How Availability Affects Load Balancing

All radios assigned to a load group must belong to APs that are all controlled by the same

SCALANCE IWLAN Controller. If you have enabled availability configuration of a load group is

only possible from the home controller where the load group was created. Load balancing will

continue to operate if member APs fail over to the foreign controller as long as the WLAN service

assignment remains the same.

To ensure that load balancing works properly in availability, you should enable synchronization

of the system configuration and the WLAN services used by the load group when you configure

availability. If you do not enable synchronization, the radios on any AP that fails over may be

removed from their assigned load groups. For more information, see “Configuring Availability

Using the Availability Wizard” on page 12-3.

If you have not configured synchronization, in a failover situation you will be able to change the

load balance group’s WLAN service assignment from the VNS Configuration screens and the

Wireless AP's WLAN Assignment screens on the foreign controller.

Note:

If you have configured synchronization, you cannot change the WLAN assignments from the foreign

controller.

WLAN Assignment tab

WLAN Name Click the checkbox of the one or more WLAN services that you

want to assign to all member radios of the load balance group.

You can select up to the radio limit of eight VNSs.

When you assign a radio to a load group, WLAN service

assignment can only be done from the WLAN Assignment tab on

the Wireless AP Load Groups screen. On all other WLAN

Assignment tabs associated with the member AP radios, the

radio checkbox associated with the member AP radios will be

grayed out. When you remove a radio from a load group, the load

group’s WLAN service will remain assigned to the radio, but you

can now assign a different WLAN service to the radio.

Add Load Group Window
