Load Balance

Load balance is a protocol-specific scheme. The levels of support for IP, IPX, and other
protocols are listed below.
Protocol
IP
IPX
Other protocols
*Only outbound load-balancing for IPX (on NetWare only).
**For 3Com NICs.
Load balance mode works with all Ethernet switches without configuring the switch ports
to any special trunking mode. Only IP traffic will be load-balanced in both inbound and
outbound directions. IPX traffic will be load-balanced in the outbound direction only.
Other protocol packets will be sent and received through one primary NIC only. Failover
for non-IP traffic is supported using 3Com,Broadcom,Alteon, and Intel NICs. The generic
trunking mode requires the Ethernet switch to support some form of port trunking mode
(for example, Cisco Systems Gigabit EtherChannel or other switch vendors' link
aggregation mode). This mode is protocol-independent and all traffic should be load-
balanced and fault-tolerant.

Advanced Server Features for Windows 2000

The following options are supported under Windows 2000 Server operating systems
(Server, Advanced Server, Datacenter Server). See "Windows 2000 Driver Setup" on
page 25 for additional information.
