Selecting 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.
Duplex
Port duplex capabilities:
Auto:
Auto duplex with all capabilities.
Half:
Auto speed with 10/100M ability only.
Full:
Auto speed with 10/100/1000M ability only.
Flow Control
A concentration of traffic on a port decreases port bandwidth and
overflows buffer memory causing packet discards and frame losses. Flow
Control
is used to regulate transmission of signals to match the bandwidth
of the receiving port. 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.

Flow Control
Config
The Config column displays if Flow Control has been configured to be
turned On or Off for the port.
Flow Control
Status
The column displays the port’s current Flow Control status.
3.3.2 Port Mirroring
The Mirror function copies all the packets that are transmitted by the source port to the
destination port. It allows administrators to analyze and monitor the traffic of the monitored ports.
