Conﬁguring DWL-8220AP Access Points

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.

To guard against interference, an 802.11b/g radio in protection mode sends messages while

802.11g trafﬁc at higher data rates is being sent, to inform 802.11b devices about the 802.11g

trafﬁc and reserve bandwidth for the trafﬁc. Protection mode remains in effect until 60 seconds

after the last 802.11b trafﬁc is detected by the 802.11b/g radio.

Protection mode lowers overall trafﬁc throughput due to the additional messages sent by

802.11b/g radios. You can conﬁgure the 802.11b/g radios in a radio proﬁle to reject association

attempts by 802.11b clients so that protection mode is less likely to be required. In this case,

the 802.11b/g radios require a client to support all the 802.11g rates.

Note:

Even when association of 802.11b clients is disabled, if an 802.11b/g radio detects

a beacon from an 802.11b network, the radio enters protection mode to protect against

interference.

To conﬁgure 802.11b/g radios to reject association attempts from 802.11b clients, use the

following command:

set

radio-proﬁle

name

11g-only

{

enable

disable

}

To conﬁgure the 802.11b/g radios in radio proﬁle

rp1

to allow associations from 802.11g

clients only, type the following command:

DWS-1008#

set radio-proﬁle rp1 11g-only enable

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.

An 802.11b/g radio generates unicast frames to send to a client with the preamble length

speciﬁed by the client. An 802.11b/g radio always uses a long preamble in beacons, probe

responses, and other broadcast or multicast trafﬁc.
