If you define this setting on probe, group, or device level, these settings can be inherited to all sensors underneath. It's a very un-salesy, un-annoying newsletter and you can unsubscribe at any time. Testing NetFlow export configurations. interface vlan xxxx ip flow monitor PRTG-MONITOR input!ip flow monitor PRTG-MONITOR output! Use it with care. Note: In order for the sensor to work, NetFlow export of the respective version must be enabled on the device. If defined on probe, group, or device level, these settings can be inherited to all sensors underneath. A few seconds later, all dependent objects are paused. Enter an integer value. This can avoid false alarms if the monitored device only has temporary issues. : Users in this user group cannot see or edit the sensor. Make sure that the sensor matches the NetFlow version that your device exports. Thurn-und-Taxis-Str. You can choose from: To test your dependencies, select Simulate Error Status from the context menu of an object that other objects depend on. It must match the UDP port number that you configured in the NetFlow export options of your hardware router device. : Traffic from chat and instant messaging. You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. Several filter options are available to divide traffic into different channels. PRTG Manual: NetFlow v9 (Custom) Sensor. IP protocol 5. For these type of switches, where you're missing the flow command, verify first of all which type of "sdm template" (Switch Database Management) you are using by entering this command: If it shows that the "default" template is in use, you would need to update the firmware of the switch to a "lanbase-default" IOS, Follow my other article about how to upgrade the IOS in your switch: http://www.nazaudy.com/index.php/12-technology/cisco/35-upgrade-ios-in-cisco-switches-c2960s , and see if your unit support IOS version 15.0(2)EX5 so that you have the "flow" command available and are clear to proceed, One more thing, as you know well with Cisco, most of the cool features are bound to....yeap... licensing. yay! : Set up a one-time maintenance window and pause monitoring. :) You can see on the graph below how a single IP address is using all of the bandwidth of the switch: Here is the same graph, after the bandwidth process for that single IP address was stopped, Follow my other article "Use rConfig to manage your Cisco switches and Cisco tips" for more ideas and tips about Cisco switches: https://www.nazaudy.com/index.php/12-technology/cisco/57-user-rconfig-to-manage-your-cisco-switches-and-cisco-tips, Cisco IOS Flexible NetFlow; https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fnetflow/command/fnf-cr-book/, Cannot use a switchport interface as source; https://supportforums.cisco.com/t5/, Cisco Catalyst 3560-CX and 2960-CX Series Switches FAQ; https://www.cisco.com/c/en/us/products/, Configuring NetFlow Top Talkers; https://www.cisco.com/c/en/us/td/docs/ios-xml/, What is the Active Flow Timeout in Flow sensors? For details, see the Knowledge Base: field are considered. Several filter options are available to divide traffic into different channels. PRTG Manual: NetFlow v9 Sensor. NetFlow Tester simply dumps the data of all NetFlow packets that a computer receives from a Cisco router – useful when debugging bandwidth monitoring configurations based on the NetFlow protocol. Use the date time picker to enter the end date and time of the one-time maintenance window. Set sensor to warning for 5 intervals, then set to down. Shows Tags that this sensor inherits from its parent device, group, and probe.This setting is shown for your information only and cannot be changed here. Just remember that SNMP v1 does not support 64-bit, therefore please ensure that you're using either SNMP v2 or v3 to monitor your Cisco devices, If you happens to have a 32-bit sensor, just delete it and add it again; it should add as a 64-bit sensor instead. Set sensor to warning for 4 intervals, then set to down. Cisco switch 4510 does not support Netflow output option 2. To do that, edit the group in PRTG where (I suppose, and I hope so!) The sensor neither shows up in lists nor in the device tree. 1 Welcome to PRTG Network Monitor. For more information about sensor settings, see the following sections: Since 1997, our mission has been to empower technical teams to manage their infrastructure, ensuring maximum productivity. A net flow, or flow, consists of packets that share these attributes: 1. Enter an integer value. For the second part of this article, we will cover the PRTG configuration, as follows: Set Mbits units for your PRTG Ensure the channels you're monitoring are 64-bit Add the NetFlow V9 sensor Add Source and Destination IP Toplist Set Primary Toplist Create a NetFlow V9 PRTG map For more information, see the Knowledge Base: Enter one or more tags. PRTG Manual: NetFlow v9 Sensor. This document provides an example to configure NetFlow on the Catalyst 6500/6000 Switch that runs Native IOS or Hybrid OS.

