switchport mode access
Puts the interface (access port) into permanent nontrunking mode and negotiates
to convert the link into a nontrunk link. The interface becomes a nontrunk
interface regardless of whether or not the neighboring interface is a trunk
interface.
switchport mode dynamic auto
Makes the interface able to convert the link to a trunk link. The interface
becomes a trunk interface if the neighboring interface is set to trunk or
desirable mode. The default switchport mode for all Ethernet interfaces is
dynamic auto.
switchport mode dynamic desirable
Makes the interface actively attempt to convert the link to a trunk link. The
interface becomes a trunk interface if the neighboring interface is set to
trunk, desirable, or auto mode.
switchport mode trunk
Puts the interface into permanent trunking mode and negotiates to convert the
neighboring link into a trunk link. The interface becomes a trunk interface
even if the neighboring interface is not a trunk interface.
switchport nonegotiate
Prevents the interface from generating DTP frames. You can use this command
only when the interface switchport mode is access or trunk. You must manually
configure the neighboring interface as a trunk interface to establish a trunk
link.

Sorry Jared,
Correct me if I am wrong but it is not like switchport mode access will
disable DTP and will never form a trunk, regardless of configuration on the
other end of the link. And switchport nonegotiate will disable DTP and will
form a turnk if both the ends are configured with switchport mode trunk.
Thanks,
Haresh

Nope. “switchport nonegotiate” disables DTP.

Hello Group !!!
Just a quick question ,
will this command disable DTP switchport mode access
I know switchport nonegotiate disables but what if we just specify the above
will it disable DTP
