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 For mini GBIC port, this field displays 1000M .
For mini GBIC/Gigabit Ethernet combo port, this field displays 10/100/1000M .
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.
For mini GBIC ports, select Auto or 1000M/Full Duplex .
For mini GBIC/Gigabit Ethernet combo ports, select Auto , 10M/Half Duplex , 10M/Full Duplex ,
100M/Half Duplex , 100M/Full Duplex or 1000M/Full Duplex.
Selecting Auto (auto-negotiation) makes one port able to negotiate with a peer 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 Ethernet 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 Ethernet port are the same in order to connect.
