Information About Topology Considerations
Single Link: Receive-only Topology
In this topology, an optical splitter resides physically on the GBE link between the subscribers and the
network (
Figure 3-3 ). The traffic passes through the optical splitter, which splits traffic to the SCE 2000.
The SCE 2000, therefore, only receives traffic and does not transmit.
Figure 3-3 Single SCE Platform Single Link: Receive-Only Topology
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.
Note
When implementing receive-only topologies with a switch, the switch must support SPAN functionality
that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.
