B.3 How the AP Receives its Adaptive Configuration
An AAP does not require a separate "local" or "running" configuration. Once enabled as an AAP, the AP obtains its
configuration from the switch. If the AP’s WAN link fails, it continues to operate using the last valid configuration until its
link is re-established and a new configuration is pushed down from the switch. There is no separate file-based
configuration stored on the switch.
Only WLAN, VLAN extension and radio configuration items are defined for the AAP by its connected switch. None of the
other Access Point configuration items (RADIUS, DHCP, NAT, Firewall, etc.) are configurable from the connected switch.
After the AP downloads a configuration file from the switch, it obtains the version number of the image it should be
running. The switch does not have the capacity to hold the Access Point’s firmware image and configuration. The Access
Point image must be downloaded using a means outside the switch. If there is still an image version mismatch between
what the switch expects and what the AAP is running, the switch will deny adoption.
B.3.1 Adaptive AP Pre-requisites
Converting an AP-5131 or AP-7131 model Access Point into an AAP requires:
• A version 2.0 or higher firmware running on the Access Point.
• A Motorola Solutions RF Switch running firmware version 3.1 or later.
• The appropriate switch licenses providing AAP functionality on the switch.
• The correct password to authenticate and connect the adaptive to the switch.
B.3.2 Configuring the Adaptive AP for Adoption by the Switch
1. An AAP needs to find and connect to the switch. To ensure this connection:
• Configure the switch’s IP address on the AAP
• Provide the switch IP address using DHCP option 189 on a DHCP server. The IP address is a comma delimited string
of IP addresses. For example "157.235.94.91, 10.10.10.19". There can be a maximum of 12 IP addresses.
• Configure the switch’s FQDN on the AAP. The AAP can use this to resolve the IP address of the switch.
2. Use the switch’s secret password on the AAP for the switch to authenticate it.
To avoid a lengthy broken connection with the switch, Motorola Solutions recommends generating an SNMP trap when the
AAP loses adoption with the switch.
B.3.3 Configuring the Switch for Adaptive AP Adoption
The tasks described below are configured on a Motorola Solutions RF switch. For information on configuring the switch
for AAP support, see
http://www.motorola.com/Business/US-EN/Support . To adopt an AAP on a switch:
1. Ensure enough licenses are available on the switch to adopt the required number of AAPs.
2. As soon as the AAP displays in the adopted list:
Adjust each AAP’s radio configuration as required. This includes WLAN-radio mappings and radio parameters.
NOTE When configuring wireless settings for Adaptive APs all configuration must be
done through the switch and not from the AP management console. Making
changes directly in the AP management console can lead to unstable operation of
the Adaptive AP.
NOTE

described above, see
