Physical Interfaces

The Management Ethernet interface is a single RJ-45 Fast Ethernet port on a switch.
The interface provides dedicated management access to the system.
Stack-unit interfaces support Layer 2 and Layer 3 traffic over the 10-Gigabit Ethernet and 40-Gigabit Ethernet, 25–Gigabit Ethernet,
40–Gigabit Ethernet, 50–Gigabit Ethernet, and 100–Gigabit Ethernet interfaces. 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
Interfaces.
Dell Networking OS Behavior: The system uses a single MAC address for all physical interfaces.

Configuration Task List for Physical Interfaces

By default, all interfaces are operationally disabled and traffic does not pass through them.
The following section includes information about optional configurations for physical interfaces:

Overview of Layer Modes

• Configuring Layer 2 (Data Link) Mode
• Configuring Layer 2 (Interface) Mode
• Management Interfaces
• Auto-Negotiation on Ethernet Interfaces
• Adjusting the Keepalive Timer
• Clearing Interface Counters
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.
