Speed/Duplex
<Auto>
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
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 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
.
Learning
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, if to enhance security or efficiency. See the section on
Forwarding/Filtering
for information on entering MAC addresses into the
forwarding table. The default setting is
Disabled
.
