8.2 Understanding Session Monitoring Information
The Sessions page shows information on client stations associated with access
points in the cluster. Each client is identified by user name and user MAC address,
along with the AP (location) to which it is currently connected.
To view a particular statistic for client sessions, select an item from the Display
drop-down list and click Go. You can view information on Idle Time, Data Rate,
Signal, Utilization, and so on; all of which are described in detail in Table 8.1.
A “session” in this context is the period of time in which a user on a client device
(station) with a unique MAC address maintains a connection with the wireless net-
work. The session begins when the client logs on to the network, and the session
ends when the client either logs off intentionally or loses the connection for some
other reason.
Notes: A session is not the same as an association, which describes a client con-
nection 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 monitor-
ing, see “Associated Wireless Clients” on page 214.
Details about the session information shown is described below.
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 mode and local authentication server. (For more information
about this mode, see “IEEE 802.1x” on page 131.) For clients of APs using
IEEE 802.1x with RADIUS server or other security modes, no user name will be
shown here.
AP Location Indicates the location of the access point.
This is derived from the location description specified on the Basic Settings tab.
User MAC Address Indicates the MAC address of the user’s client device (station).
A
MAC address is a hardware address that uniquely identifies each node of a network.
