AT-2701 Series Fast Ethernet Adapter Installation Guide

Configuring an Ethernet Interface on Linux Systems

Configuring an Ethernet Interface on Ubuntu

This section provides how to set the speed and duplex mode to the Ethernet interfaces of AT-2701 series fiber optic adapters. The following is the general instructions for Ubuntu and Red Hat Linux distributions. For other distributions of Linux, consult documentation for your systems.

To configure Ethernet interfaces of AT-2701 series fiber optic adapters:

1.Verify that the ethtool utility is installed on your system by entering the following command:

ethtool

If the ethtool utility is not installed on your system, the system shows an error message. If the ethtool utility is installed, skip step 2.

2.If your system does not have the ethtool utility installed, Install it by entering the following command:

sudo apt-get install ethtool

3.Obtain the name of the Ethernet interface for the AT-2701 series adapter, such as eth0 and eth1, by entering the following command:

ifconfig

You have one Ethernet interface per AT-2701 series adapter card.

Note

To identify the Ethernet interface of the AT-2701 series adapter, match the MAC address of the ethN interface that the ifconfig command displays with one on the label of the shipping package.

4.Edit /etc/network/interfaces file to disable Auto-negotiation and set the speed and duplex mode by inserting the following statements:

auto ethx

iface ethx inet dhcp

pre-up/sbin/ethtool -s ethx speed 100 duplex full autoneg off

Note

Replace "ethx" with the name of the Ethernet interface that you obtained in step 3. "ethx" appears three times in the statement.

5.Repeat step 4 for all of the Ethernet interfaces of AT-2701 series adapters on your system.
