Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the GBE link between the subscribers and the
network
The SCE 2000, therefore, only receives traffic and does not transmit.
Figure 3-3
When configuring the SCE 2000, an optical splitter topology is referred to as "receive-only" connection
mode.
Note that in an optical splitter topology, the SCE 2000 only enables traffic monitoring functionality.
When implementing receive-only topologies with a switch, the switch must support SPAN functionality
Note
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

(Figure 3-3). The traffic passes through the optical splitter, which splits traffic to the SCE 2000.
