DGS-3700-12/DGS-3700-12G Series Layer 2 Gigabit Ethernet Switch User Manual

Parameter Description

From Port / To Port

Use the pull-down menus to select the port or range of ports to be configured.

State

Toggle this 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 100 Mbps 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, 1000M/Full_S 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_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.

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. If configuring the Combo ports this defines the type of

transport medium used. SFP ports should be set at Fiber and the Combo 1000BASE-T ports

should be set at Copper.

Port Description

The Switch supports a port description feature where the user may assign names to various ports on the Switch.

Use the From Port / To Port pull-down menu to choose a port or range of ports to describe, and then enter a

description of the port(s). Click Apply to set the descriptions in the Port Description Table.

The Medium Type applies only to the Combo ports. If configuring the Combo ports this defines the type of tranport

medium used. SFP ports should be nominated Fiber and the Combo 1000BASE-T ports should be nominated Copper.

The result will be displayed in the appropriate switch port number slot (C for copper ports and F for fiber ports).
