AT-2711 Series Fast Ethernet Network Adapters
Linux Configurations
This document describes how to configure the Ethernet Interface for AT-2711 series adapters in
Linux systems. It contains the following topics:
“Overview,”
“Configuring Ubuntu,”
“Configuring Red Hat” on page 3
Overview
The AT-2711 series adapters use a Linux inbox driver to operate. A driver
supplied with an operating system is called an inbox driver. Current Linux systems
come with the inbox driver that the AT-2711 series adapters need.
Since the driver software for the AT-2711 series adapters has already been in
place, you do not need to install it; however, the speed and duplex mode for the
fiber optic port are not automatically negotiated. You must disable Autonegotiation and sets these properties for the AT-2711 series fiber optic port
manually.
In addition, you must set the same property values on the port interfaces of the
connected switch.
The following is the general instructions of how to set the speed and duplex mode
to the Ethernet interfaces for Ubuntu and Red Hat Linux distributions. For other
distributions of Linux, consult documentation for your systems.
Configuring Ubuntu
To configure Ethernet interfaces of AT-2711 series fiber optic adapters:
1. Verify that the ethtool utility is installed on your system by entering the fol-
lowing 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-2711 series adapter, such
as eth0 and eth1, by entering the following command:
ifconfig
You have one Ethernet interface per AT-2711 series adapter card.
To identify the Ethernet interface of the AT-2711 series adapter, match the
MAC address of the eth
N
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 eth
iface ethx inet dhcp
pre-up/sbin/ethtool -s eth
x
x
speed 100 duplex full autoneg off
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-2711 series adapters on
your system.
6. Save the /etc/network/interfaces file.
7. Reboot your Linux system.
8. Verify that your AT-2711 series adapter is running 100 Mbps in the full-duplex
mode by entering the following command:
ethtool eth
x
The command output should display:
Advertised Auto-Negotiation is No
Speed is 100
Duplex mode is Full
9. Repeat step 8 for all of the Ethernet interfaces of AT-2711 series adapters on
your system.
