How to Install a Cascaded System

This section outlines the installation procedures for a redundant solution with two cascaded Cisco SCE8000 platforms. Refer to the Cisco Service Control Engine (SCE) CLI Command Reference for details of the CLI commands.

When working with two Cisco SCE8000 platforms with split-flow and redundancy, it is extremely important to follow this installation procedure.

Step 1 Install both Cisco SCE8000 platforms, power them up, and perform the initial system configuration. (See Chapter 4, “Installing the Cisco SCE8000 Chassis”and Chapter 5, “Connecting the Management Interfaces”and Starting the Cisco SCE8000 Platform, page 7-1.)

To maintain link continuity at all times, including during the reload sequence and power failure events, optical bypass modules must be installed.

Step 2 Connect both Cisco SCE8000 platforms to the management station. (See Connecting the Management Interface, page 5-4.)

Step 3 Connect the cascade ports. (See Dual Link: Two Cisco SCE8000s Topology, page 6-3.)

The cascade ports must be either be connected directly in Layer 1 (dark fibers), or using the following procedure to connect through a switch.

Connect port 3/2/0 from box A and port 3/3/0 from box B to a single switch. Configure them both on the same access VLAN, which will be used only by the interfaces connected to these ports. No other interfaces in the switch should reside on that VLAN.

Connect port 3/3/0 from box A and port 3/2/0 of box B to a switch on a different VLAN. Again, the access ports should be configured as access ports on this VLAN, which will be used only by the interfaces connected to these ports. No other interfaces in the switch reside on the VLAN.

Step 4 Set topology configurations for each Cisco SCE8000 platform via the connection-mode options. (See How to Configure the Connection Mode, page 6-16.)

Step 5 Make sure that the Cisco SCE8000 platforms have synchronized and active Cisco SCE8000 platform was selected.

Use the show interface linecard 0 connection-mode command.

Step 6 If you want to start with bypass, change the link mode to your required mode in both Cisco SCE8000 platforms on both links. The bypass mode will be applied only to the active Cisco SCE8000 platform. (See How to Set the Link Mode, page 6-17.)

Step 7 Make sure that the link mode is as you required. (See Monitoring the System, page 6-18.)

Use the show interface linecard 0 link mode command.

Step 8 Connect the traffic port of Cisco SCE8000 platform #1. This will cause a momentary down time until the network elements from both sides of the Cisco SCE8000 platform auto-negotiate with it and start working (when working inline). (See Dual Link: Two Cisco SCE8000s Topology, page 6-3.)

SCE8000 specifications

Cisco Systems SCE8000 is an advanced service control edge solution designed to enhance the management and performance of service provider networks. Targeted at carriers and large enterprises, the SCE8000 is characterized by its capacity to efficiently handle traffic management, quality of service (QoS), and policy enforcement across various services including voice, video, and data.

One of the main features of the SCE8000 is its scalability. The platform supports a high-density architecture, allowing service providers to seamlessly expand their networks to accommodate growing traffic demands. This scalability is complemented by an impressive throughput, which enables the handling of millions of concurrent sessions, making it ideal for environments with significant user activity.

The SCE8000 employs advanced traffic management capabilities, leveraging deep packet inspection (DPI) technology. This allows for granular visibility into network traffic, enabling service providers to make informed decisions about resource allocation and policy application. Additionally, the device supports multiple protocol analysis, ensuring compatibility across various network services and enhancing overall efficiency.

Quality of Service (QoS) is another critical characteristic of the SCE8000. The platform provides sophisticated mechanisms to prioritize traffic, thereby ensuring that delay-sensitive applications such as VoIP and video streaming receive the necessary bandwidth. This capability is enhanced by Cisco's intelligent traffic shaping and congestion management features, which work together to optimize the user experience even in congested network conditions.

The SCE8000 also integrates robust security features, including session initiation protocol (SIP) security, to protect against malicious attacks and maintain service integrity. This is particularly important in today's cyber landscape where service providers must safeguard their infrastructure from various threats.

Automation and programmability are essential characteristics of the SCE8000, enabling operators to implement policies quickly and efficiently. This feature allows for dynamic scaling and rapid deployment of new services, significantly reducing the time to market for new offerings.

In conclusion, Cisco Systems SCE8000 stands out as a powerful platform for managing service provider networks. With its high scalability, advanced traffic management, quality of service assurance, robust security features, and automation capabilities, the SCE8000 enables service providers to deliver a superior customer experience while optimizing their operational efficiency. This makes it an invaluable asset for any organization looking to enhance its network performance and service delivery.
