NetFlow and NetFlowLite are both the same in reporting capabilities except that NetFlowLite is sampling based and is supported only by one reporting tool, which is nProbe To use NetFlowLite with other flow analyzer tools, you need an installation of nProbe which will convert NetFlowLite into traditional NetFlow before it can be processed.

Some of these include support for IPv4 and IPv6, Cisco NetFlow v9/IPFIX, NetFlowLite support, VoIP traffic analysis, flow and packet sampling, generating logs of web, MySQL/Oracle and DNS activity, and many more features The software is free if you download and compile on Linux or Windows. NetFlowlite (first introduced with Catalyst 4948E) bridges the gap by providing a lightweight solution that allows capturing of important flow information through packet sampling mechanisms combined with the extensibility of NetFlow version 9 and IPFIX. We shared some guides about the NetFlowlite/NFLite before, such as the Cisco Catalyst 4948E NetFlowlite/NFLite in Detail (first introduced with Catalyst 4948E), How to Use nProbe as NetFlowLite Aggregator/Collector?.

NetFlowLite on the Cisco Catalyst 2960X, 2960XR, 2960CX, and 3560CX Series Switches have the following capabilities NetFlowLite is supported on all downlink and uplink ports NetFlowLite is natively available with no additional hardware required The sampling range is from 132 to The application measures 16,000 flows per switch. Scrutinizer NetFlow Monitor is demonstrating the integrated view of NetFlow data from N7k and NetFlowlite from the 4948E Luca Deri, the developer of the nprobe and Cisco have been kind enough to let our NetFlow developers work directly with them to ensure our compatibility with the new NetFlow exports.

NetFlowLite Plugin¶ This plugin collects NetFlowLite flows and uses them as (simulated) packets as if they where received from a captured device As the plugin acts as a collector for flows sent in NFLite format, you need to specify the listening port and an optional number of sequential ports to which flows will be sent. NetFlow versions 5 and 9 are supported Any router that supports NetFlow data analysis may be used for this, but it is recommended to use the router that is functioning as the gateway from your network to the Internet The plan is to gradually increment the use of data collected from NetFlow in a whole range of UISP features. Configure NetFlow export Run the following command Replace AuvikCollectorIP with the IP address of your Auvik collector and AuvikPort with one of the following ports 55, 56, 4432, 4739, 6343, 9995 or 9996 configure set system flowaccounting interface # Optional parameter if flows should be collected for egress traffic set.

NetFlowLite The 2960x uses stream sampling without any form of packet capture There are two types of NetFlow Lite sampling configurations available on the 2960x Deterministic sampling;. The NetFlow Lite collect commands are used to configure nonkey fields for the flow monitor record and to enable capturing the values in the fields for the flow created with the record The values in nonkey fields are added to flows to provide additional information about the traffic in the flows A change in the value of a nonkey field does not. Deterministic sampling Deterministic samplers sample packets exactly as specified (ie, the first stream out of 100 streams).

Netflowlite monitor 1 !define a netflowlite monitor sampler check !tie the sampler “check” to monitor 1 exporter check !tie the exporter “check” to monitor 1 Once you are exporting the above samples in flows, most companies will need a converter to convert the sampled packet flows to traditional NetFlow or IPFIX. Deterministic sampling Deterministic samplers sample packets exactly as specified (ie, the first stream out of 100 streams).

Standard Netflow and Flexible Netflow options are available.

NetFlow Lite Overview NetFlow Lite uses flows to provide statistics for accounting, network monitoring, and network planning A flow is a unidirectional stream of packets that arrives on a source interface and has the same values for the keys A key is an identified value for a field within the packet. We shared some guides about the NetFlowlite/NFLite before, such as the Cisco Catalyst 4948E NetFlowlite/NFLite in Detail (first introduced with Catalyst 4948E), How to Use nProbe as NetFlowLite Aggregator/Collector?. The second goal is to explain how to configure the 2960X NetFlowLite Support The Cisco Catalyst 2960X NetFlowLite configuration is pretty straight forward however it is very different from the IPFIX PSAMP “NetFlowLite” we configured on the Cisco 4948E NetFlowLite The 2960x uses flow sampling without any form of packet capture.

NetFlow is a network protocol developed by Cisco that notes and reports on all IP conversations passing through an interface NetFlow is stateful and works in terms of the abstraction called a flow that is, a sequence of packets that constitutes a conversation between a source and a destination, analogous to a call or connection A NetFlow exporter device collects data on the IP traffic. Network traffic flow monitoring is the ability to collect IP network traffic as it enters or exits an interface LogicMonitor can monitor network traffic flow data for any devices that support common flow export protocols Specifically, LogicMonitor Collectors are configured to receive and analyze exported flow statistics for a device. The Free NetFlow Traffic Analyzer from SolarWinds is one of the more popular tools available to download free This tool allows you to sort, graph, and display data in various ways that allow you to visualize and analyze your network traffic.

We are going to be upgrading to 2960X at some point, which support Netflow Lite, so I'll probably just wait Thanks 0 Helpful Reply Post Reply Latest Contents Top of rack switch selection RJ45, Cat9k or Nexus Created by carl_townshend on 0121 AM 1 0 1 0. Netflowlite A basic packet sampling Netflow based implementation Exporter A device (for example, a router or a switch) with Netflow services enabled The exporter monitors packets entering an observation point and creates flows out of these packets. NetFlowLite collects packets randomly, classifies them into flows, and measures flow statistics as they pass through the switch It is a true flowbased trafficmonitoring mechanism that conserves valuable forwarding bandwidth when exporting flowbased data for analysis and reporting.
