PROFINET Port settings:
 Select the port for which you want to set the DCP mode in detail, and in
the column DCP Mode, select
– none:
The device sends received DCP frames. However, the CPU does not
process them yet, it still generates DPC frames. The port does not
send any DCP frames which were received at another port.
– ingress:
The device sends received DCP frames. The CPU processes received
DCP frames from this port, but does not generate any. The port does
not send any DCP frames which were received at another port.
– egress:
The device sends received DCP frames. The CPU ignores frames
received from this port and generates them as needed.
– both:
The device sends received DCP frames. The CPU processes received
frames and generates them as needed.
The default setting is both.
Note: If you connect 2 switches which are to be located in separate DCP
domains, change the DCP mode of the ports involved to none or to
ingress on both switches. This ensures that neither of the switches
receives or forwards DCP frames.
 Select the port for which you want to set its PHY module to the fast start
mode, and select from the following in the column Fast Start Up:

disable to set the normal start mode,
 enable to set the fast start mode.
Note: The setting enable only becomes effective if the automatic
configuration of the port (Autoneg) is switched off
Configuration").
The default setting is disable. If a port does not support the fast start
mode, the device will show unsupported in this column.
