Q. What is CiscoWorks Network Compliance Manager (NCM) 1.2?
A. CiscoWorks NCM 1.2 is the third release of a new Web-based network management application in the CiscoWorks product family. It 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. CiscoWorks NCM helps IT staff identify and correct trends that could lead to problems such as network instability and service interruption.
Q. What enterprise network management problem does CiscoWorks NCM address?
A. Many network managers need comprehensive capabilities to automate the management of device configurations across their entire network from a central location while ensuring compliance with regulatory and business policies, corporate/IT directives, and technology best practices. This problem space is commonly referred to as network configuration and change management (NCCM).
Q. Why is Cisco
® releasing an NCCM product?
A. Many enterprise customers have indicated that they require NCCM functions efficiently integrated with the rest of their Cisco configuration management tools. CiscoWorks NCM addresses this requirement today while opening the door for increasingly sophisticated integration.
Q. Who should deploy CiscoWorks NCM?
A. Enterprises and service providers requiring scalable NCCM capabilities that include advanced workflow definition, a robust scripting interface, and the ability to maintain a multivendor network in compliance with regulatory policies, corporate IT methodologies, or technology best practices will find great value in CiscoWorks NCM.
Q. How does CiscoWorks NCM help users meet regulatory compliance goals and enforce internal IT best practices?
A. CiscoWorks NCM helps users meet regulatory compliance goals-such as the Visa Cardholder Information Security Program (CISP), Health Insurance Portability and Accountability Act (HIPAA), Gramm-Leach-Bliley Act of 1999 (GLBA), Sarbanes-Oxley (SOX) Act, and Information Technology Infrastructure Library (ITIL)-in several ways:
• It tracks all changes to the network-configuration, software, and hardware changes-in real time and captures them in a detailed audit trail.
• It screens all changes against authorized policies immediately to verify that they comply with regulatory requirements or IT best practices.
• It automatically validates new changes against appropriate policies before they are pushed to the network. If the changes are not compliant, CiscoWorks NCM does not allow them to be deployed.
• It automates the change review process, closing the gap between the approval of a change and the actual configuration change that is pushed to the network.
• It allows managers to enforce the approval of a change through a flexible, integrated approval model, using the exact configuration code that will be pushed to the network. Approvers of a change can review the change in the context of the entire device configuration and the business units it will affect. Event notifications are sent to interested parties, giving network staff immediate visibility into unplanned and unauthorized changes.
• It limits network configuration information to users on a need-to-know basis. CiscoWorks NCM uses highly customizable role-based permissions to control what information a user can view, what actions a user can perform on devices, and which devices a user can gain direct access to.
• It ships with regulatory reports for SOX, HIPAA, GLBA, and CISP enabled, providing the detailed metrics required by each of these regulations and providing the network information necessary to prove compliance.

Q. How does CiscoWorks NCM fit with Cisco Security Manager?
A. CiscoWorks NCM helps improve the security of network configurations and control of user access to view, deploy, or change device configurations. Cisco Security Manager is highly optimized for configuration management of security services such as firewalls, VPN devices, and intrusion protection systems (IPSs) on Cisco network devices. As such it offers an enhanced level of efficiency and ease of use when configuring security services on Cisco security devices. The audit and compliance-management features of CiscoWorks NCM greatly complement Cisco Security Manager because security-related configurations are especially important to audit.
Q. How does CiscoWorks NCM work with Cisco CAS?
A. CiscoWorks NCM provides the ability to deploy configurations across the enterprise network and is well suited to serve as an up-to-date configuration data source for modeling and impact analysis purposes. Cisco CAS automatically performs network-level consistency checks that identify misconfigurations, policy violations, inefficiencies, security gaps, and resiliency problems. Cisco CAS analyzes and validates network-level consistency by executing rules that audit the entire network, checking security vulnerabilities, IP addressing, route maps and attributes (such as QoS), regulatory compliance, and a wide variety of switching and routing protocols. Cisco CAS allows for scheduled or event-based automated data import on configuration changes from CiscoWorks NCM and then automatically generates a model of the network for high-performance analysis.
Q. Can CiscoWorks NCM use device inventory data stored in CiscoWorks DCR?
A. Yes. CiscoWorks NCM can automatically discover the devices available in the enterprise network. Additionally, device inventory can be imported into CiscoWorks NCM from CiscoWorks DCR, helping ensure consistency between the two CiscoWorks products.
