I've been getting ready for the CCENT exam and I just came across the content for the different types of switching. Is there a way to configure one or the other in terms of cut through vs store and forward on a 2960? Or is this something that's hard coded into the switch itself?
The first switches (made by Kalpana, who was later bought by Cisco). Kalpana was the first, and they did it with custom proprietary hardware.
The store-and-forward was much higher latency through the switch. Then Cisco came out with "Fragment Free" switching - meaning that the switch would accept the first 64 bytes, evaluate it, then forward it.
By getting at least 64 bytes, the switch could guarantee the the frame was not a runt (runt is a frame < 64bytes, the minimum permissable Ethernet frame size), and could make sure that the addresses were not corrupt.
I remember that the catalyst 1924 is set for fragment-free switching which was very old switch.
But presently the switches are operating with Store-and-forward and cut-through switching
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
