IP Alive menu command (in access point mode only)
Table of monitored devices
In the "IP Alive" drop-down list box, you decide whether connection monitoring is enabled or
disabled. Only connections to IP addresses for which the check box in the "Sel" column is
selected will be monitored.
You can delete entries in the table by selecting the relevant check box in the "Del" column
and clicking the "Set Values" button. You can create new list entries after clicking the "New"
button. You can then enter the MAC address and the monitoring time.
Monitoring independent of the port
With IP-Alive, you specify a monitoring time for an IP address and a port. If you do not want
to monitor a particular port but rather only the data traffic from a particular IP address, simply
enter 0 in Port. This resets the monitoring with each frame from this IP address.
System event for connection abort
You can specify how the SCALANCE W78x reacts to change in the IP-Alive status in the
System > Events menu.
Note
The IP-Alive function is not available in iPCF mode.
Note
If the IP Alive function does not detect any data traffic for the specified time, the status of the
IP address is set to "Offline" and the error status activated. The error status must be
confirmed before the IP Alive function sets the status for active data traffic back to "Online".