Q. Can CiscoWorks NCM be launched from within another CiscoWorks application?
A. Yes. CiscoWorks NCM can be launched from CiscoWorks Home Page.
Q. Conversely, can CiscoWorks applications be accessed through CiscoWorks NCM?
A. Yes. For example, CiscoWorks Home Page, CiscoWorks Device Center, and CiscoView can be viewed by clicking in the appropriate CiscoWorks NCM menus.
Q. My network is large and will soon exceed a thousand nodes to be managed. How can I help ensure that my CiscoWorks NCM deployment is highly available?
A. CiscoWorks NCM is designed for fairly large-scale network deployments (up to tens of thousands of managed nodes) thanks to robust features such as data redundancy and high availability. For customers concerned about high availability due to the critical nature of NCCM, CiscoWorks NCM can be deployed in (optional) high-availability server configurations.
Q. What high-availability deployment options are supported in CiscoWorks NCM?
A. High Availability and Satellite deployment options provide a robust deployment architecture:
• High Availability enables visibility and control across the entire globally distributed network environment, automatically replicating information about the environment to multiple locations and dramatically reducing time to recover from failure by enabling immediate re-creation of the environment in a new location. It also allows IT organizations to extend best practices and knowledge across multiple locations and help achieve operational consistency across the enterprise.
• Satellite enables central management of network devices in remote locations and enables failover due to network instability across Network Address Translation (NAT) boundaries.
Q. Which types of network devices are supported by CiscoWorks NCM?
A. CiscoWorks NCM supports an extensive range of Cisco equipment plus devices from 35 other vendors. Categories include routers, switches, firewalls, wireless access points, VPN devices, network accelerators, network load balancers, and other appliances that serve dedicated functions such as terminal and proxy servers. CiscoWorks NCM can be easily upgraded to support new devices as they become available or to meet market demand.
Q. How is CiscoWorks NCM licensed?
A. The software is licensed on the basis of the number of nodes to be managed and whether the High Availability and Satellite features are enabled. Customers must purchase a software license for the core server, software licenses for the High Availability and Satellite features (if required), software licenses for the connectors with third-party software (if required), and the appropriate core and high-availability node count increments for the desired count of managed nodes..
Q. What is considered a managed node for licensing purposes?
A. A managed node is a management IP address and the configuration details for the system accessed by the management IP address. In most cases, a single device is equivalent to a single node. In more complex cases, such as a Cisco Catalyst Switch in hybrid mode, where the device is running as two separate configurations, each configuration is counted as a managed node. This is because in hybrid mode, the switch has two management IP addresses and two configuration files.
Q. For licensing purposes, are unmanaged nodes counted toward my licensed total node count?
A. No. Nodes that are unmanaged in CiscoWorks NCM are not counted toward the total licensed node count. For example, if your license is for 5000 nodes and you have 5100 nodes in CiscoWorks NCM but 100 nodes are unmanaged, you do not exceed your license limit.
Q. What server operating systems does CiscoWorks NCM support?
A. CiscoWorks NCM is available on the following platforms:
• Microsoft Windows Server 2000 or 2003 Enterprise Edition
• Linux RedHat ES/AS 3UP2/4
• SUSE Linux Enterprise Server 9
• Sun Solaris 9
• Sun Solaris 10
Q. What database management systems does CiscoWorks NCM support?
A. CiscoWorks NCM supports the following database management systems:
• Microsoft SQL Server 2000
• Microsoft SQL Server 2005
• Oracle 9i
• Oracle 10g
• MySQL 3.23
Q. Should CiscoWorks NCM be installed on its own dedicated server?
A. In CiscoWorks NCM 1.0, users were restricted to installing NCM on a dedicated server to avoid port access conflict for HTTP, HTTPS, Telnet, syslog, and other functions. This restriction has been removed since CiscoWorks NCM 1.1. Users can now install NCM and LMS on the same server (Windows version only).
Q. How do I prepare my network for the deployment of CiscoWorks NCM?
A. CiscoWorks NCM communicates with devices using a combination of protocols and ports. Please refer to the CiscoWorks NCM installation checklist in the Get Started Guide for detailed information on preparing your network for CiscoWorks NCM deployment.
