Table 6-5 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 10/100/1000M for this connection.
Speed/Duplex Select the speed and the duplex mode of the connection on this port.
For mini GBIC slots, select Auto or 1000M/Full Duplex .
For mini Gigabit Ethernet or 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 Gigabit 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 Gigabit 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 Gigabit 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.
