The switch is fragment-free.
The exception to fragment-free switch is that it stores the first 64 bits of the frame before forwarding.
If necessary, the source MAC and port can be updated with a fragment-free buffer. The frame is discarded if it’s less than 64byte.
The frame is forwarded to Port 4 when the switch receives it.
A cut-through switch can make a forwarding decision when it gets the destination MAC address of the frame. It doesn’t need to wait for the rest of the frame to make a decision.
If the data field is shorter than 46 BYTES, it must be replaced by the PAD field. There is a reason for the minimum length to be determined.
There is a switch in the network. Multiple devices are connected. The frame is processed using the sender and receiver devices. When a switch receives a frame, it reads the source address and stores it in a table called the CAM table.
When a frame arrives at a switch interface, the switch looks for the hardware address in the table. The frame is only sent out if the destination address is in the table. The frame will not be transmitted.
The answer is that fast-forward switch begins to forward a frame after reading the destination address. Before forwarding, fragment-free reads the first 64byte. Store-and-forward has the highest latency because it reads the entire frame first.
The second method, fast switch, is a faster method by which the first packet in a flow is routed and rewritten by a route processor using software and each subsequent packet is handled by hardware. Hardware forwarding tables are used for most common traffic flows.
