Overview of Layer Modes
On all systems running FTOS, you can place physical interfaces, port channels, and VLANs in Layer 2
mode or Layer 3 mode. By default, VLANs are in Layer 2 mode.

Configure Layer 2 (Data Link) Mode
To enable Layer 2 data transmissions through an individual interface, use the
INTERFACE mode. You cannot configure switching or Layer 2 protocols, such as the spanning tree
protocol (STP), on an interface unless the interface has been set to Layer 2 mode.
