The SmartSwitch 2000 Chassis View

100Base-FX ports do not support auto negotiation for bandwidth or flow control capability, so you must choose between 100Base-FX Half Duplex and 100Base-FX Full Duplex mode, and set the flow control option. However, you must still be sure that both link partners are set to the same operational mode, or the link will be unstable.

For 1000Base-SX/LX/CX ports the speed and duplex modes are always configured at 1000MB Full Duplex. However, you can select Auto Negotiate mode, which allows the port to negotiate with its link partner to find the highest mutually available bandwidth and flow control. If you select Auto Negotiate mode, you must also choose which of the port’s bandwidth and flow control capabilities you wish to advertise to the link partner (refer to Auto Negotiation Technologies, page 2-38).

To set your desired operational mode:

1.Click on the Speed, Duplex, or Flow Control list box to display the menu of available options; click to select the operational mode you wish to set.

NOTE

If the port you are configuring does not support Flow Control, the Current Mode field will display “not supported” and the Desired Mode list box will be disabled.

2. Click on the Apply button to save your changes.

Auto Negotiation Technologies

For ports which have been configured to operate in Auto Negotiate mode, this list box allows you to select which of the operational modes available to the port will be advertised to the negotiating link partner.

During Auto Negotiation, each of the link partners will advertise all selected modes. Of the selected modes, the highest mode mutually available will automatically be used. If there is no mode mutually advertised, no link will be achieved.

If you select Auto-Negotiation at both ends of a link, be sure at least one

TIP mutually-advertised operational mode is available.

If you have manually configured specific operational modes for your 100Base-TX port or if you are configuring a 100Base-FX port, the Auto Negotiation Technologies list box does not apply.
