Jul 29, 2007 · When you remove VLAN 1 from a trunk port, the interface continues to send and receive management traffic, for example, Cisco Discovery Protocol (CDP), Port Aggregation Protocol (PAgP), Link Aggregation Control Protocol (LACP), Dynamic Trunking Protocol (DTP), and VLAN Trunking Protocol (VTP) in VLAN 1.

Dynamic Trunking Protocol (3.2.3) The Dynamic Trunking Protocol (DTP) is used to negotiate forming a trunk between two Cisco devices. DTP causes increased traffic, and is enabled by default, but may be disabled. Introduction to DTP (3.2.3.1) Ethernet trunk interfaces support …

DTP frames are NOT sent when a port is configured as Dynamic Auto, Non-negotiate or Access. So, even if a port is in Dynamic Auto and doesn’t send DTP frames, it is still considered Negotiation ON because it can be affected by the DTP frames it receives. HTH!
https://en.wikipedia.org/wiki/Dynamic_Trunking_Protocol
The Dynamic Trunking Protocol (DTP) is a proprietary networking protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN-aware switches, and for negotiating the type of trunking encapsulation to be used. It works on Layer 2 of the OSI model.

Dynamic Trunking Protocol (DTP) can also be used for negotiating the encapsulation type of either IEEE 802.1Q or Cisco ISL (Inter-Switch Link). Please note that Cisco ISL (Inter-Switch Link) is no more a widely accepted trunking standard. Many of the recent Cisco switches only support IEEE 802.1Q trunking standard. Dynamic Trunking Protocol ...

A Non-Cisco network device or Switch from other vendors do not support DTP. DTP manages trunk negotiation only if the port on the neighbor switch is configured in a trunk mode that supports DTP. Switch trunk interfaces support different trunking modes. An interface can …

In this tutorial we’ll take a look at DTP (Dynamic Trunking Protocol) negotiation. DTP is normally used on Cisco IOS switches to negotiate if the interface should become an access port or trunk. By default DTP is enabled and the interfaces of your switches will be in “dynamic auto” or “dynamic desirable” mode.
