LinuxCon North America/CloudOpen North America

In data center topologies, right cabling is a time consuming endeavor and is error-prone. PTMD is a dynamic cabling verification tool to help eliminate such errors. It takes a graphviz-DOT specified network cabling plan (something many operators already generate) and couples it with runtime information derived from LLDP to verify that the cabling matches the specification. The check is performed on every link transition on each node in the network. PTMD runs as a Linux daemon. It has been tested on switches running Linux and by the time of the talk, the code will be hosted on github. The talk is primarily targetted for system administrators. The audience will get to know: Design and implementation of PTMD, Configuration examples, Use cases such as integration with Quagga-based routing protocol suite.
