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]

   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;

   }

   }

   }
