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.
1Type show link autoneg port_number to display the auto-nego- tiation parameters for a link.
2Type 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.
