Anticipating such scenarios, Wireshark exports a Lua interface for creating quick-and-dirty dissectors. For more information on how the protocol works and what it does see Denton Gentry’s 3-part VxLAN article or go straight to the VxLAN IETF Draftīeing a new protocol, Wireshark doesn’t yet have a built-in dissector for the VxLAN protocol. To stay on topic, we will not concern ourselves about the protocol details but only about the protocol frame format. To solve this problem VMware and Cisco have introduced a new protocol - VxLAN. Since the original post, Wireshark has introduced a built-in VxLAN dissector - but this post is still instructive for how to create a Lua dissectorĪs virtualization and cloud computing platforms are getting more and more deployed, the L2 network that the VMs are deployed in is exploding in size and VM migration from one host to another becoming problematic.
