Effectively Manage and Control the
Hybrid Fiber-Coaxial Network
with Cisco Cable Manager

Cisco Cable Manager provides a graphical, client- server application that simplifies the monitoring and troubleshooting of a hybrid fiber-coaxial (HFC) cable network. Cisco Cable Manager lets operators easily manage Cisco cable modem termination system (CMTS) products, as well as Cisco and third-party cable modems that are compliant with Data-over-Cable Service Interface Specifications (DOCSIS) or EuroDOCSIS. Based on the highly scalable Cisco Element Management Framework (Cisco EMF), Cisco Cable Manager integrates CiscoView, Cisco Cable Troubleshooter, and Cisco DOCSIS CPE Configurator into its product offering.

Introduction

Today, demand for advanced cable services is changing the landscape of the cable market. "Always-on" broadband cable allows consumers to change the way they communicate. Cable service providers can deploy with confidence new applications such as voice over IP (VoIP) and virtual private networks (VPNs).

With the introduction of new markets comes the challenge of managing the cable infrastructure that delivers these services. Effective network management requires monitoring and managing all aspects of the infrastructure, including the ability to build a composite view of components that make up the service.

Cable service providers need tools to deploy, maintain, troubleshoot, and monitor HFC network equipment. Tools must offer flexibility to support a rapidly changing environment where network configuration can change quickly to incorporate newer technology. The management framework must scale as the network grows. Network reliability is a central concern. Tools must deliver comprehensive yet easy-to- understand information that allows operators to detect and solve network problems quickly. Proactive network management is needed to ensure that problems do not escalate into more serious outages affecting the availability and performance of critical services.

Product Description

Cisco Cable Manager is a graphical, client-server application that supports proactive surveillance and maintenance of the HFC network. Together, with the bundled applications, Cisco Cable Manager allows operators to perform:

Fault management—Detect and isolate faults with Cisco EMF Event Manager features, CiscoView chassis and cable modem views, and diagnostic capabilities

Configuration management—Track network and system configuration information with topology tree views, forms-based CMTS configuration, and software image download capability to cable modems

Performance management—Maintain overall performance of the network at an acceptable level with metrics, including options to specify polling groups and generate tabular and graphical historical performance reports

Security management—Control access to network resources, including device- and task-based partitioning

Cisco Cable Manager bundles:

CiscoView Version 4.2, which displays component views of Cisco CMTS and cable modem products, as well as DOCSIS- or EuroDOCSIS-compliant cable modems.

Cisco Cable Troubleshooter Release 1.3, which pinpoints radio frequency (RF) issues to automate analysis and interpretation of the Cisco patent-pending "flap list" maintained in Cisco CMTS products. The flap list helps isolate problems between the cable plant, such as ingress noise or incorrect power levels, and specific RF customer premises equipment (CPE) devices.

Cisco DOCSIS CPE Configurator Version 3.2, which automates the creation or editing of a DOCSIS or EuroDOCSIS cable modem configuration file.

Cisco EMF Version 3.1 serves as the foundation for the Cisco Cable Manager. Cisco EMF provides common interfaces and element management services across Cisco service provider products. This flexible, modular model lets cable operators install a mix of element managers today to meet current business needs yet accommodate future growth. Service providers can more rapidly deploy new element managers to manage new services.

Element managers are the applications that manage specific types of network devices. Element managers interact with users through graphical user interfaces (GUIs) and contain references to other managers in the set. Cisco EMF components include: Object Manager, Event Manager, Event Browser, Threshold Manager, Alarm Scoreboard, and Performance Manager. Cisco Cable Manager offers a Tools Launch Pad option to open CiscoView, Cisco Cable Troubleshooter, and Cisco DOCSIS CPE Configurator bundled applications.

Using Cisco Cable Manager, operators can build a model of the cable network using an object-oriented paradigm (Figure 1). An object is a building block within Cisco Cable Manager to model network elements. An object represents the element to be managed. Several objects can manage a network element. Each object within Cisco Cable Manager is a member of an associated object class. Objects exist within one or more hierarchical relationships, or containment trees. Cisco Cable Manager offers:

Object-oriented modeling to identify and represent resources within the managed space

Auto-discovery topology to automatically detect, model, and maintain an active inventory of managed objects

Monitoring to determine changes in topology or state

Interpretative intelligence to aid personnel in identifying and determining the "root cause" of problems

Comprehensive Fault Management for Increased Reliability

A rich suite of fault-management features in Cisco Cable Manager enables proactive surveillance of network status. Figure 5 provides a snapshot of the network alarm status.

Real-time fault alerts generated by cable components can be displayed, cleared, and color-coded based on severity. Cisco Cable Manager includes flexible options that support event filtering, as well as customizable event notifications that speed problem isolation and resolution.

Each node in the tree and each event are color-coded to indicate the severity of a propagated alarm. Cisco Cable Manager supports alarm filtering, clearing, and SNMP trap-forwarding capabilities. Flexible event notification is available through user-customizable scripts: for example, generating an e-mail message or a page.

Additional alarms can be generated when user-defined utilization and error threshold levels are exceeded. This allows proactive monitoring of potential problems. User-defined threshold levels may be based on raw SNMP attributes or on derived rate-based thresholds.

In addition, for quicker fault isolation, Cisco Cable Manager supports "ping" connectivity tests at the IP and MAC layers between the Cisco CMTS and the cable modem. Cisco Cable Manager offers template-based CMTS configuration to adjust parameters. Easy-to-use forms-based templates enable users to retrieve or set multiple parameters for the Cisco CMTS.
