Enabling a Physical InterfaceAfter determining the type of physical interfaces available, to enable and configure the interfaces, enter INTERFACE mode by using theinterface interface command.1 Enter the keyword interface then the type of interface and slot/port[/subport] information.CONFIGURATION modeinterface interface• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.2 Enable the interface.INTERFACE modeno shutdownTo confirm that the interface is enabled, use the show config command in INTERFACE mode. To leave INTERFACE mode, use theexit command or end command. You cannot delete a physical interface.Physical InterfacesThe 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 interfaces. These interfacescan 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 Networking OS Behavior: The system uses a single MAC address for all physical interfaces.Configuration Task List for Physical InterfacesBy 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 CountersOverview of Layer ModesOn 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.396 Interfaces
