14.6 GigE Operational Setups
The CDM-710G GigE Interface operates as a bridge device and passes traffic between hosts at
different geographic locations on a common
L ocal A rea N etwork (LAN).
The GigE Interface operates like a network hub device which means it acts like a “direct wire”
connection and passes all Ethernet traffic and broadcasts.
Figure 14-4 is an example of using the
GigE Interface to bridge a remote host on a common LAN over the satellite.
It also may be desirable to separate the M&C Ethernet port from the traffic on the GigE Interface
‘J1’ port.
Figure 14-5 shows an example where the M&C Ethernet port has been assigned an IP
address that is NOT on the common LAN. A router is in place at both locations to isolate access
to the M&C port.
