Dual Link: Receive-Only Topology

In this topology, one Cisco SCE 8000 is connected in receive-only mode to two full duplex, 10 Gig links

occur, and some of the flows may be split, i.e. the upstream packets of the flow go on one link, and the
downstream packets go on the other link.
When installed in this topology, the Cisco SCE 8000 completely overcomes this phenomenon, and
provides its normal monitoring functionality as if asymmetrical routing were not occurring in the two
links.
This installation supports monitoring functionality only, and is configured as "receive-only" connection
mode.

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.