This setting is only visible if you enable Select a sensor above. After the master sensor for this dependency returns to the. large FTP transfer). In this case, define delays in the parent device settings or in its parent group settings. Testing NetFlow export configurations. status only after the sixth request fails. VLAN values represent a VLAN identifier (any number). The maximum timeout is. : Traffic from various other protocols via UDP and TCP. You can define a time span for a the pause below. The principle of this configuration can be organised in two blocks, the first one deals with your Cisco switches and the second one with the PRTG console. For each type of sensor channel, define the unit in which data is displayed. The sensor can show the following traffic types in kbit per second: Which channels the sensor actually shows might depend on the monitored device and the sensor setup. For previous scanning intervals with failed requests, the sensor shows the. From this subset, you can explicitly exclude traffic, using the same syntax. status. : Do not store the stream and packet data. Verify Netflow v9 configuration: Once the Netflow is configured, then the Netflow packet is sent to a designated collector or server. Layer 3 header information 5. This setting is only visible if you enable Select a sensor above. Thinking beyond IT networks, Paessler is actively developing solutions to support digital transformation strategies and the Internet of Things. For some sensors, you can explicitly define the monitoring target in the sensor settings. See the device settings for details. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets. The below commands will ensure that the SNMP traffic generated by your Cisco switch is reachable only by your SNMP server, At this stage, you can execute #show logging in your Cisco switch, and hopefully you'll see some NetFlow traffic going to your PRTG server. The following filter rules apply to all xFlow (NetFlow, jFlow, sFlow, IPFIX) and Packet Sniffer sensors. They cannot edit its access rights settings. After the configuration is complete, NetFlow data will be exported, and you will start seeing results in the NetFlow Analyzer UI. Confirm each tag with the Spacebar key, a comma, or the Enter key. above. What security features does PRTG include? To configure NetFlow from the WatchGuard web UI: Select System > NetFlow. Mask values represent subnet masks in the form of a single number (number of contiguous bits). Enter a number that matches the sampling rate in your exporter device. This setting is not available if you set this sensor to Use parent or to be the Master sensor for parent. None of the interval options apply. Select a unit from the list. This setting is only visible when sampling mode is On above. PRTG looks very minimalistic and simple, but at the second glance it is very powerful and easy-to-use: status immediately after the first request fails. For each type of channel, select the unit in which PRTG displays the data. : Store all stream and packet data. Enter an integer value. Tags are not case-sensitive. In the first section we'll do the following in the Cisco switches: For the second part of this article, we will cover the PRTG configuration, as follows: I have tested these settings with Cisco C2960X, C3850 and C9300, in devices with the newer IOS 15.0(2a) EX5 and 03.07.04E, and the configuration works really well. 14 Choose from: You can create schedules, edit schedules, or pause monitoring for a specific time span. None of the interval options apply. Make sure that the sensor matches the NetFlow version that your device exports. You can check all dependencies under Devices | Dependencies in the main menu bar. Enter the User Datagram Protocol (UDP) port number on which the flow packets are received. For previous scanning intervals with failed requests, the sensor shows the Warning status. Monitoring is always active. Select the number of scanning intervals that the sensor has time to reach and to check a device again if a sensor query fails. Enter a meaningful name to identify the sensor. : Count all traffic of this group and further divide it into different channels. You can use schedules to monitor during a certain time span (days or hours) every week. This ignores the start and stop information of a flow as provided by the device and accounts all data to the current point in time. This tool which collects the Netflow packet make you to understand and helps to manage the bandwidth. Extensive use of this option can cause load problems on the probe system. In older IOS switches (like the C2960S) you will get the error "(%Unrecognized command)" when issuing the command (config)#flow? If you set this value too low, flow information might be lost. It only shows the setting fields that are required for creating the sensor. If you define error limits for a sensor's channels, the