Abstract
Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer, at least one packet interface, and an analysis assist layer. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis assist layer analyzes the packet to determine a reason code to assign to the packet. The analysis and bifurcation layer then analyzes the packet based at least in part on the reason code.
