Chapter 6: Configuration

Current Link Speed: Provide the current link speed of the port.

Configured Link Speed: Select any available link speed for the given switch port.

Auto Speed selects the highest speed that is compatible with a link partner.

Disabled disables the switch port operation.

Flow Control: When Auto Speed is selected on a port, this section indicates the flow control capability that is advertised to the link partner. When a fixed-speed setting is selected, that is what is used.

The Rx and Tx settings are determined by the result of the last Auto-Negotiation.

Check the configured column to use flow control. This setting is related to the setting for Configured Link Speed.
