Click to expand in new window

AP Load Groups

Field/Button Description
Load Group ID Enter a unique name for the load group. You can create load groups with the same name on different controller; however, the groups are treated as separate groups according to the home controller where the group was originally created.
Type The type of load group is displayed. Options include:
  • Client Balancing - select to perform load balancing based on the number of clients across all APs in the load balance group and only for the WLAN (Wireless Local Area Network) Services assigned to the group.
  • Radio Preference - select to perform band preference steering and enforce load control settings on this load group.
New Click to create a new load group. The Add Load Group window.
Delete Click to delete this load group.
Save Click to save your changes.
Radio Assignment tab - Available for load groups assigned the Client Balancing type.
Select AP Radios From the drop-down menu, select the AP radios that you want to assign to the load group. Options include:
  • All radios
  • Radio 1
  • Radio 2
  • Clear all radios

You can assign a radio to only one load balance group. A radio that is assigned to another load balance group has an asterisk next to it. If you select a radio that has been assigned to another load balance group, the radio is reassigned to the new load balance group.

Note: You can assign each radio of an AP to different load balance groups.
Radio Preference tab - Available for load groups assigned the Radio Preference type
Band Preference Select the Enable checkbox to enable band preference for this load group.

You can apply band preference to a VNS assigned in the load group. Enabling band preference enables you to move an 11a-capable client to an 11a radio to relieve congestion on an 11g radio. A client is considered 11a capable if the AP receives requests on an 11a VNS that already belongs to a load group with band preference enabled. After you configure band preference, if a client tries to re-associate with an 11g radio, it is rejected if the AP determines that the client is 11a capable.
Load Control Select the following parameters for each radio assigned to this load group:
  • Enable: Select this checkbox to enable Radio Load Control (RLC) for individual radios (Radio1 and Radio2) associated with this Load Group.
  • Max. # of Clients: Enter the maximum number of clients for Radio 1 and Radio 2. The default limit is 60. The valid range is: 5 to 60.
  • Strict Limit: Select this checkbox to enable a strict limit on the number of clients allowed on a specific radio, based on the max # of clients allowed. Limits can be enforced separately for radio1 and radio 2.
AP Assignment Select the APs on which you want to enforce the Band Preference and Load Control settings.
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 be done only 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 is grayed out. When you remove a radio from a load group, the load group‘s WLAN service remains assigned to the radio, but you can now assign a different WLAN service to the radio.
