Bridging
The wireless bridging function in the 3e–525A–3 allows use as a
bridge, in a number of alternate confi gurations, including the following
popular confi gurations:
• Point-to-point bridging of 2 Ethernet Links;
• Point-to-multipoint bridging of several Ethernet links;
• Repeater mode (wireless client to wireless bridge.)
Default Confi guration
The 3e–525A–3's default confi guration is an Access Point/Bridge with
FIPS 140-2 submode enabled.
Data Encryption and Security
The 3e–525A–3 Wireless Access Point includes advanced wireless se-
curity features. Over the AP band, you have a choice of no security, Static
WEP, WPA, AES/3DES, depending on your mode of operation. Some
level of security is suggested. Static WEP gives you a choice of 64-bit or
128-bit encryption. WPA includes the option of using a WPA pre-shared
key or, for the enterprise that has a Radius Server installed, confi gura-
tion to use the Radius Server for key management with either TKIP or
AES-CCMP. Bridging encryption is established between 3e–525A–3’s and
includes use of AES-ECB or 3DES encryption (approved by the National
Institute of Standards and Technology (NIST) for U.S. Government and
DoD agencies).
SSID
The Service Set ID (SSID) is a string used to defi ne a common roam-
ing domain among multiple wireless access points. Different SSIDs on
access points can enable overlapping wireless networks. The SSID can
act as a basic password without which the client cannot connect to the
network. However, this is easily overridden by allowing the wireless AP
to broadcast the SSID, which means any client can associate with the AP.
SSID broadcasting can be disabled in the 3e–525A–3 setup menus.
WEP
WEP is an older encryption standard but is preferable to no encryp-
tion. If the 3e–525A–3 is confi gured with WEP encryption, it is compatible
with any 802.11b PC Card confi gured for WEP.
WPA/WPA2 with TKIP/ AES-CCMP
WPA, an interim standard developed by the WiFi Alliance, combines
several technologies. It includes the use of the 802.1x standard and the
Extensible Authentication Protocol (EAP). In addition, it uses, for encryp-
