Security; Selecting A Virtual Access Point (Vap); Configuring Authentication; Configuring Encryption - 3Com 8250 User Manual

S
ECURITY
The Security page allows you to set up lower-layer client authentication and data
encryption parameters as described below.
Note: Because of limitations in the Virtual Access Point feature, VAPs on the same
physical interface share the same WEP keys; therefore, the WEP configuration
section applies to both VAPs.
When you are finished configuring items on this page, click Apply.
S
Open the Virtual AP drop-down box and select the VAP you want to configure.
Each VAP has its own set of security parameters except for the WEP key table,
which is shared between two VAPs.
C
The following types of authentication can be configured:
C
The following types of data encryption are available:
The access points contending for the medium may not be aware of each
other. The RTS/CTS mechanism can solve this hidden node problem. (Default:
2346)
Preamble Length (802.11g and 802.11b only)—IEEE 802.11 frames begin
with an alternating pattern of 1s and 0s called the preamble, which tells
receiving stations that a frame is arriving. This provides time for the receiving
station to synchronize to the incoming data stream. Enabling the Short
preamble can boost your throughput; however, this can cause interoperability
issues. (Default: Long)
