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:

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.
