Chapter 6 Cabling the Line Ports and Completing the Installation

Installing a Cascaded System

Sniffing: allows the SCE 2000 platform to forward traffic on the specified link through the bypass mechanism while still analyzing the traffic passively.

Sniffing is permitted to be configured for for all links, only (use the all-links option).

Cutoff: completely cuts off flow of traffic through the specified link.

Note the following recommendations and restrictions:

Since the SCE 1000 platform has only one link, the link is not specified.

Since the SCE 2000 platforms have more than one link, it is required to specify the link. The link designations are different for the GBE and FE platforms, as follows:

SCE 2000 4xGBE: GBE1-GBE2/GBE3-GBE4

SCE 2000 4/8xFE: LINK1/LINK2

Use the 'all-links'option to configure the link mode for all links (SCE 2000 platforms only).

It is recommended that both links be configured together. Use the all-links option.

Link mode is relevant only to inline topologies.

It is recommended that in cascaded topologies, both SCE 2000 platforms be configured for the same link mode, otherwise the service will be unpredictable.

Sniffing can only be configured for all links, therefore, to configure sniffing, the all-links option is required, not just recommended.

The default link mode is forwarding. When other link modes are selected, active service control is not available and any service control configuration will not be applicable.

To set the link mode:

Step 1 From the SCE 2000 (config if)# prompt, type link-mode [<link>all-

links] [forwardingbypasssniffingcutoff] and press Enter.

Monitoring the System

Use the following commands to view the current connection mode and link mode parameters. To view the current connection mode:

Step 1 From the SCE 2000# prompt, type show interface linecard 0 connection-mode and press Enter.

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.
