Hi Suricata! I am new to Suricata, and I am trying to find the YAML Reference for `af-packet` I would have expected to find the reference here: [12.1. Suricata.yaml — Suricata 8.0.1-dev documentation](https://docs.suricata.io/en/latest/configuration/suricata-yaml.html). However, I cannot seem to find a section for `af-packet`.

We have an example in the quick start – see [2. Quickstart guide — Suricata 8.0.1-dev documentation](https://docs.suricata.io/en/latest/quickstart.html#basic-setup)
This example is for IDS mode – since you’re new to Suricata, I’m assuming that’s the mode you’ll use. In IDS mode, Suricata receives a _copy_ of packets that traverse the network. The other common mode is IPS – inline mode - where Suricata acts as a bridge between two network interfaces.

Hi @Jeff_Lucovsky , thanks for linking the sample in the quick start, where could I find all options for `af-packet` or is it just those mentioned in the quick start?

The af-packet options are in the `suricata.yaml` file – most will be commented out with a brief description, and the default value will be listed.
