196 Configuring RF load balancing for APs
NN47250-500 (320657-F Version 02.01)
• Assigning radios to load balancing groups
• Specifying band preference for RF load balancing
• Setting strictness for RF load balancing
• Exempting an SSID from RF load balancing
Disabling or re-enabling RF load balancing
RF load balancing is enabled by default globally on the WSS switch and for individual radios. To disable or re-enable
RF load balancing globally, use the following command:
set load-balancing mode {enable | disable}
To disable or re-enable RF load balancing for an individual radio, use the following command:
set ap ap-num radio radio-num load-balancing {enable | disable}
If RF load balancing has been enabled or disabled for a specific AP radio, then the setting for the individual radio takes
precedence over the global setting.
Assigning radios to load balancing groups
Assigning radios to specific load balancing groups is optional. When configured, WSS considers the radios to have
exactly overlapping coverage areas, rather than using signal strength calculations to determine their overlapping
coverage. WSS attempts to distribute client sessions across radios in the load balancing group evenly. A radio can be
assigned to only one group.
To assign radios to load balancing groups, use the following command:
set ap ap-num radio radio-num load-balancing group name [rebalance]
Use the rebalance parameter to configure the radio to disassociate its client sessions and rebalance them whenever a
new radio is added to the load balancing group.
To remove a radio from its specified load balancing group, use the following command:
clear ap ap-num radio radio-num load-balancing group
Specifying band preference for RF load balancing
If a client supports both the 802.11a and 802.11b/g bands, you can configure WSS to steer the client to a less-busy radio
on an AP for the purpose of load balancing. A global “band-preference” option controls the degree of concealment that
an AP with two radios attempts to hide one of the radios from a client with the purpose of steering the client to the other
radio.
To cause clients that support both the 802.11a and 802.11b/g radio bands to be steered to a specific radio on the AP for
the purpose of load balancing, use the following command:
set band-preference {none | 11bg | 11a}
