You can use Traceflow to inspect the path of a packet as it travels from one logical port on the logical network to another logical port on the same network. Traceflow traces the transport node-level path of a packet injected at a logical port. The trace packet traverses the logical switch overlay, but is not visible to interfaces attached to the logical switch. In other words, no packet is actually delivered to the test packet’s intended recipients. You can use the port connection tool to quickly visualize and troubleshoot the connection between two VMs.
