DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
The following parameters can be configured:
Parameter Description
From…. To 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 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
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 fiber port Speed/Duplex only
supports Auto and 1000M/Full.
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 from 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
.
Medium Type This applies only to the Combo ports. If configuring the Combo ports this defines the type of
transport medium being configured. SFP ports should be set at
Fiber
and the Combo
1000BASE-T ports should be set at
Copper
if no medium type is specified the device will
assume the Copper port is the one being configured.
MDIX MDIX can be set to
Auto
,
Normal
and
Cross
depending on the cable type used for the
connection.
Learning When
Enabled
, destination and source MAC addresses are automatically listed in the forwarding
table. The default setting is
Enabled
.
