Auto-Placement rules determine where devices will be placed in the network tree when they are imported. Any device that has the specified parameter(s) and qualifying value(s) will be placed in the selected network level.
Auto-Placement rules are applied differently based on the device type that are discovered in your network. The rules are different for sensors when compared to rules for access points and switches.
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.
Auto-Placement rules for APs and switches are applied when APs or switches are manually added or 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 access points 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 different 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.
