Link Integrity Monitoring

The Unified Access Point provides link integrity monitoring to continually verify its
connection to each associated client. To do this monitoring, the AP sends data packets to
clients every few seconds when no other traffic is passing. This allows the access point to
detect when a client goes out of range, even during periods when no normal traffic is
exchanged. The client connection drops off the list within 300 seconds if these data packets are
not acknowledged, even if no disassociation message is received.

Viewing Neighboring Access Points

The status page for Neighboring Access Points provides real-time statistics for all access
points within range of the access point on which you are viewing the Administration Web
pages.
To view information about other access points on the wireless network, click the
Neighboring Access Points tab.
You must enable the AP detection on the AP in order to collect information about other APs
within range.

Field
The "Authenticated" and "Associated" Status shows the underlying IEEE
802.11 authentication and association status, which is present no matter
which type of security the client uses to connect to the AP. This status does
not show IEEE 802.1X authentication or association status.
Some points to keep in mind with regard to this field are:
• If the AP security mode is None or Static WEP, the authentication and
association status of clients showing on the Client Associations tab will
be in line with what is expected; that is, if a client shows as authenticated
to the AP, it will be able to transmit and receive data. (This is because
Static WEP uses only IEEE 802.11 authentication.)
• If the AP uses IEEE 802.1X or WPA security, however, it is possible for
a client association to show on this tab as authenticated (via the IEEE
802.11 security) but actually not be authenticated to the AP via the
second layer of security.
