CiscoWorks Network Compliance Manager (NCM) tracks and regulates configuration and software changes throughout a multivendor network infrastructure. It provides superior visibility into network changes and can track compliance with a broad variety of regulatory, IT, corporate governance, and technology requirements. NCM helps IT staff identify and correct trends that could lead to problems such as network instability and service interruption.
Enterprises seeking to facilitate high performance business applications increasingly rely on sophisticated networking infrastructure and the power of new technologies. Network operations and security managers rely on systems that can automate network deployments, handle large and complex topologies, and track and audit how actual network deployments comply with design requirements and best practices. Enterprise networks must comply with regulatory policies, corporate IT methodologies, and technology best practices-independently of scale, networking technologies deployed, and the combination of vendors providing networking equipment. NCM helps users meet regulatory compliance goals and enforce internal IT best practices.
Network Lifecycle Automation
NCM automates the complete operational lifecycle of network devices, which includes:
• Discover and track: Includes discovering and cataloging the network, visualizing the Layer 2 and Layer 3 network topology, initial device turn-up, and creating initial snapshots of device configurations
• Change and configure: Includes creating and deploying configuration changes in a structured manner, such as using configuration templates or scripts, peer reviewing and approving proposed changes, and maintaining an archive of previous configurations
• Audit and enforce: Includes defining compliance policies for your network devices, detecting violations in real time, and autoremediating problems.
• Maintain and support: Includes providing reports on device inventory, change activity, and compliance.
Enforce Policies, Standardize Operations, and Meet Compliance
Bringing networks into compliance with corporate or regulatory standards is a nontrivial, labor-intensive, error-prone, and difficult task. NCM helps you meet compliance standards through a network compliance model that maps device information, including configurations and run-time diagnostics, as well as policies and user roles, into a normalized structure to prevent compliance violations before they occur.
Built-in best practices immediately measure network compliance against industry-accepted best practices. NCM incorporates policies such as the National Security Agency (NSA) router configuration guidelines.
Predefined reports for Information Technology Infrastructure Library (ITIL), the Sarbanes-Oxley Act (SOX), the Health Insurance Portability and Accountability Act (HIPAA), the Payment Card Industry (PCI) standard, and other regulations offer immediate insight into network compliance. These reports provide the metrics that each of these regulations or processes requires, increasing visibility and saving auditors and network engineers time.
Prevent Network Downtime and Increase Stability
Peer reviews can reduce the number of configuration defects in a network. NCM automates peer reviews, ticketing, and approval processes to reduce the time between approving a configuration change and implementing it on your network.
New Features in CiscoWorks NCM 1.5
NCM 1.5 includes the following new features:
• Virtual device and virtual context support: NCM now provides support for virtual devices, including VMware's Virtual Switch (vSwitch) technology available through VMware's Infrastructure (ESX) and the Cisco® Nexus 1000v Series switches. These new virtual devices can be managed alongside legacy devices, providing centralized support. Virtual devices, as well as devices that support virtual contexts, now benefit from device relationship enhancements that provide management of non-IP addressed contexts, as well as views of the underlying relationships between the actual hardware and virtual contexts.
• Enhanced relationship modeling: Devices may have relationships with other devices or contained modules that run an independent operating system-complete with a full configuration and interfaces. NCM 1.5 distinguishes relationship types including both user-defined and system-defined relationships.
• Enhanced task scheduling: Two key task management features, task prioritization and round-robin execution of group tasks, have been implemented to improve the execution order of tasks.
• Enhanced Device Selector and Device Group Explorer: With the enhanced Device Selector and Device Group Explorer you can easily navigate group trees to select devices and device groups for a variety of use cases.
• Enhanced VLAN support: NCM now provides functionalities necessary to view fully and to provision VLANs on network switches from different vendors.
• Link aggregation support: Using link aggregation support, NCM can list all of the links (or connections) associated with a specific port on a device. This information is gleaned from enhanced diagnostics or from new device context information. Link aggregation lets you manage a device with virtual contexts that assign multiple connections to a physical port.
• Provisioning and scripting API enhancements: You can now list device templates, show device template configurations, modify device template configurations, and provision devices using the Device Relationships API.
• Solaris 64-bit support: When installing NCM on a Solaris platform, NCM uses the 64-bit Java Virtual Machine (JVM). As a result, NCM can utilize more memory and achieve enhanced scalability and performance.
• Caching improvements: Caching improvements increase performance of many functions across the NCM product. Minimizing redundant data lookups such as driver lookup and device lookup while using memory more efficiently on both 32-bit and 64-bit systems have been implemented.
• Driver-defined diagnostics: Driver-defined diagnostics allow drivers to specify the set of diagnostics that are "standard" for that driver and define new basic diagnostics that the system will treat as "built in." The ability to define "standard" diagnostics for a device will allow more up-to-date diagnostic implementations for any given device.
