Juniper sFlow Configuration

This document outlines the configuration steps for implementing sFlow on a Juniper router.

Configuration Example​

You can perform Juniper router Flow configuration using the following sample configuration:

protocols { 
    sflow {
        polling-interval 30;
        sample-rate 500;
        collector {MOTADATA_COLLECTOR_IP} {
            udp-port 6343;
        }
        interfaces ge-0/0/0.0;
        interfaces ge-0/0/1.0;
        interfaces ge-0/0/2.0;
        interfaces ge-0/0/3.0;
        interfaces ge-0/0/11.0;
    }
}

After completing the configuration, navigate to Menu > Flow Explorer and select the Event Source(s) and the associated Interface(s) from the drop-downs to view the active flow data.
