Software User Manual 12/10/09 D-Link UAP Field Network Station Status From Station To Station Table 10: Associated Clients Description Shows which VAP the client is associated with. For example, an entry of wlan0vap2 means the client is associated with Radio 1, VAP 2. An entry of wlan0 means the client is associated with VAP 0 on Radio 1. An entry of wlan1 means the client is associated with VAP 0 on Radio 2. Shows the MAC address of the associated wireless client. 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. Shows the number of packets and bytes received from the wireless client and the number of packets and bytes that were dropped after being received. Shows the number of packets and bytes transmitted from the AP to the wireless client and the number of packets and bytes that were dropped upon transmission. LINK INTEGRITY MONITORING The UAP provides link integrity monitoring to continually verify its connection to each associated client. To do this, the AP sends data packets to clients every few seconds when no other traffic is passing. This allows the AP 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. 34CSFP6XXUAP-SWUM100-D13 Viewing Associated Wireless Client Information Page 33

ONITORING
The UAP provides link integrity monitoring to continually verify its connection to each associated client. To do this, the AP
sends data packets to clients every few seconds when no other traffic is passing. This allows the AP 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.
Table 10:
Associated Clients
Field
Description
Network
Shows which VAP the client is associated with. For example, an entry of wlan0vap2 means the
client is associated with Radio 1, VAP 2.
An entry of wlan0 means the client is associated with VAP 0 on Radio 1. An entry of wlan1
means the client is associated with VAP 0 on Radio 2.
Station
Shows the MAC address of the associated wireless client.
Status
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.
From Station
Shows the number of packets and bytes received from the wireless client and the number of
packets and bytes that were dropped after being received.
To Station
Shows the number of packets and bytes transmitted from the AP to the wireless client and the
number of packets and bytes that were dropped upon transmission.
