Overview of the Gigabit
Ethernet Modules
The Intel® NetStructure™ 6000 switch has two Gigabit Ethernet
modules. One is a 1000Base-SX card and the other is a 1000Base-
LX/1000Base-SX card.
1000Base-SX Module
The chassis can house up to four 1000SX Gigabit Ethernet modules.
Each Gigabit Ethernet module has eight switched ports.
Each port operates in full-duplex mode only, and can be put in auto-
negotiation mode for flow control parameters.
Setting Auto-negotiation
Auto-negotiation makes it possible for devices to exchange
information about their abilities over a link segment. This function
allows the devices at both ends of a link segment to advertise abilities
and acknowledge receipt and understanding of the common modes of
operation that both devices share.
The default setting for the switch has auto-negotiation enabled on all
of the ports.
1
Type show link autoneg port_number to display the auto-nego-
tiation parameters for a link.
2
Type the privileged set link port_number noautoneg command
to disable auto-negotiation on a port.
The Gigabit Ethernet module supports full-duplex mode only.
Note If auto-negotiation is not enabled for a remote partner of a
6000 switch port and another Gigabit Ethernet device, auto-
negotiation must be disabled.
Only devices configured for full-duplex mode may send pause
frames. Pause frames provide flow control over full-duplex links.

Intel® NetStructure™ 6000 Switch Modules User Guide
Overview of the Fast Ethernet
Modules
The Intel® NetStructure™ 6000 switch has two Fast Ethernet
modules. One is a 100Base-TX card which can upgrade your Ethernet
network to Fast Ethernet by supporting both 10Mbps and 100Mbps
on each switched port.
The other module is a 100Base-FX card which can directly upgrade
your Ethernet network to 100Mbps.
10/100 Ethernet Module
This module is a 24-port 100Base-TX Ethernet card. It supports full-
and half-duplex 10 and 100Mbps data transfer and auto-negotiation.
Setting Auto-negotiation
Auto-negotiation allows each end of a link to query the other to
determine a compatible mode of operation. For example, if both links
support full-duplex operation, then the switch can determine this
mode.
When a link becomes active, the switch determines the highest
throughput mode of operation between the two devices.
The Control Process (CP) software also includes commands that
allow the speed and duplex of the ports to be manually set.
Note The default setting is “autoneg 100 10 full half.” The link
uses autonegotiation to choose the best mode. This is usu-
ally the best setting unless the remote partner is not working
properly. When the remote partner is not capable of autone-
gotiation, the port autosenses the speed and defaults to half
duplex.
Type the privileged set link port_number options command, where
port_number is one of the global ports on the chassis and options are
autoneg or noautoneg, 10, 100, half or full.
Example
Intel Switch>#>set link 6 100 FULL no autoneg

The link configuration is stored in non-volatile memory. This allows
the current setting to be restored upon the next reset.
The set link port_number defaults command restores the factory
default link settings to the switch.
Type the non-privileged show link port_number command to display
the current state of the link.

The switch’s default link
connects with any
properly operating link.
However, a port can be
configured to link without
auto-negotiation into one
of several configurations.
If plugged into a port that
has been configured
differently, the link might
not connect or might not
work properly. For
example, a full-duplex
port connected to a half-
duplex port might have
many frame errors.The
best solution is to use the
ports in auto-negotiation
mode with properly
functioning devices
plugged into them.
