Dual Link: Two SCE 2000s Topology

In this topology, two SCE 2000s are connected to two full duplex, GBE links, providing full redundancy through cascading the two SCE 2000s. The SCE 2000s may be either inline, to support both monitoring and traffic control functionality, or receive-only for traffic monitoring functionality only.

Note When installing a cascaded system, it is extremely important to follow the sequence of procedures outlined in the section Installing a Cascaded System (on page 6-12).

Note 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.

When two SCE 2000s are used, the first two ports in each SCE 2000 are connected to the links, while ports 3 and 4 are the cascade ports that are used for communicating between the two SCE

2000s as follows:

SCE 2000 #1

•Port 1: Link 1, Subscribers side

•Port 2: Link 1, Network side

•Port 3: Cascade, connect to Port 4 in SCE 2000 #2

•Port 4: Cascade, connect to Port 3 in SCE 2000 #2

SCE 2000 #2

•Port 1: Link 2, Subscribers side

•Port 2: Link 2, Network side

•Port 3: Cascade, connect to Port 4 in SCE 2000 #1

•Port 4: Cascade, connect to Port 3 in SCE 2000 #1
