Rogue Scan Data Collection
The AP stores information gathered about detected stations during scanning in a Rogue Scan result table. The Rogue
Scan result table can store a maximum of 2000 entries. When the table fills, the oldest entry gets overwritten. The Rogue
Scan result table lists the following information about each detected station:
• Station Type: indicates one of the following types of station:
– Unknown station
– AP station
– Infrastructure Client Station
– IBSS Client Station
• MAC Address of the detected station
• Channel: the working channel of the detected station
• SNR: the SNR value of the last frame from the station as received by the AP
• BSSID: the BSSID field stores the:
– MAC address of the associated Access Point in the case of a client.
– Zero MAC address or MAC address of the partner Access Point if the AP is a partner of a WDS link
The AP ages out older entries in the Rogue Scan result table if a detected station is inactive for more than the Scan
Result Table Ageing Time.
Rogue Scan
Perform this procedure to enable Rogue Scan on a particular interface or interfaces and define the Scan Interval and
Scan Interface. See Figure
The Rogue Scan screen also displays the number of new access points and clients detected in the last scan on each
wireless interface.
1. Enable the Security Alarm Group. Select the Security Alarm Group link from the Rogue Scan screen. Configure a
Trap Host to receive the list of access points (and clients) detected during the scan.
2. Click Configure > Alarms > Rogue Scan.
3. Enable Rogue Scan on the wireless interface by checking Enable Rogue Scan.
NOTE: Rogue Scan cannot be enabled on a wireless interface when the Wireless Service Status on that interface is
shutdown. First, resume service on the wireless interface.
NOTE: Enabling Rogue Scan simultaneously with Broadcast Unique Beacon will cause a drift in the beacon interval
and the occasional missing of beacons.
4. Enter the Scan Mode. Select Background Scanning or Continuous Scanning. In Continuous Scanning mode the AP
stops normal operation and scans continuously on that interface. In Background Scanning mode, the AP performs
background scanning while doing normal AP operation on that interface.
5. If the Scan Mode is Background Scanning, then enter the Scan Interval.
• The Scan Interval specifies the time period in minutes between scans in Background Scanning mode and can be
set to any value between 1 and 1440 minutes.
6. Configure the Scan Result Table Ageing Time. The AP ages out older entries in the Rogue Scan result table if a
detected station is inactive for more than this time. The valid range is from 60-7200 minutes, the default is 60 minutes.
7. Configure the Scan Results Trap Notification Mode to control the notification behavior when APs or stations are
detected in a scan:
• No Notification
• Notify AP
