Viewing Session Information For Access Points
8.3 Viewing Session Information For Access Points
You can view session information for all access points on the network at the same
time, or set the display to show session information for a specified access point
chosen from the drop-down menu at the top of the screen.
To view information on all access points, select the Show all access points radio
button at the top of the page.
To view session information on a particular access point, select the Show only this
access point radio button and choose the access point name from the drop-down menu.
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 Indica-
tion (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 inac-
tive 10% of the time, its “utilization rate” is 90%.
Receive Total Indicates number of total packets received by the client during the current session.
Transmit Total Indicates number of total packets transmitted to the client during this session.
Error Rate Indicates the percentage of time frames are dropped during transmission on this access point.
