HTTP - Network & Security DHCP Settings
Click the “Apply” button and reboot the CS121 with the “Save, Exit & Reboot” function.
Fallback address:
If the DHCP server will not be available, just reboot the CS121 to use the
fallback address. This address is equivalent to the settings of the local address in the menu
„Network & Security Settings“. When DHCP will be available again, just reboot the CS121 to
use the DHCP address.
4.2.5
The CS121 with ICMP Check
From the firmware version 4.26.x the CS121 is able to answer and send ICMP polls, to check
the quality of the network and, in need, can reboot itself.
Figure 19:
HTTP - Network & Security ICMP Check
You can enter up to 3 addresses, which will be checked via ICMP. Before the ICMP Check
works, at least one of the entered addresses must be available. Only after successful ping the
task is active. If all 3 addresses are not be reachable, the CS121 will reboot itself after 750
seconds (default). We recommend to use the IP address of a gateway and 2 more addresses,
which are reachable steady. If you enter only 1 or 2 addresses, the amount of the checkable
addresses is reduced and the possibility to initiate a reboot will increase unnecessarily,
because less addresses are at hand for the check of the network quality. If the CS121 will
reboot itself often at enabled ICMP check, an analysis of the network is required (e. g.
Wireshark), to be able to find the reason. If this should not be possible, you should disable all
ports at your switch, which are not required for the CS121, to avoid unnecessarily network
traffic. Please take a look into chapter Appendix D., D.9 for further information.
Note:
The CS121 supports 3 functions of ICMP via RFC 792:
0
– Echo reply
3
– Destination unreachable
8
– Echorequest
4.2.6
Function hide of HTTP links
