This is a packet tracing tool much like snoop or tcpdump. Its superpower is

that it's P4 programmable.

## OS Support

- Illumos

## Core Capabilities

- Filter packets based on

    - IP addresses

    - IP protocol

    - L4 ports

    - Application layer protocol

    - VLAN VID

    - IP version

    - ARP

    - All the above for Geneve encapsulated packets.

- Show packet contents in nicely formatted hex.

- Render packet traces from raw data files in hex format.
