Configuring Co-located APs in Load Balance Groups
You can configure APs that are co-located in an open area, such as a classroom, a conference hall,
or an entrance lobby, to act as a load balance group. Load balancing distributes clients across the
co-located APs that are members of the load balance group. The co-located APs should provide
the same SSID, have Line-of-Sight (LoS) between each other, and be deployed on multiple
channels with overlapping coverage.
WLC Search List Click one of the following:
• Clear search list — Click to clear previously assigned
SCALANCE IWLAN Controllers that were configured to control
this Wireless AP.
• Re-configure search list — Click to assign SCALANCE
IWLAN Controllers to control this Wireless AP. This causes the
Add box to become available.
Add box Enter the IP address of the SCALANCE IWLAN Controller that will
control this Wireless AP.
This box is available only if you selected Re-configure search
list when configuring the search list.
Click the Add button to add the IP address to the list. Repeat to
add additional SCALANCE IWLAN Controllers. The maximum is
three SCALANCE IWLAN Controllers.
Click Up and Down to modify the order of the SCALANCE IWLAN
Controllers.
The Wireless AP is successful when it finds a SCALANCE IWLAN
Controller that will allow it to register.
This feature allows the Wireless AP to bypass the discovery
process. If the WLC Search List is not populated, the Wireless
AP will use SLP unicast/multicast, DNS, or DHCP vendor option
43 to discover a SCALANCE IWLAN Controller. For the initial
Wireless AP deployment, it is necessary to use one of the
described options in “Discovery and Registration Overview” on
page 3-9.
Tunnel MTU Enter a static MTU value, from 600 to 1500. If the Siemens
wireless software cannot discover the MTU size, it enforces the
static MTU size. Set the MTU size to allow the source to reduce
the packet size and avoid the need to fragment data packets in the
tunnel.
WLAN Assignments
WLAN Assignments From the drop-down list, click one of the following:
• Clear WLAN list — Click to clear previously assigned WLAN
services of the Wireless APs.
• Re-configure WLAN list — Click to assign WLAN services to
the Wireless APs.
In the Radio 1 and Radio 2 columns, select the Wireless AP
radios that you want to assign for each WLAN service.
Save Click to save your changes.
