Abstract
Some embodiments provide a method, executable by a network device, that receives a packet from a network at a first port of the network device. The method further sends the packet to a second port of the network device. The second port includes an interface and a loopback function implemented at an egress of the interface. The loopback function is configured to transmit the packet back to the network device through the interface. The interface is configured to truncate the packet upon receiving the packet from the loopback function. Upon receiving the truncated packet from the interface of the second port, the method also forwards the truncated packet to a device through a third port of the network device that is coupled to the device.
