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 (up to nine printable characters) that identifies this port.
Type This field displays 10/100/1000M for the Gigabit Ethernet/ mini-GBIC ports or 1000M
for the mini-GBIC ports.
Speed/Duplex Select the speed and the duplex mode of the connection on this port. Choices are
Auto, 10M/Half Duplex, 10M/Full Duplex, 100M/Half Duplex, 100M/Full Duplex
and 1000M/Full Duplex.
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.
