Configuration Task List For Physical Interfaces; Overview Of Layer Modes - Dell S4820T Configuration Manual

Stack—unit interfaces support Layer 2 and Layer 3 traffic over the 10/100/1000 and 10-Gigabit Ethernet
interfaces. Synchronous optical network technologies interfaces with point-to-point protocol (PPP)
encapsulation support Layer 3 traffic. These interfaces can also become part of virtual interfaces such as
virtual local area networks (VLANs) or port channels.
For more information about VLANs, refer to
refer to Port Channel Interfaces.
Dell Networking OS Behavior: The system uses a single MAC address for all physical interfaces.

Overview of Layer Modes
On all systems running Dell Networking OS, 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.
