PORT CONFIGURATION

Configuring Interface Connections

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

Field Attributes

•State – 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.

•Autonegotiation – Enables/disables auto-negotiation.

•Speed – Allows manual selection of port speed.

•Duplex – Allows manual selection of duplex mode.

•Flow Control – Allows 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. (Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.)

Note: Autonegotiation must be disabled before you can configure or force the interface to use the Speed, Duplex mode or Flow Control options.

Web – Click Administrator=>Port Controls. Modify the required interface settings, and click Apply.
