6. For the Port/Duplex Speed Settings, select the method the network adapter should
use to determine link speed and mode.
Note: Not all connection options are available for all appliance models.
7. In the Unanalyzed Policy list, select one of the following options to determine how
the agent processes traffic when the network is congested.
8. Set the Propagate Link option if the Adapter Mode is set to either inline protection or
inline simulation mode. Select one of the following options:
Method Description
Auto or
Auto Negotiate
Allows two interfaces on a link to select the best common mode
automatically, the moment a cable is connected.
IBM ISS recommends that you use this setting unless you have to
change the setting for a switch or other network device that does not
support auto-negotiation, or if the auto-negotiation process is taking too
long to establish a link.
Auto is the only option available for the GX6116 appliance. It
automatically links at 1 gigabit per second.
10 MB Half Duplex Device either transmits or receives information at 10 megabits per
second, but not at the same time.
10 MB Full Duplex Device transmits information at 10 megabits per second in both
directions at the same time.
100 MB Half
Duplex
Device either transmits or receives information at 100 megabits per
second, but not both at the same time.
100 MB Full
Duplex
Device transmits information at 100 megabits per second in both
directions at the same time.
1000 MB Full
Duplex
Device transmits information at 1000 megabits per second in both
directions at the same time.
Option Description
Forward Forwards traffic without processing it, or fails open to traffic. When traffic levels
return to normal, the agent resumes normal operation.
Note: Always use the Forward setting when the appliance is set to inline
simulation mode.
Drop Blocks some of the traffic without processing it, or fails closed to traffic. When
traffic levels return to normal, the agent returns to normal operation.
Option Description
Auto Uses the most appropriate link setting, based on how the network segment is
configured. The Propagate Link setting behaves as “True” if the appliance is in
Inline Protection, Inline Simulation, or HA mode. It behaves as “False” when the
appliance is in passive monitoring mode.
True The link on the corresponding inline port will be broken when one of the links is
down (such as when a cable is broken or disconnected).
False The link on the corresponding inline port is left intact when one of the links is down.
