Teaming Options
The onboard PRO/100+ ethernet controller provides several options for
increasing throughput and fault tolerance when running Windows NT 4.0
or NetWare 4.1x or newer:
•
Adapter Fault Tolerance (AFT) - provides automatic redundancy
for your controller. If the primary controller fails, the secondary
takes over.
•
Adaptive Load Balancing (ALB) - creates a team of two, three, or
four adapters to increase transmission throughput. Also includes
the AFT option. Works with any 100BASE-TX switch.
•
Fast EtherChannel (FEC) - creates a team of two to four adapters to
increase transmission and reception throughput. Also includes the
AFT option. Requires a Cisco switch with FEC capability.
To set up an option, go to the appropriate section in the pages that follow.
General Configuration Notes
•
Adapter Teaming options are supported by Windows NT versions
4.0 and later .
•
Adapter Teaming options require NT 4.0 with Service Pack 3.0
and the NDIS driver hotfix from Microsoft. See the Late Breaking
News for details.
Setting Up Adapter Fault Tolerance Only
Adapter Fault Tolerance provides the safety of an additional backup link
between the server and hub or switch. In the case of hub or switch port,
cable, or controller failure, you can maintain uninterrupted network
performance.
Adapter Fault Tolerance is implemented with a primary controller and a
backup, or secondary, adapter. During normal operation, the backup
adapter will have transmit disabled. If the link to the primary controller
fails, the link to the secondary adapter automatically takes over.
Note:
One or more Intel PRO/
100+ PCI ethernet adapters
may be added to the
system. These adapters
work in conjunction with the
onboard Intel PRO/100+
ethernet controller to
achieve the enhancements
sdescribed in this section.
The onboard ethernet
controller is refered to as
the primary controller
throughout. When the
statement refers to either
the onboard controller or an
adapter, the term adapter is
used.
Note:
Use this procedure to set
up AFT only. If setting up
ALB or FEC, use the
procedures in the next
sections. The AFT feature
runs automatically when
you enable ALB or FEC.
