Cut-Through Mode

Cut-through mode enables a frame to be forwarded to a destination address even before the entire frame has been received. You can configure the required number of cells to be received before transmission starts.

Refer to Figure 15-1 for a comparison of Store-and-Forward and

Cut-Through modes.

Timeout Tuning	Timeout tuning is used for assigning timeout delays for both hardware
	and software. These parameters are used to avoid cells being stuck in the
	7600 Card for extended periods of time. This usually occurs when the
	frame was not assembled correctly and is too long, or the last cell of the
	frame was not received from the ATM ports. The timeout mechanism only
	applies to frames arriving from the ATM on their way to the Ethernet
	ports or the software. The mechanism gets rid of these frames by
	terminating them as erred frames.
