Displaying the Source Address List

The Source Address List, or Table (SAT), contains the MAC address and its associated vendor name for each device communicating through a port in the SEHI (or SEHI-controlled) hub. Each detected source address is also identified by the module and port through which it is communicating with the SEHI.

To view a SEHI’s Source Address List:

from the icon:

1.Click on the appropriate device icon to display the icon menu.

2.Drag down to Source Address and release.

from the Hub View:

1.Click on to display the Device menu.

2.Drag down to Source Addressing and release.

from the command line (stand-alone mode):

1.From the appropriate directory, type
