Bridging

determine the speed of the port and whether it uses full duplex or standard mode bridging.

The following information about the selected Fast Ethernet port is displayed:

Port Type

Displays the type of Fast Ethernet port for example, FE-100TX or FE-100FX.

Link State

Displays the connection status of the selected port: Link or No Link.

Current Operational Mode

Displays the mode that the port is operating in at the present time. Possible operational modes include 10Base-T, 10Base-T Full Duplex, 100Base-TX, 100Base-TX Full Duplex, 100Base-FX or 100Base-FX Full Duplex.

If no current operational mode is returned, it indicates the port is operating under auto-negotiation.

Desired Operational Mode

Displays the operational mode that you want to conÞgure for this port. The following operational modes are available for each port:

FE-100TXAuto-Negotiation, 10Base-T, 10Base-T Full Duplex, 100Base-TX, and 100Base-TX Full Duplex.

FE-100FX100Base-FX and 100Base-FX Full Duplex

See Setting the Operational Mode for the FE-100TX,page 2-76,and Setting the Operational Mode for the FE-100FX,page 2-77, for details.

Advertised Abilities

This Þeld works in conjunction with auto-negotiation on FE-100TX ports. During auto-negotiation, the local hardware will advertise all selected modes in descending bandwidth order: 100Base-TX Full Duplex, 100Base-TX, 10Base-T Full Duplex, and 10Base-T.

Of the selected abilities, the highest mode available on the port on the other side of the connection will automatically be used. The Advertised Abilities will only be used when auto-negotiation is enabled.

Remote Capabilities

This Þeld displays the advertised abilities of the remote hardware at the other end of the link from the FE-100TX port. Again, possible advertised abilities by the remote partner include 10Base-T, 10Base-T Full Duplex, 100Base-TX, or 100Base-TX Full Duplex.

If auto-negotiation is not enabled or supported at either the local or remote interface, or if there is no active link, all entries in this Þeld will be grayed out.
