configure forwarding switching-mode
Description
Configures the switching mode as either cut-through or store-and-forward.
Syntax Description
cut-through | Specifies that a packet can begin being transmitted prior to its being received in full. |
store-and-forward | Specifies that a packet is transmitted only after the entire packet has been received and stored in the packet memory. |
Default
Store-and-forward.
Usage Guidelines
Use this command to configure the switch to begin transmitting a packet before its entire contents have been received. This reduces the forwarding latency of the switch.
Cut-through mode cannot be achieved for packet sizes that are less than or equal to 384 bytes. On the Summit X770 and X670-G2, cut-through can be achieved for all packet sizes.
To display the switch mode settings, use the show forwarding configuration command.
