Meet the newest free tool in the SolarWinds portfolio: NetFlow Configurator! NetFlow traffic analysis has become an increasingly important factor when it comes to managing your network and keeping an eye on bandwidth utilization. So we designed a free tool that makes it easier than ever before to get started with Cisco NetFlow!

SolarWinds NetFlow Configurator is an easy-to-use tool for remotely and quickly configuring NetFlow v5 via SNMP on supported CiscoŽ devices. NetFlow Configurator also facilitates setting up collectors for Cisco NetFlow data, specifying the ports on which the collectors are listening, and enabling monitoring of inbound and outbound (ingress/egress) traffic data per interface.

NetFlow Configurator is just one of several SolarWinds applications that can aid you in performing NetFlow traffic analysis. Check out these other great NetFlow tools with FREE 30-day evaluations!

SolarWinds NetFlow Real-time Tool, which is included in our award-winning Engineer's Toolset, is a real-time capture and analysis tool that stores up to one hour of Cisco NetFlow data on a single router interface. It displays interface inbound and outbound traffic separately for granular analysis and troubleshooting.
Orion NetFlow Traffic Analyzer enables you to capture continuous streams of network traffic across multiple router interfaces and convert those raw numbers into easy-to-interpret charts and tables that reveal exactly how the corporate network is being used, by whom and for what purpose ? enabling you to shut down the bandwidth hogs.

A little tool to get and set SNMP standard data and individual data. Works on predefined MIB2 OIDs and self-defined OIDs. Maybe a little buggy but I just threw the code down and compiled it for use in one project.

WebNMS SNMP API offers a comprehensive development toolkit for SNMP-based network management applications. WebNMS's SNMP stack comprises a set of powerful Java SNMP library to build real-time applications for monitoring and tracking network elements that are reliable, scalable, and OS independent.The Java SNMP library provides off-the-shelf components for trap and table handling along with basic SNMP operations, such as SNMP GET, SNMP GETNEXT, SNMP GETBULK, and SNMP SET. These components enable simple and rapid development and deployment of SNMPv1, SNMPv2c, and SNMPv3 management applications.The SNMP management application (manager) built using the Java-based SNMP API can receive SNMP traps, which can be processed based on predefined criteria for effective SNMP management.
WebNMS SNMP API completely supports SNMPv3, as it is compliant with RFC 3411, 3412, 3413, 3414, and 3415. WebNMS SNMP API provides an elegant way of implementing the security and access controls. Users can also define and implement their own security and access control model. Default implementation of USM and VACM based security models are offered using these frameworks. Also, SNMP API has the provision to store the v3 configuration data in a database. This is particularly useful when managing large number of SNMPv3 devices via WebNMS SNMP API. It also supports co-existence, notification filtering, and proxy forwarding; thus confirming to the RFC 2573 and 2576.
SNMP API can be used with two-tier as well as three-tier management applications. In the two-tier architecture, the management applications directly communicate with the agents. In the three-tier architecture, the management applications communicate with the agents through a manager-server. For building highly scalable management applications, three-tier architecture is the best option.

How does it work and what does it do?
Simply enter the IP address of your switch and its SNMP read community in the
fields and press the Retrieve Table button to get the list. If it fails you will
be told.
Fdbget.exe is a little tool to retrieve entries from the forwarding database
of switches. It gives you a table of MAC to interface number. If you are
looking for a specific MAC on a switch then simply enter the MAC or part of it
into the search field (without regular expressions).
The table results and search results are exported to separate files.

Paessler Netflow Tester dumps the data of all Netflow packets that a computer receives from a Cisco router. This can be useful when debugging bandwidth monitoring configurations based on Cisco's Netflow protocol. First the Netflow protocol must be enabled and configured on the router. Then the router must be given the IP address of the computer running Netflow tester so that the UDP data packets with Netflow data are sent to that computer.

Just follow these simple instructions:

1) Download Paessler Netflow Tester and then start netflowtest.exe

2) Enter the IP and port number that you have configured as netflow packet target in your Cisco Router. Usually selecting "any IP" should work, in some cases the IP must be explicitly selected.

3) Enable "Start Netflow Collector".

4) You should now see a line in the logfile for each packet the computer receives. Each line shows the time, netflow version, number of flows and the IP of a packet (note: You need netflow version 5 for PRTG Traffic Grapher!)

5) Enable "Show Flow Data" to also show the corresponding flow data.

6) If you do not see any activity then the system does not receive any netflow data (e.g. due to misconfiguration of the router or a firewall blocking the packets, etc.)

With Paessler SNMP Tester you can run simple SNMP requests against a device in your network. During the test each single step of the SNMP request is logged into a logfile for analysis. The idea of this free program is to debug SNMP requests down to the protocol level in order to find communication and/or data problems in SNMP monitoring configurations.

Just follow these simple instructions:

1) Download Paessler SNMP Tester and run the snmptest.exe file.

2) Enter the IP address of your device and select the SNMP port and the SNMP community string.

3) Select a request type:
(a) MIB2 Interface: Reads the traffic counter of a port according to the MIB2 OID
(b) Custom OID: Enter a custom OID value to access any OID value on the device
(c) Device Uptime: Reads the standard system uptime value from the device

4) It may be necessary to select a specific local IP for the SNMP request (usually only necessary for multi homed systems)

5) Click on "Run Test" to start the testing process.

6) During the test you will find detailed information in the logfile window.

SNMP Test for routers is a tool that queries and monitors SNMP-compatible devices but it is especially designed to test SNMP router compatibility. The first part of the test queries the system name and system description strings, the forwarding flag and enumerates all the exposed interfaces. The 2nd part of the test monitors SNMP traps from the device (your system must be configured to receive traps from the device). While the monitoring is running, trigger some events e.g. connection and disconnection of the Internet line and see if those events are reported in the application.

What does it do and how does it work?
Inftraf is a tool that requests IN/OUT octet data (MIB2) from SNMP-capable
network interfaces. You can use this program in a professional network
environment to monitor selected network interfaces (even backplane ports
if the device provides the information) or you can monitor your home network
or cable/modem/ISDN connection to the internet. You can monitor bits/sec,
utilization and accumulated traffic.

Enter IP address and SNMP read community into the fields and click on FIRST
CONTACT. The program will then try to retrieve all interface information of
the device. If successful, this will enable the START POLLING button. Select
a polling interval and an interface and start polling.
Values in graph are calculated and shown as either bits or bytes per second
or utilization in percent. Just select the appropriate graph.
Error messages are shown in the statusbar at the bottom.
Other functions provided:
- Show device information
- Reset all values and graphs
- Options dialog
- Two log variations: normal log also shown in GUI and a debug log that shows
all polling information that was retrieved. Both can be written to files.
