Table 12 Port Setup

LABEL	DESCRIPTION
Port	This is the port index number.
Active	Select this check box to enable a port. The factory default for all ports is enabled. A
	port must be enabled for data transmission to occur.
Name	Enter a descriptive name that identifies this port.
Type	This field displays 10/100M for an Ethernet connection and 10/100/1000M for the
	Gigabit Ethernet/mini-GBIC ports and 100M for a 100 base-FX fiber-optic port.
Speed/Duplex	Select the speed and the duplex mode of the Ethernet connection on this port.
	For Ethernet ports, select Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half
	Duplex or 100M/Full Duplex.
	For the Gigabit Ethernet/mini-GBIC port, select Auto, 10M/Half Duplex, 10M/Full
	Duplex, 100M/Half Duplex, 100M/Full Duplex or 1000M/Full Duplex.
	For the mini-GBIC port on the ES-2108-LC, select Auto or 1000M/Full Duplex.
	The port speed and the duplex mode are fixed (100M/Full Duplex) for the 100 Base-
	FX fiber optic port on the ES-2108-LC.
	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.
