Expert Layers and Objects
During capture, the Expert constructs a database of network objects
from the traffic it sees and categorizes network problems according to
the Expert layer at which they occur.
NOTE: The Expert’s network layering structure is similar to the OSI
model. However, the two schemes do not always map on a
one-to-one basis.
To configure network object and Expert layer options, select Expert
Options from the Tools menu. The Expert Properties dialog box opens
displaying the Objects tab.
The Expert has configuration options that enable you to:
Exclude certain layers from Expert processing. In addition to
using capture filters, which let you select the particular traffic you
need for network analysis, you can exclude certain Expert layers
from processing. Double-click a layer in the Analyze column of the
Objects tab and select No to exclude the layer from Expert
processing
