PFE resiliency: Dynamic port swap from 40G to 100G without restarting the Packet Forwarding Engine (PFE)

You can configure different system modes to achieve varying levels of port density on switches without restarting the Packet Forwarding Engine (PFE). The switch has fixed 32 front panel network ports. Four 100G ports can either function as 32x40G or 20x40G -- 4x100G. You can combine the port configurations supported into default mode or non-oversubscribed mode. The dcpfe restart is triggered with the mode change.
