Configuring MAP Access Points 151
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:
WX1200# 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 transmitted 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:
WX1200# set radio-profile rp1 max-tx-lifetime 4000
success: change accepted.
Disabling 802.11b Client Associations on 802.11b/g Radios By
default, an 802.11b/g radio allows associations from 802.11b clients as
well as 802.11g clients. The radio requires a client to support the
802.11b data rates but client support for the higher 802.11g rates is
optional. This radio configuration allows both types of clients to associate
with the radio and is useful in networks that have a mixture of both types
of clients.
When 802.11b traffic is detected by an 802.11b/g radio, the radio enters
protection mode. Protection mode guards against 802.11b interference
with 802.11g traffic that is at data rates higher than the 802.11b rates.
Because 802.11b clients cannot detect the traffic at data rates higher
than are supported by 802.11b, the clients might cause interference by
sending traffic while 802.11g access points or clients also are sending
traffic.
