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

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;
        }
    }
}
```

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

content_copy zoom_out_map
[edit interfaces]
interface-name {
    unit logical-unit-number {
        family family-name {
            filter {
                input filter-name;
            }
            address address {
                destination destination-address;
            }
        }
    }
}

Enable sampling and specify a nonzero sampling rate:

[edit forwarding-options]
sampling {
    input {
        rate number;
    }
}
