Physical Topologies

Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the GBE link between the subscribers and the network. 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 3-1: 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.

Physical Topologies

Following are descriptions of a number of physical topologies that the SCE 2000 supports.

Single SCE 2000 Topologies

A single SCE 2000 supports both single GBE link and dual GBE link topologies.
