Adaptive switching

Adaptive switching mode is a user-defined facility to maximize the efficiency of the switch. Adaptive switching starts in the default switch forwarding mode you have selected (cut-through if you selected adaptive mode as the default switching mode). Depending on the number of runts and CRC errors at that port, the mode changes to the "best" of the other two switching modes. As the numbers of runts and CRC errors change, so does the forwarding mode.

This is best illustrated by the table below:

Switching mode:	Defects:	Then, adaptive mode changes the switching mode to:
Cut-through	High numbers of CRC errors	Store-and-forward
Cut-through	High numbers of runts	Fragment-free
Fragment-free	High numbers of CRC errors	Store-and-forward
Fragment-free	Low numbers of runts	Cut-through
Store-and-forward	Low numbers of CRC errors	Fragment-free
Store-and-forward	Low numbers of CRC errors and runts	Cut-through
