Configuring Ethernet interfaces

In this chapter, "MSR1000" refers to MSR1002-4. "MSR2000" refers to MSR2003, MSR2004-24,
MSR2004-48. "MSR3000" collectively refers to MSR3012, MSR3024, MSR3044, MSR3064.
"MSR4000" collectively refers to MSR4060 and MSR4080.
Your device supports the following types of Ethernet interfaces:
Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer (Layer 2)
•
to switch packets.
Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer (Layer 3) to
•
route packets. You can assign an IP address to a Layer 3 Ethernet interface.
Layer-configurable Ethernet interfaces—Physical Ethernet interfaces that can be configured to
•
operate in bridge mode as Layer 2 Ethernet interfaces or in route-mode as Layer 3 Ethernet
interfaces.
Layer 3 Ethernet subinterfaces—Logical interfaces operating at the network layer. You can assign
•
an IP address to a Layer 3 Ethernet subinterface. By creating subinterfaces on a Layer 3 Ethernet
interface, you enable the interface to carry packets for multiple VLANs. For how a Layer 3 Ethernet
subinterface sends and receives VLAN-tagged packets, see Layer 2—LAN Switching Configuration
Guide.

Configuring common Ethernet interface settings

This section describes the settings common to Layer 2 and Layer 3 Ethernet interfaces or subinterfaces.
For more information about the settings specific to Layer 2 and Layer 3 Ethernet interfaces or
subinterfaces, see

Configuring a combo interface

A combo interface is a logical interface that physically comprises one fiber port and one copper port.
The two ports share one forwarding channel and one interface view, so they cannot work simultaneously.
When you activate one port, the other port is automatically disabled. In the interface view, you can
activate the fiber or copper combo port, and configure other port attributes such as the interface rate and
duplex mode.
Configuration prerequisites
Before you configure combo interfaces, complete the following tasks:
Determine the combo interfaces on your device and identify the two physical interfaces that
•
compose each combo interface according to the marks on the device panel.
Use the display interface command to determine which port (fiber or copper) of the combo
•
interface is active. If the current port is the copper port, the output includes "Media type is twisted
pair, Port hardware type is 1000_BASE_T." If the current port is the fiber port, the output does not
include this information. You can also use the display this command in the view of the combo
interface to view the combo interface configuration. If the combo enable fiber command exists, the
fiber port is active. If the command does not exist, the copper port is active.
