Expansion Port Information
The Expansion Port Information screen displays the port status, link state, the
communication speed and duplex mode, as well as the flow control in use. To
change any of the port settings, use the Expansion Port Configuration menu. The
parameters shown in the following figure and table are for expansion ports.
Parameter Description
Admin Status Shows if the port is enabled or not.
Link Status Indicates if the port has a valid connection to an external device.
Duplex Status Displays the current duplex mode.
Flow Control Status Shows the flow control type in use. Flow control can eliminate frame loss by
“blocking” traffic from end stations connected directly to the switch. Back pressure
is used for half duplex and IEEE 802.3x for full duplex. Note that flow control
should not be used if a port is connected to a hub.
