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

.
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
