values.
Setting Default Description
Allow Automatic
Channel Selection
(2.4, 5, and 4.9GHz
Public Safety)
No
If enabled, whenever the AP is rebooted it uses its radio to scan the
airspace and select its optimal RF channel based on observed signal
strength from other radios.
NOTE: If you enable this feature, AirWave automatically reboots the APs
in the group when the change is implemented.
802.11b Data Rates
(Mbps)
Required:
l 1.0
l 2.0
Optional:
l 5.5
l 11.0
Displays pull-down menus for various data rates for transmitting data.
NOTE: This setting does not apply to Cisco LWAPP devices.
The three values in each of the pull-down menus are as follows:
l Required—The AP transmits only unicast packets at the specified data
rate; multicast packets are sent at a higher data rate set to optional.
(Corresponds to a setting of yes on Cisco devices.)
l Optional—The AP transmits both unicast and multicast at the specified
data rate. (Corresponds to a setting of basic on Cisco devices.)
l Not Used—The AP does not transmit data at the specified data rate.
(Corresponds to a setting of no on Cisco devices.)
Frag Threshold
Enabled
No
If enabled, this setting enables packets to be sent as several pieces
instead of as one block. In most cases, leave this option disabled.
Threshold Value (256-
2347 bytes)
2337
If Fragmentation Threshold is enabled, this specifies the size (in bytes) at
which packets are fragmented. A lower Fragmentation Threshold setting
might be required if there is a great deal of radio interference.
RTS/CTS Threshold
Enabled
No
If enabled, this setting configures the AP to issue a RTS (Request to Send)
before sending a packet. In most cases, leave this option disabled.
RTS/CTS Threshold
Value (0-2347 bytes)
2338
If RTS/CTS is enabled, this specifies the size of the packet (in bytes) at
which the AP sends the RTS before sending the packet.
