Abstract
Introduced here is a technique for using a network switch device, which may include commodity switching fabric, to route packets through an inline tool, without introducing any additional information to the packets. The introduced technique modifies standard capability of packet forwarding and learning port-to-MAC address associations to route data packets through the inline tool. The technique may include applying two override settings to the network device. A first override setting involves a forwarding rule that is based on the arrival port and the content of the packet. A second override setting involves disabling the MAC address learning mechanism for the packet received from the inline tool via the second tool port of the network device.
