Adding a User
Group
You can define a user group and control that group’s access to the load
balanced services. For each request to a service, the Server Load Balancer
determines which user group the client IP address is part of. It then allows
or denies access to the service based on the permissions that were set for
this user group.
The Server Load Balancer has a default user group that is defined as
0.0.0.0 to 255.255.255.255. This user group includes every possible IP
address.
To add a user group, complete the following steps:
1 Click Logical View on the Toolbar.
2 Point to the User Group window border and left-click the mouse button.
3 In the pop-up list, click Add . The Add User Group window appears.
4 Enter a descriptive name, such as
Engineering
, in the Name field.
It is recommended to keep the user group name to a maximum of 20
characters.
5 Repeat Step 4 for every user group you wish to add and click Add .
6 When you have finished entering your user groups, click Done .
Adding IP Address
Ranges to User
Groups
Adding IP address ranges defines those IP addresses that make up your
user group. The Server Load Balancer recognizes any address within these
ranges to be part of the user group.
If a request comes, the Server Load Balancer determines that the client is
part of the Engineering user group and checks the permissions set for
Engineering for the service requested.
To add IP address ranges to your user group, complete the following
steps:
1 Click Logical View on the Toolbar.
2 Point to the User Group window border and left-click the mouse button.
3 In the pop-up list, click Add address range...
4 From the User Group drop-down list box, select Engineering .
5 Enter
192.168.1.100
in the First IP Address field.
6 Enter
192.168.1.150
in the Last IP Address field and click Done .
