4–4 MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
OPERATION CHAPTER 4: OPERATION
Note In half-duplex mode, the ML2400 implements a back-pressure algorithm on 10/100 Mb
ports for flow control. That is, the switch prevents frames from entering the device by
forcing a collision indication on the half-duplex ports that are receiving. This temporary
“collision” delay allows the available buffer space to improve as the switch catches up with
the traffic flow.
