This 

User’s Guide

 is also accessible from any Help window. 

The Linktropy Monitor displays real-time statistics and throughput graphs of the traffic traversing 
the emulated WAN link. See Section 9 for details on the Linktropy Monitor. 

 

 

Figure 4: Status Box and Message Bar 

3.2 Status Box 

The Status Box, at the top right corner of the Configuration window, displays interface status and 
basic statistics, and is visible across all tabs.   

The Status Box displays the status of the LAN A and LAN B Ethernet interfaces. During normal 
operation, the speed and duplex state of the interface are displayed in green. If the interface is 
unplugged or fails to negotiate an Ethernet connection, “

DOWN

” is displayed in red.   

When emulation is turned on, the Status Box displays the current instantaneous throughput in 
each direction, averaged over 1 second intervals, and the total number of dropped frames. More 
detailed statistics and throughput graphs are shown in the Linktropy Monitor. 

3.3 Emulation On/Off Button 

The Emulation On/Off Button displays and controls the state of the currently selected link. The 
button is gray when emulation is off and green when emulation is on. Click the button to toggle 
between on and off. 

Emulation is turned off by default when the Linktropy WAN emulator is first installed.