sensor immediately shows the. for security reasons. Do the same thing for "Destination IP", so that at the end you end up with the configuration below, where you can see separate entities for both Source and Destination IP: Visit your NetFlow V9 sensor > Settings and set the Primary Toplist to be your "Source IP", this is so that on the maps we can see the IP address from which the traffic is coming from, singling out any possibly misuse of the bandwidth. •CISCO NetFlow •Juniper ... •PRTG auto discovery will attempt to discover your network and create a sensor for each probe it discovers •Wait till auto-discovery finishes. You can only set it up on a local probe or a remote probe but not on a cluster probe. For details, see the Knowledge Base: How can I change the default groups and channels for xFlow and Packet Sniffer sensors? Set sensor to warning for 3 intervals, then set to down. : Do not account traffic of this group in its own channel. You should change them centrally in the root group settings if necessary. They cannot edit any settings. This setting determines the position of the sensor in lists. NetFlow Analyzer PRTG lets you check and monitor your bandwidth and determine, for example, the amount of network traffic caused by IP addresses, protocols, or programs.In order to carry out such an analysis, you'll configure your routers such that flow packets are sent to a computer with a PRTG probe. For more information, see section Schedules. If all goes well, you will end up with this kind of graph, just change the "Basement" string on my example for the location of your choice; very well done! above. By default Cisco Routers send a default v9 template, I am looking at adding more v9 masures into the template for seeing more network statistics, any help is appreciated. The corresponding settings from the parent objects are always active. For PRTG to better monitor Cisco switches, it is advisable to enable NetFlow in the devices, so you not only monitor the traffic but also the "source" and "destination" IP addresses from which the traffic is generated, giving you a better insight of what is happening in your network, and whom or what is utilising the bandwidth. Available for NetFlow v5, v9, and IPFIX. In the example I use a cache timeout of 60 seconds, meaning that after this time the collected data in the switch cache will be sent to the PRTG exported; the longer the cache the more load you will incur on your switches, Type "exit" one more time, and then paste the code below, resulting in a Sampler monitoring 1 packet out of a window of 32 bytes. Layer … All other options can apply. Enter an IP address to only receive data from a specific device or leave the field empty to receive data from any device on the specified port. We will send you our newsletter called “What's Up Tech World?” with fresh IT, monitoring and IoT content. Ensure the channels you´re monitoring are 64-bit, and use SNMP v2 or v3, https://www.nazaudy.com/index.php/12-technology/cisco/57-user-rconfig-to-manage-your-cisco-switches-and-cisco-tips, https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fnetflow/command/fnf-cr-book/, https://www.cisco.com/c/en/us/td/docs/ios-xml/, Enable NetFlow V9 in Cisco Switches with PRTG, PRTG System Health sensor reported as down in Cisco switches, Use rConfig to manage your Cisco switches and Cisco useful tips, Google Chrome vs iMac - server responded with 0 code, Linux popular distributions common problems and solutions, Linux Professional Institute Certification (LPIC-1) Study Guide, Linux Professional Institute Certification (LPIC-2) Study Guide, SuSe 10 running Oracle 11g - migration project, var folder is full on FreeNAS Linux - PRTG Reporting, White Hacking - Certified Ethical Hacker (CEH) vs Kali Linux Certified Professional (KLCP), Literatura, escritos de Manuel Muñoz Soria, A certificate could not be found that can be used with this Extensible Authentication Protocol, How to audit user logon sessions in Active Directory using Event ID, How to enable Remote Desktop on Windows Server, Lab Setup for Failover Clustering (exam 70-643), Microsoft Certified IT Professional (MCITP) - setup lab, Restore Windows Server Active Directory from bare metal, Set zone aging / scavenging on a DNS server, Setup and Configure a Public Key Infrastructure PKI, Como guardar los mensajes de Facebook a PDF, Why Brexit is a catastrophe for the United Kingdom, Install Squid, webmin and sent data to Splunk with CentOS 7, Configure PowerChute Personal Edition to send e-mails, ITIL 4 Foundation Certification essentials, Microsoft Outlook - An encrypted connection to your mail server is not available, Server 2012 R2 WDS (Windows Deployment Services) error 0xc00000001 when booting from PXE, This document has been signed and cannot be edited, Change IP addresses in Linux from DHCP to Static, DevOps tools to manage your infrastructure, ESXi trunk to Cisco C2960 switch - How to load balance