Allied Telesis AT-9724TS Port Description, Parameter Description State, Speed/Duplex, Learning

Parameter	Description
State	Toggle the State <Enabled> field to either enable or disable a given port or group of ports.
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 and 100Mbps devices, in full- or half-duplex.The Auto setting allows the
	port to automatically determine the fastest settings the device the port is connected to can handle, and then to
	use those settings.The other options are Auto, 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 1000T 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
Flow Control	result in a link down status for both ports.
	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
Learning	of the two.The default is Disabled.
	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 reasons of security or efficiency. See the
	section on Forwarding/Filtering for information on entering MAC addresses into the forwarding table.
	The default setting is Disabled.
