K.2.2 Modes of Ethernet Operation
The Ethernet interface is configurable for
Managed Switch Mode
when the optional IP Packet
Processor is either
not installed
or
installed but disabled
; or in
Router Mode or Managed
Switch Mode
when the optional IP Packet Processor is
installed
and
enabled
. This interface
design allows for multiple customer Ethernet interfaces, as well as the convenience of daisy-
chaining together of multiple CDM-625As.
Additionally, because the M&C processor is connected to the internal Ethernet Switch, M&C
traffic is available via all LAN interfaces as well as via the over-the-air WAN interface.
K.2.3 Ethernet Networking Loops
Figure K-2. Improper Use of External Ethernet Switch with CDM-625A
It should be noted that care must be taken to avoid
Ethernet Networking Loops
. Specifically,
the network operator must make sure to avoid connecting multiple ports of the CDM-625A to
the same external Ethernet switch, as shown in
Figure K-3. Ethernet Networking Loop Example (Simplified)
shows a simplified version of this loop. As shown here, two switches have been
connected – each switch has two or more separate connections. This is
not
how the CDM-625A’s
Ethernet switches are designed to be used, and this configuration will cause a network outage.
