(2) Auto-negotiation
Two connected devices use auto-negotiation to determine the connection conditions
(transmission speed, duplex mode (full or half), and whether to use flow control).
Reference note: For details on the connection specifications for the Switch, see Table
13-5 Connection specifications for transmission speed and duplex mode (full or half).
(3) Flow control
The flow control functionality sends a pause packet to the remote device to instruct it to
temporarily stop sending frames so that received frames are not discarded when the
reception buffer on the switch is full. Conversely, when the switch receives a pause packet,
it regulates sending to the remote device. Note that flow control is available only in
full-duplex mode.
The Switch monitors the usage of the reception buffer, and sends a pause packet to the
