Single Link: Receive-only Topology
In this topology, an external optical splitter resides physically on the GBE link between the subscriber side and the network side.
The external splitter is connected to the SCE 1000 via Rx links only.
In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The SCE 1000, therefore,
is in receive-only topology, having only traffic monitoring capabilities.
Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN functionality that
Note
includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Configure GigabitEthernet Auto-Negotiation
By default, the SCE 1000 GBE line interface ports are configured with auto-negotiation disabled.
If you change any parameters, you must save the new configuration settings. Type copy running-config startup-config,
