CONSOLE INTERFACE

Configuring Interface Connections

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

Field Attributes

•Type – Shows port type (page 4-7).

•Enabled – 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.

•Auto Negotiate – Enables/disables auto-negotiation.

•Speed/Duplex Config – Manually sets port speed and duplex mode.

•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. (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.)

•Group – Assigns a port to a trunk group. (Range: 1-4)

To set a trunk as a dynamic link, use the LACP menu (page 4-47).

Note: Auto-negotiation must be disabled before you can manually force a port to use the speed/duplex mode or flow control options.
