Dual Link: Single Cisco SCE 8000 Topologies

In this topology, one Cisco SCE 8000 is connected to two full duplex, 10 GBE links. The Cisco SCE
8000 may be either inline, to support both monitoring and traffic control functionality, or receive-only
for traffic monitoring functionality only.

Receive-only topologies can be implemented using either an optical splitter or a switch. If a switch is

used, it must support SPAN functionality that includes separation between ingress and egress traffic and
multiple SPAN-ports destinations.

Dual Link: Two Cisco SCE 8000s Topology

In this topology, two Cisco SCE 8000s are connected to two full duplex, 10 GBE links, providing full
redundancy through cascading the two Cisco SCE 8000s. The Cisco SCE 8000s must be inline.
Note When installing a cascaded system, it is extremely important to follow the sequence of procedures
outlined in the
When two Cisco SCE 8000s are used, the ports 3/0/0 and 3/1/0 in each Cisco SCE 8000 are connected
to the links, whereas ports 3/2/0 and 3/3/0 are the cascade ports that are used for communicating between
the two Cisco SCE 8000s as follows:

Port 3/1/0: Link 0, Split of optic signal transmitted by network side
SPA modules 0 and 1 are connected to the first link (Link 0).
SPA modules 2 and 3 are connected to the second link (Link 1).
Dual link inline topologies require both Receive and Transmit fibers.
Dual link receive-only topologies use only Receive fibers.
To maintain link continuity at all times on both links when using the inline topology, two optical
bypass modules should be installed.
