Prioritizing AP heartbeats
To prioritize AP heartbeats using the WebUI:
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, then AP system profile. The configuration settings are displayed in Profile Details.
4. Under Profile Details:
a. In the Heartbeat DSCP field, enter a value greater than zero.
b. Click Apply.
To prioritize AP heartbeats using the command-line interface, access the CLI in config mode and issue the
following command:
ap system-profile <profile>
heartbeat-dscp <number>
AP Redundancy
In conjunction with the controller redundancy features described in Chapter 24, “VRRP” 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 Chapter 7,
“Remote Access Points” .
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:
 You have not configured the LMS or backup LMS IP addresses
 Default values unless otherwise noted.
In 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 Table 22 on page 128.
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.
In the CLI
ap system-profile <profile>
lms-ip <ipaddr>
bkup-lms-ip <ipaddr>
