802.11 Attributes Tab - Nortel 2350 Reference Manual

248 Configuring Wireless Parameters
• Rogue—Radios use countermeasures against devices classified by WSS Software as
rogues, but do not use countermeasures against devices classified by WSS Software
as interfering devices.
Caution!
radio is sending countermeasures, the radio is disabled for use by network traffic,
until the radio finishes sending the countermeasures.
• Configured—Causes radios to attack only devices specified in the attack list on the
WSS (on-demand countermeasures). When this option is used, devices found to be
rogues by other means, such as policy violations or by determining that the device is
providing connectivity to the wired network, are not attacked.
• Enable Active Scan—Sends probe any requests (probe requests with a null SSID name), to solicit probe
responses from other access points. Radios also passively scan by listening for beacons and probe
responses. When active scan is disabled, radios perform passive scanning only.
• Enable RFID—Enables AeroScout support. (For more information, see the "Configuring APs To Be
AeroScout Listeners" chapter in the
• Enable U-APSD—Enables Unscheduled Automatic Powersave Delivery (U-APSD) on AP radios
managed by the radio profile. U-APSD enables WMM clients that use powersave mode to more
efficiently request buffered unicast packets from AP radios. (For more information, see the "U-APSD
Support" section in the "Configuring Quality of Service" chapter of the
2300 Series Configuration

802.11 Attributes Tab

The 802.11 Attributes tab lists the settings of the following options:
• Beacon Interval—Interval at which the AP advertises its SSIDs. You can specify from 25 to
8191 milliseconds (ms). The default is 100 ms.
• DTIM Period—Number of beacons (1 to 31) the AP transmits before transmitting the multicast and
broadcast frames stored in its buffers. The default is 1.
• Fragment Threshold—Frame length (256 to 2346 bytes) at which the long-retry-count is applicable
instead of the short-retry-count. The default is 2,346 bytes.
• Max. Tx MSDU Lifetime—Maximum amount of time, from 500 ms to 250,000 ms (250 seconds), the
AP can hold an outbound frame in buffer storage. The default value is 2,000 ms (2 seconds).
• Max. Rx MSDU Lifetime—Maximum amount of time, from 500 ms to 250,000 ms (250 seconds), the
AP can hold an inbound frame in buffer storage. The default is 2000 ms (2 seconds).
• RTS Threshold—Minimum length (256 to 3000 bytes) a frame can be for the AP to use the
Request-To-Send/Clear-To-Send (RTS/CTS) method to send the frame. Frames smaller than the RTS
threshold are not sent using the RTS/CTS method. The default is 2346 bytes.
• Enable Long Preambles—Enables advertisement of long preambles for 802.11b/g radios. This option is
enabled by default. This option applies only to 802.11b/g radios.
