Auto-Placement Rules for Devices
Auto-Placement rules can be used in two ways: one method is for sensors and the other is for APs and
switches.
• Sensors on page 516
• APs and Switches on page 516
Sensors
Auto-Placement rules for sensors are applied every 20 minutes. If a rule exists, new sensors in the
Unplaced Devices folder are moved into a predefined scope level. This only happens to sensors seen in
your network since the last 20 minute poll. Sensors seen before the last 20 minute poll are excluded.
APs and Switches
Auto-Placement rules for APs and switches are applied when APs or switches are manually added/
imported into a system using the following conditions:
• If a rule exists, the AP or switch is moved into the predetermined scope level.
• If no rule exists, the AP or switch is moved into the Unplaced Devices folder.
• Adopted APs discovered from a controller but without an applicable auto-placement rule are placed
in the same folder as the controller.
• If no Auto-Placement rules criteria match the device, it will be placed in the Unplaced Devices
folder.
• IP based placement uses a single IP address for each device. The selected IP address for Auto-
Placement is the first available address on the following ordered list of IP addresses learned by
AirDefense.
◦ The first IP address on the list is the Devices Management IP Address. This is the IP address that
AirDefense uses to communicate with the device. Due to the use of NAT in the network, this IP
address may be dierent than the actual configured IP address of the device.
◦ The second IP address is the address that the switch provides to AirDefense for the AP. In
adaptive or adopted mode where the AP is discovered through the switch, the system will use
the IP address that the switch has provided for the AP. This IP address is only used by AirDefense
for this purpose and is not saved by AirDefense. It is not used as a configured or managed IP
address for the device, and it will not be displayed by AirDefense.
◦ The switch's IP address will be used for Auto-Placement of the AP if the previous two IP
addresses are not available. The switch's management address is the IP address that is used by
AirDefense to communicate with the switch. It may NOT be the switch's configured IP address.
