Interface objects respectively corresponding to each internal interface of the network device are rendered within the object representing the network device. A network flow record for a network flow through the network device is acquired. The network flow record identifies ingress and egress interfaces of the network device for the network flow. Switching information for the network flow within the network device is determined based on the ingress and egress identifications. A transmission path of the network flow within the network device from the ingress interface is rendered within the object representing the network device. The transmission path is defined by the switching information identified by the network flow record. ## Claims ### Claim 1 A method for visualization of internal network flow within a network device, comprising: rendering, on a computer system display, a graphical user interface including an object representing a network device;
