xdptap - Fault Injection: Duplicating Packets
May 26, 2025
This is about the third fault type that can be injected with xdptap in bridging mode: Packet duplication. It works similar to the other two fault types: Fault injection needs to be enabled on the RX interface and the probability is controlled by setting fault.dup.probability to the desired value.

This post explains how to collect packets and record traffic with xdptap and collect.
xdptap - Fault Injection: Corrupting Packets
May 25, 2025
This post is about corrupting packets with xdptap. This is done by flipping a single bit at a random position in the packet payload data. The area where one single bit is flipped starts at byte 15 thus always leaving the destination MAC address, the source MAC address and the first Ethertype untouched.
xdptap - Fault Injection: Dropping Packets
May 25, 2025
Nobody working at network and data center operations usually likes packet loss, even just a small percentage of packet loss can have serious effects on overall quality, bandwidth and end user experience. xdptap allows to inject different networking faults when acting as a transparent bridge. This post explains how to configure packet loss generally and also selectively.
