Chapter 39 Port Setup
XGS2220 Series User’s Guide

The following table describes the labels in this screen.
Table 136 PORT > Port Setup > Port Setup
LABEL DESCRIPTION
SLOT This field appears only in Stacking mode. Click the drop-down list to choose the slot number of
the Switch in a stack.
Port This is the port index number. In Stacking mode, the first number represents the slot ID and the
second one is the port number. Please note that the default stacking ports (the last four ports of
your Switch) cannot be configured. They are reserved for stacking only.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
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 Type a descriptive name that identifies this port. You can enter up to 128 printable ASCII
characters except [ ? ], [ | ], [ ' ] or [ " ].
Note: Due to space limitations, the port name may be truncated in some Web
Configurator screens.
Speed/Duplex Select the speed and the duplex mode of the Ethernet connection on this port.
For an Ethernet port, the choices are Auto, 10-an (10M/auto-negotiation), 10M/Full Duplex, 100-
an (100M/auto-negotiation), 100M/Full Duplex, 1G/Full Duplex, 2.5G/Full Duplex, 5G/Full
Duplex, and 10G/Full Duplex (Gigabit connections only).
For an SFP+ interface, the choices are Auto, Auto-1G, 1G/Full Duplex, and 10G/Full Duplex
(Gigabit connections only).
Selecting Auto-1G or 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.
