6-5 Port Description

The AT-9724TS supports a port description feature where the user may name various ports on the Switch.To assign names to various ports, click the Port
Description on the Configuration menu:
Use the From and To pull down menu to choose a port or range of ports to describe and Unit to choose the Switch in the switch stack, and then enter a
description of the port(s). Click Apply to set the descriptions in the Port Description Table.
Allied Telesyn AT-9724TS High-Density Layer 3 Stackable Gigabit Ethernet Switch
Description
Toggle the State <Enabled> field to either enable or disable a given port or group of ports.
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
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
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.
