Traffic Sampling and Forwarding Configuration > Minimum Traffic Sampling or Forwarding Configuration

To configure traffic sampling, you must perform at least the following tasks:

1. Create a firewall filter to apply to the logical interfaces being sampled by including the filter statement at the [edit firewall family family-name] hierarchy level. In the filter then statement, you must specify the action modifier sample and the action accept.

[edit firewall family family-name]

filter filter-name {

    term term-name {

        then {

            sample;

            accept;

        }

    }

}

2. Apply the filter to the interfaces on which you want to sample traffic:

[edit interfaces]

interface-name {

    unit logical-unit-number {

        family family-name {

            filter {

                input filter-name;

            } 

            address address {

                destination destination-address;

            }

        }

    }

}

3. Enable sampling and specify a nonzero sampling rate:

[edit forwarding-options]

sampling {

    input {

        family inet {

            rate number;

        }

    }

}
