Service Manual

• For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet then the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port information.
• For the Management interface on the RPM, enter the keyword ManagementEthernet then the slot/port information.
The slot range is from 0 to 1. The port range is 0.
2. Enable the interface.
INTERFACE mode
no shutdown
To conrm 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 each unit of the S3048–ON
The interface provides dedicated management access to the system.
Stack—unit interfaces support Layer 2 and Layer 3 trac 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 trac. 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 Conguration. 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.
Conguration Task List for Physical Interfaces
By default, all interfaces are operationally disabled and trac does not pass through them.
The following section includes information about optional congurations for physical interfaces:
• Overview of Layer Modes
• Conguring Layer 2 (Data Link) Mode
• Conguring 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.
