Field Description
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 the table below.
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 network. 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.
Details about the session information shown is described below.
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” in this manual.
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” in “Configuring Security” .) 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.
Idle Time
Indicates the amount of time this station has remained inactive.
A station is considered to be “idle” when it is not receiving or
transmitting data.
Data Rate
The speed at which this access point is transferring data to the
specified client.
The data transmission rate is measured in megabits per
second (Mbps)
