Link Integrity Monitoring - Linksys LAPAC1750PRO User Manual

LAPAC1750PRO Access Point Software User Manual
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 other (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
These fields report information about traffic sent from a wireless client to
the AP
Packets The number of packets received from the wireless client
Bytes The number of bytes received from the wireless client
Drop Packets The number of packets that were dropped after being
received
Drop Bytes The number of bytes that were dropped after being
received
TS Violate
The number of packets sent from a wireless client to the
AP in excess of its active TS uplink bandwidth, or for an
Packets
access category requiring admission control to which
the wireless client has not been admitted

To Station
These fields report information about traffic sent from the AP to a wireless
client
Packets The number of packets sent from the AP to the wireless
client
Bytes The number of bytes sent from the AP to the wireless
client
Drop Packets The number of packets that the AP attempted to send to
the wireless client but were dropped
Drop Bytes The number of bytes that the AP attempted to send to
the wireless client but were dropped
TS Violate The number of packets sent from the AP to a wireless
client in excess of its active TS downlink bandwidth, or
Packets
for an access category requiring admission control to
which the wireless client has not been admitted

Link Integrity Monitoring

The access point 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
