Chapter 6: Managing Access Points & Clusters

Understanding Session Monitoring Information

Psion Teklogix 9160 G2 Wireless Gateway User Manual 63

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

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.

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).

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).

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.

Signal

Indicates the strength of the radio frequency (RF) signal the client receives from the access point.

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%.
