Note: Quarantine Status, Defending Sensor, Port Block Status, and Port Block Details fields are not visible if WIDS
license is applied.
Note: If the selected AP is currently quarantined, a Remove from Quarantine button appears in the AP Properties dialog.
Click <Remove from Quarantine> to view an Information message and to enable wireless communication to the AP.
AP Quarantine Confirmation Dialog
Note: The system quarantines only those interfaces that are mis-configured (non-policy compliant). The system allows policy
compliant interfaces to operate unhindered.
Defending Sensor: If an AP is quarantined, it specifies the name of the Sensor that is actively
preventing the AP from engaging in wireless communication.
Port Block Status: Click to block the wired side Ethernet port to which the AP is connected.
WLSE integration is needed to block wired side Ethernet port of the AP.
AP Port Block Status Dialog
Port Block Details: Specifies the IP address of the switch and the port to which the AP is connected.
Beacon Interval (ms): Specifies in milliseconds the time interval between successive beacons of the AP.
First Detected At: Specifies the date and time when the AP was first detected by the system.
802.11n Properties: Appears when the AP is 802.11n capable.
Channel Width: Specifies whether an AP is operating on 20 MHz or 40 MHz channel width. 802.11n allows
for the use of standard channel width of 20 MHz or double channel width of 40 MHz. 40 MHz channel
width is achieved by using two adjacent channels to send data simultaneously.
Channel Offset: For AP operating on 40 MHz channel width, channel offset specifies whether the adjacent
channel used in 40 MHz operation is above or below the primary channel. This field can have following
values:
Above 40 MHz: AP is currently operating on 40 MHz and adjacent channel lies above the primary
channel.
Below 40 MHz: AP is currently operating on 40 MHz and adjacent channel lies below the primary
channel.
802.11n Data Rate: Specifies the highest 11n rate of the AP with which it communicates with the Client.
Short G1 for 20 MHz: Indicates if the AP is capable of using short guard interval for 20 MHz.
Short G1 for 40 MHz: Indicates if the AP is capable of using short guard interval for 40 MHz.
MCS Support: Specifies the various Modulation and Coding Schemes (MCS) supported for 802.11n. The
802.11n standard defines a total of 77 MCS. Each MCS is a combination of a certain modulation (for example,
