Adding NICs to a Group
1 Click the Load Balance/RSL tab.
2 In the Load Balance/RSL window:
Select a group from the Load Balancing/RSL Groups
list.
Select a NIC from the Network Interface Cards list.
3 Click Add NIC.
The NIC appears as part of the group in the Load
Balancing/RSL list box.
If you click Add NIC repeatedly, NICs are added to the
group in the order that they are listed after the first NIC
you selected.
Specifying a Dedicated IP Address
Bidirectional load balancing requires that you specify a
dedicated IP address for the load balancing group. This
address specifies a Network ID and a Host ID, and it must
be unique (not used elsewhere on the network). For
example:
You can specify the dedicated IP address in the Create
Group or Group Properties dialog boxes. You cannot
specify the bytes for the Network ID; they are fixed. Specify
the bytes for the Host ID for various classes of subnets
as follows:
Byte 1 Byte 2 Byte 3 Byte 4
Class A Network ID Host ID
125 24 1 253
Class B Network ID Host ID
139 25 2 253
Class C Network ID Host ID
193 26 3 253
Class Byte 1 Specify only bytes
A 126 2, 3, and 4 (the three rightmost boxes).
B 128 - 191 3 and 4 (the two rightmost boxes).
C 192 - 223 4 (the rightmost box).
