Answered Question

Confused.... Is "dynamic auto" or "dynamic desirable" the default for switches?

I have this problem too.

DTP Modes:

switchport mode dynamic desirable - This command 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. This is the default mode for all Ethernet interfaces. If the neighboring interface is set to the access or non-negotiate mode, the link will become a non-trunking link.

switchport mode dynamic auto - This command makes the interface willing to convert the link to a trunk link if the neighboring interface is set to trunk or desirable mode. Otherwise, the link will become a non-trunking link.
