Chapter 6 Cabling the Line Ports and Completing the Installation

Cascaded Systems

Step 9 Connect the traffic port of Cisco SCE8000 platform #2. 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.)

Step 10 When full control is needed, change the link mode on both Cisco SCE8000 platforms on both links to ‘forwarding’. It is recommended to first configure the active Cisco SCE8000 platform and then the standby. (See How to Set the Link Mode, page 6-17.)

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

CLI Commands for Cascaded Systems

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 0 connection-mode

show interface linecard 0 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 platforms. Therefore the connection mode for both SCE platforms is:

Inline-cascade

Physically-connected-links— For each of the cascaded SCE platforms, this parameter defines the number of the link (Link 0 or Link 1) connected to this SCE platform.

Priority — For each of the cascaded SCE platforms, this parameter defines whether it is the primary or secondary device.

On-failure— For each of the cascaded SCE platforms, this parameter determines whether the system cuts the traffic or bypasses it via an external optical bypass module when the SCE platform either has failed or is booting.

If either the bypass or external-bypassoption is configured, the optical bypass module must be properly installed. If an optical bypass device is not detected, the command is executed but a warning is issued. The system then enters warning mode until either the command is changed, or the presence of an optical bypass device is detected

How to Configure the Connection Mode

Use the following command to configure the connection mode, including the following parameters:

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.
