Using the System Configuration Program

Viewing the

Current Port

Configuration

The Port Information screen displays the port type, status, link state, and

flow control in use, as well as the communication speed and duplex

mode. To change any of the port settings, use the configuration menu.

The parameters shown in the following figure and table are for the RJ-45

ports.

Parameter Description

Type Shows port type as:

10/100TX: 10Base-T / 100Base-TX

100FX: 100Base-FX

1000SX: 1000Base-SX

1000LX: 1000Base-LX

Operational Shows if the port is functioning or not.

Link Indicates if the port has a valid connection to an external device.

FlowControl InUse 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.

Speed and Duplex InUse Displays the current port speed, duplex mode, and if auto-

negotiation is used. Note that auto-negotiation is available only for

RJ-45 and Gigabit ports (not 100Base-FX ports.)
