set radio-profile rts-threshold 365
Usage — Changing the preamble length value affects only the support
advertised by the radio. Regardless of the preamble length setting ( short
or long ), an 802.11b/g radio accepts and can generate 802.11b/g frames
with either short or long preambles.
If a client associated with an 802.11b/g radio uses long preambles for
unicast traffic, the MAP access point still accepts frames with short
preambles but does not transmit frames with short preambles. This
change also occurs if the access point overhears a beacon from an
802.11b/g radio on another access point that indicates the radio has
clients that require long preambles.
You must disable all radios that use a radio profile before you can change
parameters in the profile. Use the
set radio-profile mode command.
Examples — The following command configures 802.11b/g radios that
use the radio profile rp_long to advertise support for long preambles
instead of short preambles:
WX4400# set radio-profile rp_long preamble-length long
success: change accepted.

rts-threshold
Changes the RTS threshold for the MAP radios in a radio profile. The RTS
threshold specifies the maximum length a frame can be before the radio
uses the RTS/CTS method to send the frame. The RTS/CTS method clears
the air of other traffic to avoid corruption of the frame due to a collision
with another frame.
Syntax —
set radio-profile name rts-threshold threshold
„
name — Radio profile name.
„
threshold — Maximum frame length, in bytes. You can enter a value
from 256 through 3000.
Defaults — The default RTS threshold for a MAP radio is 2346 bytes.
Access — Enabled.
