ALANCING FOR
MAP
S
MSS balances the client load by adjusting how MAPs are perceived by
clients. As the relative capacity of a MAP handling new clients falls
relative to other MAPs in the area, MSS makes the MAP more difficult for
potential new clients to detect, which causes a client to associate with a
MAP with more capacity. Note that by default MSS prevents clients from
associating with a MAP only if there are other MAPs with available
capacity in the area; clients are not prevented from associating with a
MAP if it is the only one available.
You can optionally place MAP radios into load balancing groups. When
two or more MAP radios are placed in the same load balancing group,
MSS assumes that they have exactly the same coverage area, and
attempts to distribute the client load across them equally. The MAP radios
do not have to be on the same WX switch. A balanced set of MAP radios
can span multiple WX switches in a Mobility Domain.
Configuring RF
Load Balancing
This section describes the following configuration tasks:
„
Disabling or re-enabling RF load balancing
„
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 WX switch and for
individual radios. You can disable or enable it globally by using the
following command:
set load-balancing mode { enable | disable }
To disable or enable RF load balancing for an individual radio, use the
following command:
set ap apnumber radio radio-num load-balancing { enable |
disable }
If RF load balancing has been enabled or disabled for a specific MAP
radio, then the setting for the individual radio takes precedence over the
global setting.
