Parameter Description
WEP Key 2 Second static WEP key associated with the key index. Can be 10 or 26 hex
characters in length.
WEP Key 3 Third Static WEP key associated with the key index. Can be 10 or 26 hex characters
in length.
WEP Key 4 Fourth Static WEP key associated with the key index. Can be 10 or 26 hex
characters in length.
WEP Transmit Key
Index
Key index that specifies which static WEP key is to be used. Can be 1, 2, 3, or 4.
WPA Hexkey WPA pre-shared key (PSK).
WPA Passphrase WPA passphrase with which to generate a pre-shared key (PSK).
Maximum Transmit
Failures
The AP assumes the client has left and should be deauthorized when the AP
detects this number of consecutive frames were not delivered because the
maximum retry threshold as been exceeded.
BC/MC Rate
Optimization
Click this checkbox to enable or disable scanning of all active stations currently
associated to an AP to select the lowest transmission rate for broadcast and
multicast frames. This option only applies to broadcast and multicast data frames;
802.11 management frames are transmitted at the lowest configured rate.
NOTE: Do not enable this parameter unless instructed to do so by your Dell
technical support representative.
Rate Optimization for
delivering EAPOL
frames
Click this checkbox to use a more conservative rate for more reliable delivery of
EAPOL frames.
Strict Spectralink
Voice Protocol (SVP)
Click this checkbox to enable Strict Spectralink Voice Protocol (SVP)
802.11g Beacon Rate Click this drop-down list to select the beacon rate for 802.11g (use for Distributed
Antenna System (DAS) only). Using this parameter in normal operation may cause
connectivity problems.
802.11a Beacon Rate Click this drop-down list to select the beacon rate for 802.11a (use for Distributed
Antenna System (DAS) only). Using this parameter in normal operation may cause
connectivity problems.
Advertise QBSS Load
IE
Click this checkbox to enable the AP to advertise the QBSS load element. The
element includes the following parameters that provide information on the traffic
situation:
l Station count: The total number of stations associated to the QBSS.
l Channel utilization: The percentage of time (normalized to 255) the channel
is sensed to be busy. The access point uses either the physical or the virtual
carrier sense mechanism to sense a busy channel.
l Available admission capacity: The remaining amount of medium time
(measured as number of 32us/s) available for a station via explicit admission
control.
The QAP uses these parameters to decide whether to accept an admission control
request. A wireless station uses these parameters to choose the appropriate
access points.
NOTE: Ensure that WMM is enabled for legacy APs to advertise the QBSS load
element. For 802.11n APs, ensure that either wmm or high throughput is enabled.
