What is the operational state when SW1 G0/0 is dynamic desirable and SW2 G0/0 is also dynamic auto?

When SW1 G0/0 is configured as dynamic desirable and SW2 G0/0 is configured as dynamic auto, the operational state is a trunk. This is because the dynamic desirable configuration on SW1 actively seeks to form a trunk and negotiate the connection, while the dynamic auto configuration on SW2 is set to respond to trunking requests automatically. When both switches support dynamic trunking protocol (DTP), the interaction between these two configurations results in the formation of a trunk link.

In this context, SW1 is actively trying to establish a trunk, and SW2 is passively willing to accept that request, so they will successfully negotiate a trunk link if both have compatible settings. This behavior is fundamental to how DTP operates: the dynamic desirable state allows a switch to initiate trunking, whereas dynamic auto allows a switch to accept trunking requests from others without actively trying to initiate trunking itself.
