Chapter 6 Cabling the Line Ports and Completing the Installation

Installing a Cascaded System

To configure the connection mode:

Step 1 From the SCE 2000(config if)# prompt, type connection-modeinline- cascade/receive-only-cascade[physically-connected-links{link-0/link-1}][priority {primary/secondary}] [on-failure{bypass/cutoff}] and press Enter.

EXAMPLE 1

Use the following command to configure the primary SCE 2000 platform in a two-SCE 2000 platform inline topology. Link 1 is connected to this SCE 2000 platform and the behavior of the SCE 2000 platform if a failure occurs is bypass.

SCE 2000(config if)# connection-mode inline-cascade physically-connected-links link-1 priority primary on-failure bypass

EXAMPLE 2

Use the following command to configure the SCE 2000 platform that might be cascaded with the SCE 2000 platform in Example 1. This SCE 2000 platform would have to be the secondary SCE 2000 platform, and Link 0 would be connected to this SCE 2000 platform, since Link 1 was connected to the primary. The connection mode would be the same as the first, and the behavior of the SCE 2000 platform if a failure occurs is also bypass.

SCE 2000(config if)# connection-mode inline-cascade physically-connected-links link-0 priority secondary on-failure bypass

Link Mode

The SCE 2000 platform has an internal hardware card used to maintain the links even when the SCE 2000 platform fails. This hardware card has four possible modes of operation:

bypass

forwarding

cutoff

sniffing

Normally, the link mode is selected by the SCE 2000 platform software according to the configured connection-mode. However, the link-modecommand can be used to enforce a specific desired mode. This may be useful when debugging the network, or in cases where we would like the SCE 2000 platform just to forward the traffic. (Note that this is only relevant to inline topologies even though the configuration is available also when in receive-only mode.)

The following link mode options are available:

Forwarding: forwards traffic on the specified link to the SCE 2000 platform for processing.

Bypass: stops all forwarding of traffic on the specified link to the SCE 2000 platform. Traffic still flows on the link, but is not processed in any way by the SCE 2000 platform.

This does not affect the redundancy states.

SCE 2000 4xGBE specifications

The Cisco Systems SCE 2000 4xGBE is a robust solution designed to optimize IP networks and enhance service delivery. As a member of Cisco's Service Control Engine (SCE) product line, this device is particularly suited for service providers looking to manage network traffic, improve service quality, and provide a suite of advanced management features.

One of the standout features of the SCE 2000 is its ability to process and analyze network traffic in real-time. This capability allows operators to gain insights into user behavior, application usage, and overall network performance. By utilizing deep packet inspection technology, the SCE 2000 can identify different types of traffic, enabling network managers to enforce policies and prioritize critical applications effectively.

In terms of interface capabilities, the SCE 2000 offers four 1 Gigabit Ethernet (GbE) ports. This versatility allows for easy integration into existing network infrastructure while ensuring ample bandwidth for data transfer. The device supports both IPv4 and IPv6 protocols, making it future-proof and suitable for evolving network demands.

One of the significant technologies employed by the SCE 2000 is Service Level Agreement (SLA) management. This feature ensures that service providers can meet their commitments to customers by monitoring performance metrics such as latency, jitter, and packet loss. The ability to generate reports based on SLA compliance allows for better customer engagement and transparency.

Additionally, the SCE 2000 facilitates dynamic resource allocation, enabling service providers to adapt network resources based on current demand. This elasticity is crucial in managing peak loads and ensuring a seamless user experience. Furthermore, the device’s support for Quality of Service (QoS) policies ensures that critical applications receive the necessary bandwidth and resources dedicated to maintaining operational efficiency.

The SCE 2000 also emphasizes security with features such as intrusion detection and prevention capabilities, helping protect the integrity of the network. This combination of performance monitoring, traffic management, and security makes the SCE 2000 an invaluable tool for service providers.

In conclusion, the Cisco Systems SCE 2000 4xGBE is a powerful network management solution that excels in providing real-time traffic management, SLA compliance, and security features. Its capabilities make it an essential component for service providers aiming to optimize their networks while delivering high-quality services to their customers.
