Adding NICs to a Group

1Click the Load Balance/RSL tab.

2In the Load Balance/RSL window:

•Select a group from the Load Balancing/RSL Groups list.

•Select a NIC from the Network Interface Cards list.

3Click 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:

 

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

 

 

 

 

 

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:

Class

Byte 1

Specify only bytes

A

2, 3, and 4 (the three rightmost boxes).

B128 - 191 3 and 4 (the two rightmost boxes).
