● For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE then the slot/port information.
2. Enable the interface.
INTERFACE mode
no shutdown
To confirm that the interface is enabled, use the show config command in INTERFACE mode. To leave INTERFACE mode,
use the exit command or end command. You cannot delete a physical interface.
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 , 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 Bulk Configuration. For more information on port channels, refer to Port Channel
Interfaces.
Dell EMC 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
● Clearing Interface Counters
Overview of Layer Modes
On all systems running Dell EMC 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.
