CHAPTER 3 Topology This chapter describes the possible deployment topologies of the SCE 2000. The Cisco SCE solution offers a number of basic topology options that permit the user to tailor the SCE Platform to fit the needs of a particular installation. An understanding of the various issues and options is crucial to designing, deploying, and configuring the topology that best meets the requirements of the individual system.
Chapter 3 Topology Topology Considerations • Number of links — The SCE 2000 may be connected to one or two GBE links. This is relevant for both Inline and Receive-Only topologies. • Redundancy — Must the system be designed to guarantee uninterrupted SCE 2000 functionality? If so, there must be a backup SCE 2000 Platform to assume operation in case of failure of the primary device.
Chapter 3 Topology Topology Considerations Link Continuity The bypass mechanism of the SCE 2000 allows traffic to continue to flow, if desired, even if the device itself is not functioning. Note that when the SCE 2000 is connected to the network through an optical splitter, a failure of the SCE 2000 does not affect the traffic flow, as the traffic continues to flow through the optical splitter.
Chapter 3 Topology Physical Topologies Physical Topologies Following are descriptions of a number of physical topologies that the SCE 2000 supports. Single SCE 2000 Topologies A single SCE 2000 supports both single GBE link and dual GBE link topologies. Single Link: Inline Topology Typically, the SCE 2000 is connected in a full duplex GBE link between two devices (Router, BRAS, etc.).
Chapter 3 Topology Physical Topologies Dual link: Inline Installation In this topology, one SCE 2000 is connected inline in two full duplex, GBE links. In case the two links are load-shared, asymmetrical routing might 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.
Chapter 3 Topology Physical Topologies Single Link: Receive-only Topology In this topology, an optical splitter resides physically on the GBE link between the subscribers and the network. The traffic passes through the optical splitter, which splits traffic to the SCE 2000. The SCE 2000, therefore, only receives traffic and does not transmit.
Chapter 3 Topology Physical Topologies Dual Link: Receive-Only Topology In this topology, one SCE 2000 is connected in receive-only mode to two full duplex, GBE links using optical splitters. If the two links are load-shared, asymmetrical routing might 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.
Chapter 3 Topology Physical Topologies Two Cascaded SCE 2000s For Dual Links In this topology, two cascaded SCE 2000s are used. This allows a fail-over solution, where in case of a failure of one SCE 2000, the functionality that the SCE 2000 provides is preserved by the redundant platform. Two Cascaded SCE 2000s: Inline Topology This topology allows both control and monitoring functionality where redundancy is required and “inline” connection is used.
Chapter 3 Topology Physical Topologies • When one SCE 2000 fails (depending on the type of failure) its link traffic is still bypassed to the functioning SCE 2000 and processed there, so the traffic processing continues for both the links. • The bypass of the traffic through the failed SCE 2000 is configurable, and the user may choose to always cutoff the line that goes through the failed SCE 2000.
Chapter 3 Topology Physical Topologies • Receive-only — The SCE 2000 does not reside physically on the data link. Data is forwarded to the SCE 2000 via an external switch. The SCE 2000 itself receives only and does not transmit. Cascade — Indicates a two SCE 2000 topology where the SCE 2000s are connected via the cascade ports. • The connection mode parameter is determined by the physical deployment of the SCE 2000, as follows: • Single SCE 2000 inline installation = “Inline” connection mode.
Chapter 3 Topology Physical Topologies • Non-redundant inline topology if value-added services are crucial and are more important than maintaining connectivity. Bypass mode is required for the following: • • Non-redundant inline topology if connectivity is crucial.

CHAPTER 6 Cabling the Line Ports and Completing the Installation This chapter provides instructions for cabling the Gigabit Ethernet ports for both one and two SCE 2000 topologies, and for configuring Gigabit Ethernet (GBE) interface parameters. In a topology utilizing two SCE 2000s (cascade), this includes the cascade ports as well as the line ports.
Chapter 6 Cabling the Line Ports and Completing the Installation Connecting the line ports to the network Testing Connectivity: Examining Link LEDs, GBE Counters ("Testing Connectivity: Examining Link LEDs and Counters" on page 6-9) • Cabling Diagrams Before beginning, find the appropriate cabling diagram for the topology in your installation: Single SCE 2000 topologies • • Single Link: Inline Topology (on page 6-2) • Single Link: Receive-only Topology (on page 6-3) • Dual Link: Single SCE 2000 T
Chapter 6 Cabling the Line Ports and Completing the Installation Connecting the line ports to the network Single Link: Receive-only Topology In this topology, an optical splitter resides physically on the GBE link that the SCE 2000 should monitor. The optical splitter is connected to the SCE 2000 via Rx links only. In this topology, the traffic passes through the optical splitter, which splits traffic to the SCE 2000. Note Receive-only topologies can also be implemented using a switch.
Chapter 6 Cabling the Line Ports and Completing the Installation Connecting the line ports to the network As with the single link cabling, inline topologies require both Receive and Transmit fibers, while Receive-only systems use only Receive fibers. 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.
Chapter 6 Cabling the Line Ports and Completing the Installation Connecting the line ports to the network 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.
