Bridging

From this window you can manually set the operational mode of the port, determining the speed of the port (10 Mbps or 100 Mbps), and whether it uses full duplex or standard mode bridging.

You can also set a 100Base-TX port to auto-negotiation so that the appropriate operational mode can be determined automatically (using the Advertised Abilities of the local interface that you determine, and the Remote Capabilities of the Remote Link). The mode you set will determine the speed of the port and whether it uses full duplex or standard mode bridging.

To access the Fast Ethernet ConÞguration window from the Bridge Status

window:

1.Click on the desired Port button () to display the Port menu.

2.Click on Conﬁguration. The Fast Ethernet Conﬁguration Port X window (where X represents the port number of the selected interface), Figure 2-24,will appear.

To access the Fast Ethernet ConÞguration window from the Chassis View window:

1.Click on the appropriate port index to access the Port menu.

2.Click on Conﬁguration. The Fast Ethernet Conﬁguration Port X window (where X represents the port number of the selected interface), Figure 2-24,will appear.
