Configures the switching mode as either cut-through or store-and-forward.
| 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. |
Store-and-forward.
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.
To display the switch mode settings, use the show forwarding configuration command.
This command was first available in ExtremeXOS 12.3.
Cut-through forwarding mode is supported on all ports on the ExtremeSwitching X695 series switch (subject to limitation on the source and destination port speeds if the source port speed is faster than the destination).
