Physical Topologies

Single Link: Receive-only Topology

In this topology, an external switch resides physically on the FE link between the subscribers and the network. The traffic passes through the external switch, which splits traffic to the SCE 2000. The SCE 2000, therefore, only receives traffic and does not transmit.

Figure 3-2: Single SCE Platform Single Link: Receive-Only Topology

When configuring the SCE 2000, an external switch topology is referred to as “receive-only” connection mode.

Note that in an external switch 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.
