On the New/Edit BSS screens, these additional settings apply
to
WPA, WPA2 and WPA2-Mixed selections:
WPA Rekey Period - specifies the interval at which new pair-
wise transient keys (PTKs) are negotiated or
0 (zero),
which disables the rekeying function: the interface will use
the same key for the duration of each session seconds.
Specify a new interval in whole seconds between
0 and
2147483647, inclusive. No WPA Rekey Period is specified
by default.
NOTE: WPA Preau-
thentication
applies
only to
wpa2 and wpa2
mixed
enterprise mode
Wi-Fi Security settings. It
is not present when
wpa
is selected
.
WPA Preauthentication - to facilitate roaming between
network access points, enabling
WPA Preauthentication on
the BSS permits approaching WPA2 wireless clients to
authenticate on the Bridge while still connected to another
network access point, while wireless clients moving away
from the Bridge can remain connected while they
authenticate on the next network AP.
WPA Preauthentication
is
Disabled by default.
WPA-PSK, WPA2-PSK and WPA2-Mixed-PSK Security
WPA-PSK (Wi-Fi Protected Access) and WPA2-PSK are the
pre-shared key modes of WPA (as distinguished from the
enterprise modes described above). You can specify that WPA-
PSK
or WPA2-PSK be used exclusively by the BSS, or you can
configure it to be able to use either by selecting
WPA2-Mixed-
PSK
.
Pre-shared key mode differs from enterprise mode in that PSK
bases initial key generation on a user-specified key or
passphrase instead of through digital certificates. Like
enterprise-mode, PSK mode generates encryption keys
dynamically and exchange keys automatically with connected
devices at user-specified intervals.

On the New/Edit BSS screens, these additional settings apply
to
WPA-PSK, WPA2-PSK and WPA2-Mixed-PSK selections:
WPA Rekey Period - specifies the interval at which new
keys are negotiated. Specify a new interval in whole
seconds between
1 and 2147483647, inclusive, or 0 (zero)
to permit the same key to be used for the duration of the
session.
Preshared Key Type - determines whether the specified key
is an
ASCII passphrase or a Hexadecimal key.
