Identifies the connection duplex mode:
Both devices can send data to each other
at the same time
Only one device can send to the other at
a time
The duplex setting must match that of the device
to which this port is connected.
You only need to select this option if you have
chosen manual Ethernet settings, as described
above.
Indicates whether this Ethernet port is connected
to or disconnected from the network.
Shows the speed (10/100/1000 Mbit/s) of the
network connection to the MCU on this port.
This value is negotiated with the device to which
this port is connected or based on your manual
configuration, depending on the settings you
chose above.
Shows the duplex mode (full/half duplex) of the
network connection to this port.
This value is negotiated with the device to which
this port is connected or based on your manual
configuration, depending on the settings you
chose above.
Shows the fixed hardware MAC (Media Access
Control) address of this port.
This value cannot be changed and is for
information only.
Displays a count of the total number of packets
sent from this port by the MCU. This includes all
TCP and UDP traffic.
When troubleshooting connectivity issues, this
information can help you confirm that the unit is
transmitting packets into the network.
Displays a count of the total number of packets
received by this port of the MCU. This includes
all TCP and UDP traffic.
When troubleshooting connectivity issues, this
information can help you confirm that the unit is
receiving packets from the network.
These fields display further statistics for this port.
