Port Description Settings
The Switch supports a port description feature where the user may name various ports on the Switch.
Speed/Duplex Toggle the Speed/Duplex field to either select the speed and duplex/half-
duplex state of the port. Auto denotes auto-negotiation between 10/100/1000
Mbps devices, in full-duplex or half-duplex. The Auto setting allows the port to
automatically determine the fastest settings between the connected devices
and to use those settings. The other options are Auto, 10M Half, 10M Full,
100M Half and 100M Full, 1000M Full_Master, 1000M Full_Slave and 1000M
Full. 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 only support full duplex
connections and take on certain characteristics that are different from the
other choices listed.
The 1000M Full_Master and 1000M Full_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_Master) 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_Slave) uses loop timing, where
the timing comes from a data stream received from the master. If one
connection is set for 1000M Full_Master, the other side of the connection must
be set for 1000M Full_Slave. 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.
Address Learning When Enabled, destination and source MAC addresses are automatically
listed in the forwarding table. The default setting is Enabled.
Medium Type This applies only to the Combo ports. The command is available for the user
to enable or disable the port with the specified medium type. When one
medium type specified is enabled, the other medium type is disabled implicitly.
That is, each of the two types of the transport medium shall be enabled
exclusively. Both of the medium types of a specified port can be disabled at
the same time. The Copper port is selected (enabled) by default.
MDIX This can be specified as Auto, Normal, or Cross. In Normal state, the port is in
MDIX mode and can be connected to a PC NIC using a straight cable. If it is
in Cross state, the port is in MDI mode, and can be connected to a port (in
MDIX mode) on another switch through a straight cable.
