If you have the 3e AP con gured in any mode
except
FIPS,
setting TX
Pwr Mode to
Off
will only shut off the power on that one AP.
If you have the 3e AP con gured in FIPS mode and you have de-
ployed the
3e-010F Crypto Client software v 2.6 or higher, however, you
can use this management screen to turn off TX power to this particular AP
and
all client devices associated with it.
In FIPS Wireless AP mode, once you have given the command to turn
off TX power, The screen called
Monitoring/Reports -> Wireless Clients
will contain a column called
EMCON
which shows the results of the
command on any wireless device associated with the AP. This is more
fully explained in
Chapter 7, The RF Manager Function
.
The 3e Access Point Installation CD contains the RF Manager Installa-
tion program. If you install this program, which is explained in Chapter 7,
you can control the TX power level and TX power shutoff from a central
location.
If you turn off TX power, whether from the
Wireless Con guration
— General
page on each AP or using the RF Manager, turning it back on
re-establishes it only in the AP or APs contacted. The
wireless devices that
are associated with those APs will need to re-establish power either by
powering down and then powering up or by removing and reinserting
the PC Card.
Use of the RF Manager allows a Crypto Of cer or Administrator to
manage TX Power level for a group of APs.
In the last section of the Wireless Con guration — General page,
there are a number of advanced options which are described in the fol-
lowing chart:
Beacon interval
0-4095
The frequency in milliseconds in which the
802.11 beacon is transmitted by the AP.
RTS Threshold
0-3000
The number of bytes used for the RTS/CTS
handshake boundary. When a packet size is
greater than the RTS threshold, the RTS/CTS
handshaking is performed.
DTIM
1-65535
The number of beacon intervals between suc-
cessive Delivery Traf c
Identi cation Maps (DTIMs). This feature is
used for Power Save Mode.
Basic Rates
- 1 and 2 Mbps
- 1, 2, 5.5 and 11
Mbps
The basic rates used and reported by the
AP. The highest rate speci ed is the rate that
the AP uses when transmitting broadcast/
multicast and management frames.
Preamble
Short/Long Pre-
amble
Speci es whether frames are transmitted with
the Short or Long Preamble.
Broadcast SSID
Enabled/disabled
When disabled, the AP hides the SSID in
outgoing beacon frames and stations cannot
obtain the SSID through passive scanning.
Also, when it is disabled, the AP doesn’t send
probe responses to probe requests with un-
speci ed SSIDs.
