Interfaces
NOTE: Turbo mode is supported in 802.11a and 802.11g mode. If turbo mode is enabled, then this is displayed in
the web UI and the transmit speeds and channels pull-down menus are updated with the valid values.
• DTIM Period: The Deferred Traffic Indicator Map (DTIM) Period determines when to transmit broadcast and multicast
packets to all clients. If any clients are in power save mode, packets are sent at the end of the DTIM period. This
parameter supports a range between 1 and 255; it is recommended to leave the DTIM at its default value unless
instructed by technical support. Higher values conserve client battery life at the expense of network performance for
broadcast or multicast traffic.
• RTS/CTS Medium Reservation: This parameter affects message flow control and should not be changed under
normal circumstances. Range is 0 to 2347. When set to a value between 0 and 2347, the Access Point uses the
RTS/CTS mechanism for packets that are the specified size or greater. When set to 2347 (the default setting),
RTS/CTS is disabled. See
• Enable Closed System: When enabled, the AP will not respond to probe requests from client stations requesting
"ANY." Enabling closed system will require the client station to configure the SSID of the AP manually.
• Wireless Service Status: Select Shutdown to shutdown the wireless service on a wireless interface, or resume to
resume wireless service. See
• Load Balancing Max Clients: Load balancing distributes clients among available access points. Enter a number
between 1 and 63 to specify the maximum number of clients to allow.
• Channel Blacklist Table: The Channel Blacklist table contains all available channels. It can be used to manually
blacklist channels, and it also reflects channels that have been automatically blacklisted by the
Selection/Radar Detection (DFS/RD)
• Wireless Distribution System: A Wireless Distribution system can be used to establish point-to-point (i.e. wireless
backhaul) connections with other access points. See
information.
Dynamic Frequency Selection/Radar Detection (DFS/RD)
In order to prevent interference with radar systems and other devices that occupy the 5 GHz band, 802.11a APs certified
in the ETSI (Europe) regulatory domain (see
operating channel through a combination of Auto Channel Select (ACS) and Dynamic Frequency Selection (DFS)/Radar
Detection (RD).
During boot-up, ACS scans the available channels and selects the best channel. Once a channel is selected, the AP
performs a channel availability check for 60 seconds to ensure that there is no radar on the channel and then
commences normal operation. When the AP enters normal operation, DFS works in the background to detect radar
interference on that channel. If interference is detected, the AP sends a trap, disassociates all clients, blacklists the
channel, and reboots. After it reboots, ACS re-scans and selects a better channel that is free of interference.
If ACS is disabled, only channels in the lower frequency band are available for use:
• 36: 5.18 GHz (default)
• 40: 5.200 GHz
• 44: 5.220 GHz
• 48: 5.240 GHz
