To change the RTS threshold for radio profile rp1 to 1500 bytes, type the following command:
WSS# set radio-profile rp1 rts-threshold 1500
success: change accepted.
Changing the fragmentation threshold
The fragmentation threshold specifies the longest a frame can be without being fragmented into multiple
frames by a radio before transmission. To change the fragmentation threshold, use the following command:
set radio-profile name frag-threshold threshold
The threshold can be a value from 256 through 2346. The default is 2346.
To change the fragmentation threshold for radio profile rp1 to 1500 bytes, type the following command:
WSS# set radio-profile rp1 frag-threshold 1500
success: change accepted.
Changing the maximum receive threshold
The maximum receive threshold specifies the number of milliseconds a frame received by a radio can remain
in buffer memory. To change the maximum receive lifetime, use the following command:
set radio-profile name max-rx-lifetime time
The time can be from 500 ms (0.5 second) through 250,000 ms (250 seconds). The default is 2000 ms
(2 seconds).
To change the maximum receive threshold for radio profile rp1 to 4000 ms, type the following command:
WSS# set radio-profile rp1 max-rx-lifetime 4000
success: change accepted.
Changing the maximum transmit threshold
The maximum transmission threshold specifies the number of milliseconds a frame scheduled to be trans-
mitted by a radio can remain in buffer memory. To change the maximum transmit lifetime, use the following
command:
set radio-profile name max-tx-lifetime time
The time can be from 500 ms (0.5 second) through 250,000 ms (250 seconds). The default is 2000 ms
(2 seconds).
To change the maximum transmit threshold for radio profile rp1 to 4000 ms, type the following command:
WSS# set radio-profile rp1 max-tx-lifetime 4000
success: change accepted.
Changing the preamble length
By default, 802.11b/g radios advertise support for frames with short preambles and can support frames with
short or long preambles.
