CONFIGURING THE SWITCH

Configuring Interface Connections

Use the Port Configuration and Trunk Configuration pages to enable/disable an interface, manually set the speed and duplex mode, set flow control, and set auto-negotiation parameters.

Fields and Attributes

Name – Allows you to label an interface. (Range: 1-64 characters)

Admin – Allows you to manually disable an interface. You can disable an interface due to abnormal behavior (e.g., excessive collisions), and then reenable it after the problem has been resolved. You may also disable an interface for security reasons.

Speed/Duplex – Allows manual selection of port speed and duplex mode (i.e., with auto-negotiation disabled.)

Flow Control – Allows automatic or manual selection of flow control.

Flow control can eliminate frame loss by “blocking” traffic from end stations or segments connected directly to the switch when its buffers fill. When enabled, back pressure is used for half-duplex operation and IEEE 802.3x for full-duplex operation.

Flow control should not be used if a port is connected to a hub. Otherwise flow control signals will be propagated throughout the segment.

Autonegotiation/Port Capabilities – Allows auto-negotiation to be enabled/disabled. Specifies the capabilities to be advertised for a port during auto-negotiation. The following capabilities are supported:

10half - Supports 10 Mbps half-duplex operation

10full - Supports 10 Mbps full-duplex operation

100half - Supports 100 Mbps half-duplex operation

100full - Supports 100 Mbps full-duplex operation

1000full - Supports 1000 Mbps full-duplex operation
