Switch Trunking

When connecting multiple switches together, even with using just one VLAN, do you still need to configure trunking? I was under the impression the switch would learn that the other was a switch simply via CAM tables.

    It depends on what model of switch you have. Some come out of the box set to dynamic desirable and will form a trunk with another switch with the same setting and or dynamic auto. I believe the newer 2960's come out of the box set to dynamic auto and will not trunk with each other unless the settings are changed.

    If there's only one Vlan on the switch which is by default Vlan1 (native vlan), you don't need to configure trunk links between the switches...

    In addition to Rinoel, trunks pass multi-vlan traffic. If you don't have more than one vlan, you don't need a trunk.

    Thank you all for the information. I was sort of thinking that a trunk was not necessary for the same reasons. Thank you all, again!
