FIPS 802.11i
If you wish to use FIPS 802.11i on the 3e–525A–3, enable either Pre-
shared Key Settings or 802.1x Settings.
If you are a SOHO user, selecting pre-shared key means that you
don’t have the expense of installing a Radius Server. Simply input up to
63 character / numeric / hexadecimals in the Passphrase fi eld.
Enable pre-authentication to allow a client to authenticate in advance
with the AP before the client is associated with it. Allowing the AP to
pre-authenticate a client decreases the transition time when a client roams
between APs.
As an alternative, for business applications who have installed Ra-
dius Servers, select 802.1x and input the Primary Radius Server and RFC
Backend security settings. Use of Radius Server for key management and
authentication requires that you have installed a separate certifi cation sys-
tem and each client must have been issued an authentication certifi cate.
Re-keying time is the frequency in which new encryption keys are
generated and distributed to the client. The more frequent re-keying, the
better the security. For highest security, select the lowest re-keying inter-
val.
Once you have selected the options you will use, click Apply .
