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 1000BASE-T cable for connection between the Switch port
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 full-duplex use 802.3x flow control, half-duplex ports use
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.
