Figure 11 WCS WLAN Client Location Map
Note that beginning with Release 4.0 of WCS, it is possible to filter the location information displayed
by WCS based on the age of the information. Thus, in Figure 11, WCS displays location server
information that has aged up to 15 minutes. This value can be set to 2 or 5 minutes if you want to see
location information that was received more recently or ½, 1, 3, 6, 12, or 24 hours for information that
is even older.
Several options are available by clicking on the blue rectangle icon under View Filters:
• The total number of WLAN clients detected on this floor.
• Small icons (shown above) or regular-sized icons can be selected. When using small icons, no text
is displayed on the floor map for the client except when a mouse-over is performed. When using
regular-size icons, an on-screen tag is displayed that is configurable for IP address, user name, MAC
address, asset name, asset group, or asset category.
• Either all WLAN clients can be displayed, or filtering can be performed to select which clients to
display on the floor map. This can be based on IP address, user name, MAC address, asset name,
asset group, asset category, or controller. Additional filtering can be specified for SSID and RF
protocol (802.11a or 802.11b/g).
Complete information on any displayed WLAN client can be obtained simply by left-clicking on the
appropriate blue rectangular icon on the floor map. Figure 12 illustrates the results with a full set of
client statistics (including bytes sent/received, packets sent/received, policy error counts, last
RSSI/SNR, and retry counts) presented for each client along with any current access point information.
Note that name, group, and category information can be assigned to the client, which can be then be used
to identify the asset on the floor map display. Historical trending of client statistics is presented in a
easy-to-read graphical format. Additional details regarding any point on the graphs can be obtained
simply by performing a mouse-over of the point in question.
