First you have to answer the question, "What is DTP and what is it used
for?"
The Cisco answer: Dynamic Trunking Protocol (DTP) for negotiating trunking
on a link between two devices and for negotiating the type of trunking
encapsulation (802.1Q or ISL) to be used
That being said. You must specify the type of encapsulation you want to use
on the trunk link (dot1q or isl). Then, you must issue the command
switchport mode trunk. This sets the port to a trunk unconditionally and it
will no longer use DTP frames to try to negotiate becoming a trunk nor will
it listen for DTP frames.
