D-Link DWS-1008 CLI Manual 349
set radio-profile preamble-length
Changes the preamble length for which an 802.11b/g DWL-8220AP radio advertises support.
This command does not apply to 802.11a.
Syntax: set radio-profile name preamble-length {long | short}
name
long
short
Defaults: The default is short.
Access: Enabled.
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 DWL-
8220AP 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:
DWS-1008# set radio-profile rp_long preamble-length long
success: change accepted.
