Enabling a Physical Interface
After determining the type of physical interfaces available, to enable and congure the interfaces, enter INTERFACE mode by using the
interface interface command.
1 Enter the keyword interface then the type of interface and slot/port[/subport] information.
CONFIGURATION mode
interface 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 mode
no shutdown
To conrm 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 trac over the 10-Gigabit Ethernet and 40-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 Conguration. 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.
Conguration Task List for Physical Interfaces
By default, all interfaces are operationally disabled and trac does not pass through them.
The following section includes information about optional congurations for physical interfaces:
• Overview of Layer Modes
• Conguring Layer 2 (Data Link) Mode
• Conguring 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.
