What would happen, if I had a port configured with:
switchport access vlan 191
but do not have the command:
switchport mode access?

Hi Friend,
By default all switches layer 2 ports are in dynamic desirable mode so if you do not manually configure it as "switchport mode access" then it will try to from a trunk with remote port which generating DTP frames.
It is always recommended that if you do not want the port to form a trunk manually configure it as an access port.

Hello,
We also enter the command "switchport nonegotiate" on the interface, just to make sure it doesn't try to form a trunk port.

switchport mode access - this puts the interface in access mode only, and it will still generate DTP's to let the other side know.
switchport nonegotiate - whether in trunking or access mode, causes the switch not to generate DTP's.
