4.3.4Hardware Requirements

The various teaming modes described in this manual place certain restrictions on the networking equipment used to connect clients to teamed systems. Each type of network interconnect technology has an effect on teaming as described in the following sections.

•Repeater Hub

A Repeater Hub allows a network administrator to extend an Ethernet network beyond the limits of an individual segment. The repeater regenerates the input signal received on one port onto all other connected ports, forming a single collision domain. This means that when a station attached to a repeater sends an Ethernet frame to another station, every station within the same collision domain will also receive that message. If two stations begin transmitting at the same time, a collision occurs, and each transmitting station must retransmit its data after waiting a short (random) amount of time.

The use of a repeater requires that each station participating within the collision domain operate in half-duplex mode. Although half-duplex mode is supported for Gigabit Ethernet adapters in the IEEE 802.3 specification, half-duplex mode is not supported by the majority of Gigabit Ethernet adapter manufacturers. Therefore, half-duplex mode will not be considered here.

Teaming across hubs is supported for troubleshooting purposes (such as connecting a network analyzer) for SLB teams only.

•Switching Hub

Unlike a repeater hub, a switching hub (or more simply a switch) allows an Ethernet network to be broken into multiple collision domains. The switch is responsible for forwarding Ethernet packets between hosts based solely on Ethernet MAC addresses. A physical network adapter that is attached to a switch may operate in half-duplex or full-duplex mode.

To support Generic Trunking and 802.3ad Link Aggregation, a switch must specifically support such functionality. If the switch does not support these protocols, it may still be used for Smart Load Balancing.