traffic, Install onCommand Unified Manager 9.5 P1 for NetApp, NetApp simulator 9.2 - Installation and Configuration, NetApp simulator 9.6 - Installation and Configuration, Splunk Enterprise and VMware & NetApp monitoring, Upgrade VMware vSphere 5.0 to VMware vSphere 5.5, HMTL Before: Basement. You can check all dependencies under. Once you have added your Cisco switch device in PRTG, right-click on it and choose "add sensor",  then add the NetFlow V9 sensor, and configure it with these settings: And yes, set the Sampling Mode to "on", and ensure the Active Flow Timeout is set to 1 minute, and the "Sampling Rate" set to 32, just as we configured our sampler PRTG-SAMPLER in the Cisco switch earlier. Store stream data only for the 'Other' channel, : Only store stream and packet data that is not otherwise filtered and is therefore accounted to the default. The NetFlow V9 sensor receives traffic data from a NetFlow V9 compatible device and shows the traffic by type. This ignores the start and stop information of a flow as provided by the device and accounts all data to the current point in time. Schedules, Dependencies, and Maintenance Window. We recommend that you set specific, well-chosen filters for the data you really want to analyze. Besides network monitoring and accounting, system administrators can identify various problems that may occur in the network. We build lasting partnerships and integrative, holistic solutions to achieve this. These previous steps have been in our VMware environment, now it's time to configure NetFlow in our PRTG server. It is not possible to immediately set a WMI sensor to the Down status, so the first option does not apply to these sensors. NetFlow configuration settings are found under the Reporting header, with the following options: NetFlow traffic reporting. If a channel uses lookup values, the sensor immediately shows the Down status. If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. The table contains all user groups in your setup. If the timeout is reached and no new data was received during this time, the sensor changes to an Unknown status. Enabling this setting can create huge data files. You can change (nearly) all settings in the sensor's Settings tab later. You can use dependencies to pause monitoring for an object depending on the status of a different object. The NetFlow v9 sensor receives traffic data from a NetFlow v9-compatible device and shows the traffic by type. By default, PRTG shows this name in the. ) Flexible NetFlow configuration involves creating a Flow Monitor, Flow Exporter and a Flow Record. Devices compatible with NetFlow produce data that can be exported to a NetFlow collector/software agent. It can be necessary to monitor the traffic that flows through the Catalyst 6500/6000 when it acts as a core device in the network. above. For more details, see the Knowledge Base: What is the Active Flow Timeout in Flow sensors? Select the IP addresses on which PRTG listens to NetFlow packets. Click and use the object selector to select a sensor on which the current object will depend. However, there is an advanced procedure to do so. Additionally, the sensor is paused if the parent group is paused by another dependency. The highest priority is at the top of a list. The available options depend on what channels are available for this sensor. Select the IP addresses on which PRTG listens to NetFlow packets. None of the interval options apply. You see a table with user groups and group access rights. Flexible Netflow (FnF) Configuration for PRTG Friday, February 06, 2015 Cisco. A few seconds later, all dependent objects are paused. 1 minute is Choose from: Sensors that monitor via Windows Management Instrumentation (WMI) always wait at least one scanning interval before they show the Down status. If you add the clone to the, probe, PRTG keeps the selected IP addresses on which it listens for xFlow (NetFlow, jFlow, sFlow, IPFIX) packets. Use the date time picker to enter the start date and time of the one-time maintenance window. SNMP support allows you as the PRTG administrator to capture … If you define error limits for a sensor's channels, the sensor immediately shows the Down status. Therefore, you do not see all setting fields in this dialog. If the second request also fails, the sensor shows the, Set sensor to warning for 2 intervals, then set to down. Use the date time picker to enter the end date and time of the one-time maintenance window. We recommend that you only use this setting for a short time. Interface 2. Set sensor to warning for 1 interval, then set to down (recommended), status after the first request fails. As Traffic-Flow is compatible with Cisco NetFlow, it can be used … For cloning this sensor, the following rules apply. After the master sensor for this dependency returns to the Up status, PRTG additionally delays the monitoring of the dependent objects by the time span you define. Tags are automatically inherited.
