Table 10 Configuration > Port Configuration

LABEL	DESCRIPTION
Port	This is the port number.
Name	Enter a descriptive name that identifies this port. You can enter
	up to 64 alpha-numerical characters.

	Note: Due to space limitation, the port name may be
	truncated in some Web Configurator screens.
Admin	Use this to enable or disable administrative access through this
	port.
Speed	Select the port’s current speed (10M for 10 Mbps and 100M for
	100 Mbps). The speed for the fiber ports is fixed.
Duplex	Use this field to change the status to Half or Full duplex mode.
	The duplex status for the fiber ports is fixed.
AUTO	Use this to enable or disable 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 MES-2110 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 MES-2110 determines the connection speed
	by detecting the signal on the cable and using half duplex mode.
	When the MES-2110’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	Use this to enable or disable flow control.
	A concentration of traffic on a port decreases port bandwidth and
	overflows buffer memory causing frame discards and frame
	losses. Flow Control is used to regulate transmission of signals
	to match the bandwidth of the receiving port.
	The MES-2110 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
	frame collision) causing the sending port to temporarily stop
	sending signals and resend later.
Port	This indicates the port number
Name	This indicates the descriptive named assigned to the port.
Admin	This indicates whether administrative access is enabled or
	disabled for this port.
Speed	This indicates the speed assigned to the port (10M for 10 Mbps
	and 100M for 100 Mbps).
