What is sampling rate in sFlow?
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 sampling rate in NetFlow?
The methodology that the Sampled NetFlow feature uses is deterministic sampling, which selects every nth packet for NetFlow processing on a per-interface basis. For example, if you set the sampling rate to 1 out of 100 packets, then Sampled NetFlow samples the 1st, 101st, 201st, 301st, and so on packets.
What is Juniper J-Flow?
What is J-Flow? J-Flow is data flow sampling technology developed by Juniper Networks. J-Flow is configured by default in all Juniper routers and switches. It works by monitoring each packet that flows inside a network. It allows packets in the input stream to be sampled when enabled on an interface.
What is Ipfix Juniper?
IPFIX format is a J-Flow Version9 format used for exporting IP Flow packets out of sampling and monitoring functionality of a given system. IPFIX is also known as version 10 format of export IP Flow sampling information. Use of IPFIX allows you to define a flow record template suitable for IPv4 traffic or IPv6 traffic.
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.
What is IPFIX data?
IPFIX, which stands for IP Flow Information Export, was created as a more universal solution to collecting and analyzing vital network data. And while IPFIX works with Cisco, it can also include a much wider range of vendor products and devices.
What ports does NetFlow use?
The standard or most common UDP port used by NetFlow is UDP port 2055, but other ports, such as 9555, 9995, 9025, and 9026, can also be used. UDP port 4739 is the default port used by IPFIX.
What is the difference between NetFlow and sFlow?
The most notable difference of SFlow vs NetFlow is that SFlow is network layer independent and has the ability to sample everything and to access traffic from OSI layer 2-7, while NetFlow is restricted to IP traffic only.
Is sFlow NetFlow?
The most notable difference of SFlow vs NetFlow is that SFlow is network layer independent and has the ability to sample everything and to access traffic from OSI layer 2-7, while NetFlow is restricted to IP traffic only. Does not capture any packets.
