Dell TrueMobile 4350 User Manual page 237

There are three modes of operation for Rogue AP detection (a) Background scan (always-on), (b) Background scan (scheduled) & (c)
Foreground scan.
When the background scan is enabled, the access point will periodically scan the wireless channels (a single channel at a time for 400
ms) if and only if certain load conditions are met. Any wireless stations that are associated to the AP may experience a loss of the AP
during the scan interval. The background scan can either be running continuously or scheduled to run during specific periods. If
scheduled, the background scan should run during periods of inactivity (e.g. during the night or at weekends).
When a foreground scan occurs, the AP will immediately reset and upon reboot will scan all the available wireless channels for an
extended period. A foreground scan will cause immediate termination of all and any wireless clients.

To enable the background scan (always-on) mode of Rogue AP detection, perform the following steps:
1. Click to select Enable Rogue AP Detection (Always-On).
2. Click Save & Restart.
NOTE:Any wireless stations that are associated to the Dell Wireless 4350 Small Network Access Point may experience a loss of
connection to the access point during the scan interval.
Enable Rogue AP Detection - Background Scan (Scheduled):
To enable the background scan mode of Rogue AP detection, perform the following steps:
1. Click to select Enable Rogue AP Detection (Always-On).
2. Click to select Schedule Rogue AP Detection and populate the relevant fields (i.e. Start time, Stop time and specific day of the
week).
3. Click Save & Restart.
NOTE:Any wireless stations that are associated to the Dell Wireless 4350 Small Network Access Point may experience a loss of

Enable Rogue AP Detection - Foreground Scan:
To enable the foreground scan mode of Rogue AP detection, the user must:
1. Click to select Enable Rogue AP Detection (Always-On).
2. Click the Scan Now button.
NOTE:Any wireless stations that are associated to the Dell Wireless 4350 Small Network Access Point will loss connection to the
access point during the scan interval.
The Rogue AP detection parameters can be varied from their default values. The default values are (a) Rogue AP Detection Scan
Interval = 1 minute. (b) Table Entry Removal of Absent Access Points = 1440 minutes (i.e. 24 hours). The Rogue AP Detection Scan
Interval parameter determines how often a background scan may be performed by the access point. The Table Entry Removal of Absent
Access Points parameter determines how long an entry will appear in the table before it is removed.
To configure the Rogue AP Detection Parameters:
1. Click to select Enable Rogue AP Detection (Always-On).
2. Click to select Configure Rogue AP Detection Parameters.
3. Change the appropriate parameter(s) to the desired value(s).
4. Click Save & Restart.
The Table filtering options available are (a) List all AP's (b) List all known AP's & (c) List all rogue AP's. The table of detected AP's
contains a column "Known AP" that allows the user to select whether this AP is either a known or rogue AP (this would normally be
based on information such as SSID & MAC Address). The option "List all AP's" lists all the AP's detected. The option "List all known
AP's" lists all the known AP's detected. The option "List all rogue AP's" lists all the rogue AP's detected.
To change the Table Filtering Options:
1. Click to select Enable Rogue AP Detection (Always-On).
2. Click to select the appropriate table filtering option.
3. Click Save & Restart.
