Software overview
NOTE
When using a Mobility 5181 for use with WIPS and as a sensor you must first configure the WIPS
server IP Addresses before converting the Mobility 5181 to a sensor.
Rogue AP detection
The controller supports the following techniques for rogue AP detection:
•
•
•
•
•
RF scan by Access Point on one channel
This process requires an Access Point to assist in Rogue AP detection. It functions as follows:
•
•
•
•
This process of detecting a Rogue AP is non-disruptive and none of the Clients are disassociated
during this process. The Access Point will only scan on its present channel. A Mobility 300 provides
this support.
By choosing this option for detection, all capable Access Points will be polled for getting the
information.
RF scan by Access Point on all channels
The process used to scan for Rogue APs on all available channels functions as follows:
•
•
•
•
SNMP Trap on discovery
An SNMP trap is sent for each detected and Rogue AP. Rogue APs are only detected, and
notification is provided via a SNMP trap.
NOTE
Wired side scanning for Rogue APs using WNMP is not supported. Similarly, Radius lookup for
approved AP is not provided.

Authorized AP lists
Rogue AP report
The controller sends a new configuration message to the adopted AP informing it to detect
Rogue APs.
The Access Point listens for beacons on its present channel.
It passes the beacons to the controller as it receives them without any modification.
The controller processes these beacon messages to generate the list of APs
The controller sends a configuration message (with the ACS bit set and channel dwell time) to
the Access Point.
An Access Point starts scanning each channel and passes the beacons it hears on each
channel to the controller.
An Access Point resets itself after scanning all channels.
An controller then processes this information
