Configure this load balancing metric when the objective of load balancing is to distribute
traffic load evenly across all controllers deployed in the domain. Note that this metric
achieves only a partial coverage redundancy since it allocates the APs or WSPs to
different controllers in the order in which the APs join the mobility domain. Full coverage
redundancy can be achieved only using manual configuration.

Location based:
This metric assigns APs or WSPs based on configured location information for APs/WSPs
and controllers. You can segment a physical environment of the enterprise into campus
(C), building (B), floor (F) and sector (S). You can then specify the location of APs or
WSPs in the mobility domain in terms of C-B-F-S parameters in the domain AP or WSP
database. Each location is an 8 byte ASCII string and the level of granularity increases
from C—>B—>F—>S. The location specification starts from lowest granularity level.
When a granularity level is not specified, it means that the level is not included in the
location specification. The location based metric uses a best location granularity match
between the AP or WSP location and WC location for assignment of AP or WSP to WC.
When multiple WCs match the AP or WSP location, the least loaded WC is selected for
assignment.
The WC location is a mobility domain configuration that must be synchronized with all
domain member WC devices using the
config-sync
action. AP or WSP location is
configured in the domain AP/WSP database for each AP/WSP and must also be
synchronized with all domain member WC devices.

Configuring load balancing
Use the commands in this procedure to configure load balancing for a controller, Access Point
(AP) or Wireless Switching Point (WSP).
Procedure
1. Enter the domain load balance configuration mode of the controller:
WCP8180#conf t
WCP8180(config)#wireless
WCP8180(config-wireless)#domain load-balance
WCP8180(config-wireless-lb)#
CLI Reference:
