Note: A session is not the same as an association, which describes a client connection to a
particular access point. A client network connection can shift from one clustered AP
to another within the context of the same session. A client station can roam between
APs and maintain the session.
For information about monitoring associations and link integrity monitoring, see
"Associated Wireless Clients" on page 128.
Table 6.2 Session Information
Field
Description
User Name
Indicates the client user name of IEEE 802.1x clients.
Note: This field is relevant only for clients that are connected to APs using IEEE 802.1x security
AP Location
Indicates the location of the access point.
This is derived from the location description specified on the Basic Settings tab.
Indicates the MAC address of the user's client device (station).
User MAC Address
A MAC address is a hardware address that uniquely identifies each node of a network.
Indicates the amount of time this station has remained inactive.
Idle Time
A station is considered to be "idle" when it is not receiving or transmitting data.
The speed at which this access point is transferring data to the specified client.
Data Rate
The data transmission rate is measured in megabits per second (Mbps).
This value should fall within the range of the advertised rate set for the IEEE 802.1x mode in use on the
access point. For example, 6 to 54Mbps for 802.11a.
Indicates the strength of the radio frequency (RF) signal the client receives from the access point.
Signal
The measure used for this is an IEEE 802.1x value known as Received Signal Strength Indication
(RSSI), and will be a value between 0 and 100.
RSSI is determined by a an IEEE 802.1x mechanism implemented on the network interface card (NIC) of
the client station.
Utilization
Utilization rate for this station.
For example, if the station is "active" (transmitting and receiving data) 90% of the time and inactive 10% of
the time, its "utilization rate" is 90%.
mode and local authentication server. (For more information about this mode, see "IEEE
802.1x" on page 108.) For clients of APs using IEEE 802.1x with RADIUS server or other
security modes, no user name will be shown here.
