Figure 1: PTF container testbed

- *PTF docker*: A docker container that has 32 ports with pre-installed PTF tools. See https://github.com/Azure/sonic-buildimage/tree/master/dockers/docker-ptf
- *Vlan ports*: 32 vlan ports are created on top of physical port, e.g., eth0, inside the Linux host
- *Openvswitch*: Connect 32 vlan ports to the 32 docker ports inside the Linux host. Openvswitch forwards the packet to the corresponding output port based on the incoming port. No L2/L3 forwarding is enabled in the Openvswitch.
- *Fanout switch*: A physical switch which enables VLAN trunking. Et33 is a vlan trunking port and is connected to the eth0 port of the linux host. Et1-Et32 are vlan access ports and are connect to DUT.
