Objective
About This Guide
The Cisco CNS NetFlow Collection Engine Installation and Configuration Guide, Release 5.0.2
describes the CNS NetFlow Collection Engine application, which is used with the NetFlow services data
export feature on Cisco routers and Catalyst 5000 and 6000 series switches. This document also
describes the system requirements that must be met to install the CNS NetFlow Collection Engine
product, as well as, how to install, start, and configure CNS NetFlow Collection Engine.
NetFlow services consist of high-performance IP switching features that capture a rich set of traffic
statistics exported from routers and switches while they perform their switching function. CNS NetFlow
Collection Engine provides fast, scalable, and economical data collection from multiple export devices
exporting NetFlow data records.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two types of support are available through the Cisco TAC: the Cisco Technical
Support Web Site and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration.
• Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably
impaired, but most business operations continue.
• Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects
of business operations. No workaround is available.
About This Guide
• Priority level 1 (P1)—Your production network is down, and a critical impact to business operations
will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of
service contracts, when applicable.
Cisco Technical Support Web Site
The Cisco Technical Support Web Site allows you to resolve P3 and P4 issues yourself, saving both cost
and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To
access the Cisco Technical Support Web Site, go to the following URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco services contract have complete access to
the technical support resources on the Cisco Technical Support Web Site. The Cisco Technical Support
Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not
have a login ID or password, go to the following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco Technical Support Web Site, and you are
a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the
following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco
Technical Support Web Site.

About This Guide
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority
level 2; these classifications are assigned when severe network degradation significantly impacts
business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC
engineer will automatically open a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following
URL:

Before calling, please check with your network operations center to determine the level of Cisco support
services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network
Supported Accounts (NSA). In addition, please have available your service agreement number and your
product serial number.
