Wireless Network Management
Monitoring the Wireless Network
In addition to the information that is listed on the Device Information > Wireless
Stations screen (such as MAC address, IP address, Power Save, WLAN, and
VLAN), you can view:
■ Authentication—This field displays the authentication method used—
802.1X Extensible Authentication Protocol (EAP), Web authentication
(Web-Auth), MAC authentication, or none. None is displayed for Wi-Fi
Protected Access (WPA)/WPA2-preshared keys (PSK) and Wired Equiva-
lency Protocol (WEP).
■ Last Active—You can view how many seconds it has been since the station
last sent a frame. If the station is idle for longer than the WLAN’s inactivity
timeout, the Wireless Edge Services xl Module will force the station to
reassociate.
■ QoS Information—Two fields are reported for QoS:
• UAPSD enabled for—This field reports whether the Unscheduled Auto-
matic Power Save Delivery (UAPSD) feature has been enabled.
Designed for Voice over IP (VoIP) and Wi-Fi Multimedia (WMM),
UAPSD preserves the mobile device’s battery life while allowing the
device to control when it “sleeps” and “awakens.” At regular intervals
(configured on and controlled by the mobile device), the mobile
device queries the AP to determine whether the AP has any buffered
frames. (With normal power save mode, the AP contacts the station—
at intervals defined on and controlled by the AP—when the AP has
buffered frames for the station.)
• Service Period—When QoS is enabled for a WLAN, the AP grants a
station a transmission opportunity, allowing the station to transmit a
frame. If an AP grants a station two or more contiguous transmission
opportunities, this is called the service period.
■ BSS Address—This address is the basic SSID (BSSID) on the radio to
which the station connects. Each RP radio has four BSSIDs, which carry
traffic for different WLANs.
■ Voice—This setting indicates whether this station sends voice frames. You
can configure the Wireless Edge Services xl Module to grant higher QoS
for voice traffic.
■ WMM—This setting indicates whether the station supports Wi-Fi Multi-
media (WMM). If it does, then the Web browser interface indicates the
Access Category (AC) that the station is currently using to transmit traffic.
The higher the AC, the better the QoS for the traffic. You can view the
WMM settings associated with that AC on the station’s WLAN by selecting
Network Setup > WLAN Setup and clicking the WMM tab.
■ Encryption—This field displays the encryption method—WEP, WPA/WPA2
with Temporal Key Identity Protocol (TKIP), WPA2 with Advanced
Encryption Standard (AES), or WPA/WPA2 with both TKIP and AES.
