Cut-Through (ASF) Commands
The Cut-through Mode (or Alternative Store and Forward Mode, ASF) feature allows the switch to operate in a
mode such that the egress pipeline begins transmitting a packet before the ingress pipeline has completely
received the entire packet. Enabling this mode decreases latency for large packets.
Alternate Store and forward (ASF) reduces latency for larger packets. In this mode, the MMU is allowed to
forward a packet to the egress port before it has been entirely received in the Cell Buffer Pool (CBP) memory.
These switch devices provide a threshold to define how many cells must be received before the MMU is
allowed to dispatch a packet to the egress.
cut-through mode
Use this command to enable or disable cut-through mode on the switch. If you change the mode, you must
reload the switch for the mode to take effect.
no cut-through mode
This command resets the cut-through mode to the default value.
