Transport Channel Capacity
: Select the capacity required. Capacity options are
displayed in multiple of 2 Mbps to a maximum 32 Mbps. Ensure the required
transport channel capacity is supported within the Link capacity setting.
3. Basic Port Settings :
3.1 Enabled : Click to enable or disable the required ports. A port must be enabled
to allow traffic flow. This enabling/disabling function does not affect the Port
Up and Resolved status indications.
3.2 Name : Enter the port name or other relevant port data.
3.3 Duplex - Speed : Click to view and select auto-detect or a specified
connection type and speed. The normal setting is Auto, where the auto
negotiation feature senses and sets the speed (10 or 100Base-T) and
connection for half or full duplex operation. The fixed options would be used in
instances where auto negotiation fails to provide the expected result or where a
fixed setting is preferred:
•Auto negotiation is not 100% reliable, particularly so where the connected
equipment is using an older auto-sensing mechanism.
•Links with a duplex mismatch will operate, but will generate a large number of
errors and will slow throughput.
•Generally, for auto negotiation, both interfaces should be set to auto for speed
and duplex.
• Full-duplex can only be achieved if both interfaces are either set for
auto-negotiation or are manually configured to use full duplex.
•Full duplex will not operate via a hub/repeater. These are half duplex devices.
•If auto-negotiation is enabled on only one side of the link, it will
always default
to half-duplex, regardless of what the other side of the link is forced to.
•If one side of a link is forced to full duplex and the other is set to
auto-negotiation, a duplex mismatch will occur.
•You can force a new auto-negotiation by simply unplugging a host cable for 10
seconds.
•Most 10 Mb interfaces can run only in 10 Mb half-duplex mode.
•Most 10/100 Mb interfaces support auto-negotiation and most 10/100 Mb
interfaces with RJ-45 twisted-pair can run in full-duplex mode.
•Any network connected via an AUI port (Attachment Unit Interface), such as
on an external Ethernet transceiver, can run only in 10Mb half-duplex mode.
3.4 Mdi/MdiX : Sets a port connection to match the required send/receive cable
terminations from the far-end port. Click to view and select from Auto, Mdi, or
MdiX. The normal setting is Auto, where the auto negotiation protocol senses
and sets the port connection to Mdi or MdiX (straight or cross-over
respectively). Most RJ-45 Ethernet cables are Mdi. Note that if a port at the far
