What is nProbe ntop?

nProbe includes both a NetFlow v5/v9/IPFIX probe and collector that can be used to play with NetFlow flows. This means nProbe™ can be used: To collect and export NetFlow flows generated by border gateways/switches/routers or any other device that can export in NetFlow v5/v9.

What is NetFlow JFlow sFlow?

Jflow and Netflow are essentially identical. JFlow and CFlow are the same as CISCO Netflow v5. Only NetFlow v9 supports IPv6. Unlike NetFlow, the sFlow® protocol samples every N-th packet from the traffic stream, where N can be one-in-512, one-in-1024, etcetera.

Does Cisco support sFlow?

Beginning with Cisco NX-OS Release 7.0(3)I5(1), sFlow is supported on Cisco Nexus 9200 and 9300-EX Series switches. Beginning with Cisco NX-OS Release 7.0(3)I5(2), sFlow is supported on Cisco 9500 Series switches with 9700-EX line cards.

What is sFlow protocol?

sFlow, short for “sampled flow”, is an industry standard for packet export at Layer 2 of the OSI model. sFlow was originally developed by InMon Corp. It provides a means for exporting truncated packets, together with interface counters for the purpose of network monitoring.

What is sFlow sampling rate?

The sampling rate is the average ratio of the number of packets incoming on an sFlow-enabled port to the number of flow samples taken from those packets. sFlow sampling can affect performance in some configurations. Note that on the RUCKUS ICX devices, the configured sampling rate and the actual rate are the same.

What is sFlow agent?

The sFlow Agent is a software process that runs as part of the network management software within a device (see Figure 2). It combines interface counters and flow samples into sFlow datagrams that are sent across the network to an sFlow Collector.

What is sFlow agent IP?

The sFlow Agent IP address identifies the Device/Chassis that the packet is coming from. It can be configured to take the IP of either an ethernet or a loopback or a ve interface; but cannot be configured to take the IP address of the Management interface.

Is Cisco NetFlow free?

The NetFlow Traffic Analyzer can communicate with network devices using the NetFlow, sFlow, J-Flow, NetStream, and IPFIX protocols. Although this tool is not free forever, however, you can start with a 30-day free trial.

Is sFlow UDP or TCP?

By default, sFlow uses UDP port 6343 (this can be changed if required – see Section 13.2.

What is sFlow polling?

The polling interval defines how often sFlow byte and packet counter data for a port is sent to the sFlow collectors. If multiple ports are enabled for sFlow, the device staggers transmission of the counter data to smooth performance.
