General

Q. What is Cisco ® NetFlow Collector (NFC) 6.0?
A. Cisco NFC 6.0 is a NetFlow data collection and aggregation tool that provides a centralized view for data analysis and reporting. Cisco NFC empowers enterprises and service providers with actionable intelligence to optimize their network infrastructure for application delivery and network capacity planning. In addition, Cisco NFC is a critical enabler for business support applications such as usage-based billing and service-level objective (SLO) monitoring. Cisco NFC delivers industry-leading performance in helping enable network engineers to cope with the high-volume flow data typical in large networks.
Q. What are the differences between Cisco CNS NetFlow Collection Engine 5.0.3 and Cisco NetFlow Collector 6.0?
A. In addition to the change in name from Cisco CNS NetFlow Collection Engine (NFC 5.0.3) to Cisco NetFlow Collector (NFC 6.0), the version 6 implements a scalable multitier architecture for collecting, normalizing, correlating, and aggregating data from NetFlow-enabled devices dispersed across geographically distributed networks. The architecture comprises two layers: Cisco NFC as the first tier and Cisco Multi-NFC (MNFC) as the new tier-two component. Cisco MNFC adds network-level correlation and time-based summarization providing a central view for all distributed Cisco NFC implementations in the network. It provides end-to-end visibility across different parts of the network. In other words, while Cisco NFC provides a close-up view of the part of the network it monitors, Cisco MNFC provides a high-level, networkwide view by collecting data from across many such NetFlow collectors. All traffic summarization and configuration information is delivered through an advanced user-friendly Web interface. Typically, Cisco MNFC is deployed at the administrative control point of the network as illustrated in Figure 1.
Cisco NFC 6.0 is the replacement for Cisco NFC 5.0. Cisco NFC 6.0 is unmatched in handling a large number of unique flows (unique flows per second), while simultaneously aggregating granular data (1 minute aggregation period) from multiple aggregation schemes (key/value combinations). In addition to supporting a large selection of predefined aggregation schemes, Cisco NFC offers the flexibility for users to define their own aggregation schemes.

Figure 1. Customer Deployment Scenarios

Q. The customer has Cisco NFC 5.0.3 or an older version of Cisco NFC. How does the customer upgrade to Cisco NFC 6.0? Does the customer need to buy Cisco MNFC 6.0?
A. Cisco NFC 6.0 can be installed on a fresh server or on a server that is running Cisco NFC 5.0.x. In the latter case, the installation process detects the older version of software and upgrades the necessary components. Cisco NFC 6.0 includes all features in Cisco NFC 5.0.x and adds new features and functionality.
Cisco NFC and Cisco MNFC are companion products. Cisco NFC 6.0 runs as a standalone product and does not require Cisco MNFC. However, if you wish to enjoy the benefits of the tiered architecture, you can purchase Cisco MNFC and easily configure your Cisco NFC servers to send traffic to Cisco MNFC for end-to-end network visibility.
For more information about the features and benefits of Cisco MNFC 6.0, see the product datasheet at http://www.cisco.com/en/US/products/sw/netmgtsw/ps1964/index.html.
Cisco MNFC 6.0 does not work with Cisco NFC 5.0.3. Cisco MNFC supports only Cisco NFC 6.0.
Q. Do Cisco NFC 6.0 (tier one) and Cisco MNFC 6.0 (tier two) run on the same server?
A. No. Cisco NFC 6.0 and Cisco MNFC 6.0 run on separate servers. Refer to the server system configuration in the Installation and Configuration Guide at http://www.cisco.com/en/US/products/sw/netmgtsw/ps1964/prod_installation_guides_list.html for more information.
Q. How are Cisco NFC 6.0 and Cisco MNFC used?
A. Cisco NFC 6.0 is a major release and it replaces Cisco NFC 5.x. Furthermore, it provides enhanced value-added features, high performance, and scalability. Cisco MNFC 6.0 is a tier-two module. In other words, in the tiered hierarchy presented in Figure 1, Cisco MNFC resides at tier 2. It collects and summarizes traffic from tier 1 NetFlow collectors to provide an end-to-end network-level traffic analysis and a centralized view of all Cisco NFC 6.0 implementations.
Q. What features do Cisco NFC 6.0 and Cisco MNFC 6.0 provide?
A. A summary of the key features of Cisco NFC 6.0 can be obtained from the Cisco NFC 6.0 data sheet: http://www.cisco.com/en/US/prod/collateral/netmgtsw/ps6504/ps1964/product_data_sheet0900aecd806226bd.html.
Q. What hardware platform is required to run Cisco NFC 6.0 and Cisco MNFC 6.0?
A. Cisco NFC 6.0 supports the following operating systems and platforms:

• Solaris 8, Solaris 9, and Solaris 10 on an entry-level server with dual 1 GHz or greater SPARC processors, such as a Sun Fire V240

• Red Hat Enterprise Linux 2.1, 3.0, 4.0 (ES or AS)

• Minimum: 1 GB RAM, 10K SCSI, 30 GB hard disk, single processor on an entry-level server

• Recommended: 4 GB RAM, 15K Ultra 320 SCSI, dual 70 GB hard disks, dual processors on an entry-level server

Cisco Multi-NFC supports the following operating systems and platforms:

• Solaris 8, Solaris 9, and Solaris 10 on a midrange server, such as the Sun Fire T2000 with 1 GHz or greater UltraSPARC T1 processors

• Red Hat Enterprise Linux 2.1, 3.0, 4.0 (ES or AS) on a midrange server, such as an IBM x460 with 3.3 GHz or greater Intel Xeon processors

Refer to the Installation and Configuration Guide at http://www.cisco.com/en/US/products/sw/netmgtsw/ps1964/prod_installation_guides_list.html for details.
Q. How do I get an evaluation copy of Cisco NFC 6.0 and Cisco MNFC 6.0?
A. You can download an evaluation version of Cisco NFC 6.0 and Cisco MNFC 6.0 at http://www.cisco.com/cgi-bin/tablebuild.pl/nfcollector-3des.
Q. How do I get more information about Cisco NFC 6.0 and Cisco MNFC 6.0?
Q. Do Cisco NFC 6.0 and Cisco MNFC 6.0 require licenses?
A. Yes. Cisco NFC 6.0 and Cisco MNFC 6.0 support the FlexLM license. The customer pays a license fee per copy of Cisco NFC 6.0 per server. The license is node-locked to a server using the IP address of the server. Therefore, the server's IP addresses must be provided to obtain a license.
