3 Ethernet interface configuration
Nortel Secure Router 8000 Series
Configuration - LAN Access and MAN Access
3.1 Introduction
This section describes the concepts that you need to know before you configure an Ethernet
interface:
• Introduction to Ethernet interfaces
• Classification of Ethernet interfaces
3.1.1 Introduction to Ethernet interfaces
Because it is flexible, simple, and easy to deploy, the Ethernet is an important form of local
area network (LAN) networking technology.
3.1.2 Classification of Ethernet interfaces
At present, the LAN interfaces supported by the Secure Router 8000 Series are the Ethernet
interfaces, including the traditional Ethernet electrical interface, Fast Ethernet interface, and
Gigabit Ethernet interface. The Secure Router 8000 Series supports the Layer 2 features of the
Ethernet interface. The following list describes the three Ethernet interfaces:
• The traditional Ethernet interface complies with 10Base-T specifications and can work at
the speed of 10 megabits per second (Mbit/s).
• The Fast Ethernet (FE) interface complies with 100Base-TX specifications and is
compatible with 10Base-T specifications.
• The Gigabit Ethernet (GE) interface complies with 1000Base-TX specifications and is
compatible with 10Base-T and 100Base-TX specifications.
Ethernet electrical interfaces can work in either full-duplex mode or half-duplex mode, and
they support autonegotiation. In autonegotiation mode, they negotiate with other network
devices for the most suitable working mode and speed, which simplifies system configuration
and management.
03 NOTE
• This chapter explains the configuration of the FE and GE interfaces. The configuration of traditional
Ethernet interface is simple and similar to that of the FE interface.
• Ethernet subinterfaces are applied in a Virtual Local Area Network (VLAN). For information about
Ethernet subinterfaces, see Chapter 4, “VLAN Configuration.”
3.2 Configuring Ethernet interfaces
3.2.1 Establishing the configuration task
Applicable environment
To configure the Ethernet to transmit data packets, you must configure Ethernet interfaces.
When you configure an Ethernet interface, you must assign an IP address to it. For other
parameters, you can use default values. If you have to change the values, keep them consistent
with the peer device.
