Auto Negotiation

Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the
connection speed and duplex mode that both ends support. When auto-negotiation is turned on,
a port on the Switch negotiates with the peer automatically to determine the connection speed
and duplex mode.
If the peer port does not support auto-negotiation or turns off this feature, the Switch determines
the connection speed by detecting the signal on the cable and using half-duplex mode. When the
Switch's auto-negotiation is turned off, a port uses the pre-configured speed and duplex mode
when making a connection, thus requiring you to make sure that the settings of the peer port are
the same in order to connect.
Flow Control

A concentration of traffic on a port decreases port bandwidth and overflows buffer memory
causing packet discards and frame losses.IEEE802.3x flow control is used in full duplex mode
to send a pause signal to the sending port, causing it to temporarily stop sending signals when
the receiving port memory buffers fill and resend later.
The Switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in
half duplex mode. IEEE802.3x flow control is used in full duplex mode to send a pause signal to
the sending port, causing it to temporarily stop sending signals when the receiving port memory
buffers fill. Back Pressure flow control is typically used in half duplex mode to send a "collision"
signal to the sending port (mimicking a state of packet collision) causing the sending port to
temporarily stop sending signals and resend later.
Note: 1000 Base-T does not support force mode.
Notices:
The default port Speed & Duplex is auto for all ports.
The default port Flow Control is Off for all ports.
