Chapter 6 Cabling the Line Ports and Completing the Installation

Installing a Cascaded System

Step 2 Connect both SCE 2000 platforms to the management station. (See Connecting the Management Interface (on page 5-25).)

Step 3 Connect the cascade ports. (See Dual Link: Two SCE 2000s Topology (on page 6-5).)

Step 4 Set topology configurations for each SCE 2000 platform via the connection-mode options. (See Topology-Related Parameters for Redundant Topologies (on page 6-11).)

Step 5 Make sure that the SCE 2000 platforms have synchronized and active SCE 2000 platform was selected.

Use the show interface linecard 0 connection-mode command.

Step 6 If you want to start with bypass/sniffing, change the link mode to your required mode in both SCE 2000 platforms on both links. The bypass mode will be applied only to the active SCE 2000 platform. (See Link Mode (on page 6-13).)

Step 7 Make sure that the link mode is as you required. (See Monitoring the System (on page 6-14).)

Use the show interface linecard 0 link mode command.

Step 8 Connect the traffic port of SCE 2000 platform #1. This will cause a momentary down time until the network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working (when working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-5).)

Step 9 Connect the traffic port of SCE 2000 platform #2, this will cause a momentary down time until the network elements from both sides of the SCE 2000 platform auto-negotiate with it and start working (when working inline). (See Dual Link: Two SCE 2000s Topology (on page 6-5).)

Step 10 When full control is needed, change the link mode on both SCE 2000 platforms on both links to ‘forwarding’. It is recommended to first configure the active SCE 2000 platform and then the standby. (See Link Mode (on page 6-13).)

Step 11 You can now start working with the Subscriber Manager.

CLI Commands

This section presents CLI commands relevant to the configuration and monitoring of a redundant system.

Use the following commands to configure and monitor a redundant system:

•connection-mode

•[no] force failure-condition

•Show interface linecard 'number' connection-mode

•Show interface linecard 'number' physically-connected links

Topology-Related Parameters for Redundant Topologies

All four of the topology-related parameters are required when configuring a redundant topology.

•Connection mode — Redundancy is achieved by cascading two SCE 2000 platforms. Therefore the connection mode for both SCE 2000 platforms may be either:

•Inline-cascade

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.
