Changing the configured port status with loop detection
The configuration of the port status can be changed with the "Loop Detection" function. If, for
example, the administrator has disabled a port, the port can be enabled again after a device
restart with "Loop Detection". The port status "link down" is not changed by "Loop Detection".
DCP forwarding
Applications
The DCP protocol is used by STEP 7 and the PST Tool for configuration and diagnostics.
When shipped, DCP is enabled on all ports; in other words, DCP frames are forwarded at all
ports. With this option, you can disable the sending of these frames for individual ports, for
example to prevent individual parts of the network from being configured with the PST Tool
or to divide the full network into smaller parts for configuration and diagnostics.
All the ports of the device are displayed on this page. After each displayed port, there is a
drop-down list for function selection.
