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 Equivalency 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 zl 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 con-
trolled 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 zl Module to grant higher QoS for voice
traffic.
■ WMM—This setting indicates whether the station supports Wi-Fi Multimedia
(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.
