In the CLI
Use the following commands to configure an RTLS server with station message frequency using the CLI:
(host) (config) #ap system-profile default
(host) (AP system profile "default") #rtls-server ip-or-dns <IP or DNS of RTLS server> port
<port> key <key> station-message-frequency <1-3600>
Important Points to Remember
l Sending more frequent reports to the server can improve the accuracy of the location calculation.
l Configuring an AP to send reports more frequently adds additional load in terms of CPU usage.
AP Redundancy
In conjunction with the controller redundancy features described in Increasing Network Uptime Through
Redundancy and VRRP on page 570 the information in this section describes redundancy for APs. Remote APs
also offer redundancy solutions via a backup configuration, backup controller list, and remote AP failback. For
more information relevant to remote APs, see Remote Access Points on page 629.
The AP failback feature allows an AP associated with the backup controller (backup LMS) to fail back to the
primary controller (primary LMS) if it becomes available.
If configured, the AP monitors the primary controller by sending probes every 600 seconds by default. If the
AP successfully contacts the primary controller for the entire hold-down period, it will fail back to the primary
controller. If the AP is unsuccessful, the AP maintains its connection to the backup controller, restarts the LMS
hold-down timer, and continues monitoring the primary controller.
The following example assumes:
l You have not configured the LMS or backup LMS IP addresses
l Default values unless otherwise noted.
Using the WebUI
Follow the procedure below to use the AP system profile to configure a redundant controller. For additional
information on AP system profile settings, see .
1. Navigate to the Configuration > Wireless > AP Configuration page.
2. Select either the AP Group or AP Specific tab. Click Edit for the AP group or AP name.
3. Under Profiles, select AP to display the AP profiles.
4. Select the AP system profile you want to modify.
5. Under Profile Details:
a. At the LMS IP field, enter the primary controller IP address.
b. At the Backup LMS IP field, enter the backup controller IP address.
c. Click (select) LMS Preemption. This is disabled by default.
6. Click Apply.
