Configuring virtual adapters on the Gen2 card

Q
Ports 1-4 are monitoring a collection of trunked links
Q
The remaining ports are each connected to the SPAN (or
mirror) port on a switch
In this scenario, it makes sense for Observer to view Ports 1-4 as a
single data stream and to separate each of the four remaining ports
into separate data streams.
Virtual adapters are a convenient way to accomplish this separation in
real time, rather than depending on filters to sort through the traffic
post-capture. A physical port cannot belong to more than one virtual
adapter.
To define a subset of Gen2 ports as a single virtual adapter,
1 Right-click the Gen2-equipped probe from Observer’s probe list
and choose Probe or Device Properties from the menu.You can tell
the probe is a GigaStor probe because (Gigabit) appears after the
probe name (Figure 77).

2 Click the Virtual Adapters tab and click Edit Adapter. By default
all of the ports are assigned to the adapter. You must remove ports
if you want to have multiple virtual adapters. See Figure 23 for a
diagram of the physical ports assignments.
