| then to use those settings. The other options are 10M/Half, 10M/Full, 100M/Half |
| and 100M/Full, 1000M/Full_M and 1000M/Full_S. There is no automatic |
| adjustment of port settings with any option other than Auto. |
| The Switch allows the user to configure two types of gigabit connections; |
| 1000M/Full_M and 1000M/Full_S. Gigabit connections are only supported in full |
| duplex connections and take on certain characteristics that are different from the |
| other choices listed. |
| The 1000M/Full_M (master) and 1000M/Full_S (slave) parameters refer to |
| connections running a |
| and other device capable of a gigabit connection. The master setting |
| (1000M/Full_M) will allow the port to advertise capabilities related to duplex, speed |
| and physical layer type. The master setting will also determine the master and |
| slave relationship between the two connected physical layers. This relationship is |
| necessary for establishing the timing control between the two physical layers. The |
| timing control is set on a master physical layer by a local source. The slave setting |
| (1000M/Full_S) uses loop timing, where the timing comes form a data stream |
| received from the master. If one connection is set for 1000M/Full_M, the other |
| side of the connection must be set for 1000M/Full_S. Any other configuration will |
| result in a link down status for both ports. |

Flow Control | Displays the flow control scheme used for the various port configurations. Ports |
| configured for |
| backpressure flow control, and Auto ports use an automatic selection of the two. |
| The default is Disabled. |
|
|
Learning | Enable or disable MAC address learning for the selected ports. When Enabled, |
| destination and source MAC addresses are automatically listed in the forwarding |
| table. When learning is Disabled, MAC addresses must be manually entered into |
| the forwarding table. This is sometimes done for security or efficiency reasons. |
| See the section on Forwarding for information on entering MAC addresses into the |
| forwarding table. The default setting is Disabled. |
