Detecting Rogue APs 59
Detected and Known AP lists
When the M220 discovers an AP during a scan, it compares the MAC address of the AP
against the Known AP list (a list that you create or import using the capabilities on this
page). If the scanned AP does not appear in the list of known APs, it is displayed in the
Detected rogue AP list.
The following information displays for each detected rogue AP:
Field Description
MAC The MAC address of the neighboring AP detected during a scan.
Beacon Int. The Beacon interval being used by this AP. Beacon frames are
transmitted by an AP at regular intervals to announce the existence of
the wireless network. The default behavior is to send a beacon frame
once every 100 milliseconds (10 per second).
Type The type of device:
• AP indicates the neighboring device is an AP that supports the
IEEE 802.11 Wireless Networking Framework in Infrastructure
mode.
• Ad hoc indicates a neighboring wireless client device running in
Ad hoc mode. Devices set to Ad hoc mode communicate with each
other directly, without the use of a traditional AP. Ad hoc mode is
an IEEE 802.11 Wireless Networking Framework also referred to as
peer-to-peer mode or an Independent Basic Service Set (IBSS).
SSID The Service Set Identifier (SSID) for the AP.
The SSID uniquely identifies a wireless LAN and is also referred to as
the Network Name. It can be up to 32 alphanumeric characters.
Privacy Whether there is any security on the neighboring device.
• Off indicates that the Security mode on the neighboring device is
set to None (no security).
• On indicates that the neighboring device has some security in
place.
