not possible)

You can also use "switchport nonegotiate" to turn DTP off, if you're getting vtp mismatch messages 
(different vtp domains on each side).
