Overview

When you configure a device to send sFlow to a collector, you simply set a source IP address (IP address of the collector), sample-rate, polling interval, UDP port, and interface to capture from. There is no opportunity to filter or choose what data gets sent from the device side. 

Steps Of Configuration

The following is an example configuration snippet to configure an MX series router to send sFlow packets.

set sflow collector 10.234.32.46 udp-port 5600

set sflow interfaces ge-0/0/0
set sflow polling interval 20
set sflow sample-rate egress 1000
set sflow interfaces ge-0/0/1 polling-interval 10 sample-rate ingress 1000

The following is an example configuration snippet to configure an EX series switch to send sFlow packets.

set sflow collector 10.234.32.46 udp-port 5600

set sflow interfaces ge-0/0/0
set sflow polling interval 20
set sflow sample-rate egress 1000

The following example shows the output from a switch already configured to send sFlow packets to a collector at IP address.

user@switch# show
    polling-interval 20;
    sample-rate egress 1000;
    collector 10.204.32.46 
    {
        udp-port 5600;
    }
    interfaces ge-0/0/0.0;

Login to the CCE server and run the below command 

sudo tcpdump -i any port 6343 and host <IP Of Device>
