Router Mode (Requires Optional IP Packet Processor)
•
When the optional IP Packet Processor is installed and enabled, you should use Port 1 of
each modem for M&C purposes only. Reserve use of Port 2, 3, or 4 for each modem for
Ethernet traffic only.
•
TO AVOID ETHERNET NETWORKING LOOPS – Make sure to connect Port 1 (M&C) and the
designated Traffic Port to separate Layer 2 Switches, unless your Layer 2 Switch is
configured to isolate these ports by using VLANs.
Figure 5-15 shows the block diagram for a CDM-625A or CDM-625 1:1 modem configuration using the IP
(10/100 Ethernet) Interface in Router Mode, with the optional IP Packet Processor installed and
enabled. The Figure 5-16 cabling example shows Ethernet Port 2 as the designated Ethernet traffic
connection.
This configuration requires no cabling kit – you must use user-provided Ethernet cables and Layer 2
switch(es) for direct connection to the modem.
