Core issue
Rogue Access Point (AP) detection is based on the detection of an unknown radio interface broadcasting over the air. When radio monitoring detects a rogue AP, a new fault is generated.
Resolution
The dadio monitoring feature uses the radio measurement capabilities on Cisco IOS APs and Cisco Client Adapters to discover any new 802.11 APs that are transmitting beacons. Both clients and APs periodically scan for other 802.11 beacon frames on all channels. Reports of detected beacons are returned to the Radio Manager, which validates these beacons against a list of APs known to be authorized to provide wireless access. A newly discovered AP that cannot be identified as a known authorized AP generates an administrator alert. You can categorize this new AP as one of these AP types:
Access Point Category Types
| Type | Description |
| Managed AP | An AP that is authorized to provide wireless access to the LAN and requires management services provided by the WLSE. Note: Only managed APs can participate in Radio Manager operations. |
| Unmanaged AP | An AP that is authorized to provide wireless access to the LAN but does not require any management services from the WLSE. |
| Friendly AP | An AP that is not connected to the LAN, but is known to be detectable by the client's or the AP's 802.11 radios within the managed WLAN. A friendly AP is an AP that you know exists. For example, a neighboring network's AP or a neighboring company's AP. |
| Rogue AP | An AP that may or may not be connected to the LAN is detected by the client's or the AP's 802.11 radios within the managed WLAN, and has not been identified as Friendly, Unmanaged, or Managed. By default, all unknown radios are classified as Rogue until you change them to Friendly, Unmanaged, or Managed. |
Use the fields in this table to change the classification of an AP from Rogue to Friendly or to delete the rogue AP from the database.
