set radio-profile preamble-length 419
set radio-profile
preamble-length
Changes the preamble length for which an 802.11b/g MAP radio
advertises support. This command does not apply to 802.11a.
Syntax —
set radio-profile name
preamble-length
{long | short}
name — Radio profile name.
long — Advertises support for long preambles.
short — Advertises support for short preambles.
Defaults — The default is short.
Access — Enabled.
History —Introduced in MSS Version 3.0.
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 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.
