Minimum Traffic Sampling 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 {rate number;}}
