Autoconfiguration
SICAM CMIC provides the option of being configured automatically by means of a complete
autoconfiguration file via DHCP service. The autoconfiguration file is a previously generated
SICAM CMIC backup (see 5.3.2,
Note
If a SD card generated through copy is used, please make sure that the file dhcpid is deleted (located in
AUTOCONFIG folder).
The selection of the autoconfiguration resides in the directory tree under
SICAM CMIC | Master module | AU common settings
(the checkbox Show all parameters must be activated).
With the expert parameter
In a network with DHCP server, the DHCP server defines the IP address on X1. If the DHCP
server is no more available, the target device can be accessed via X1 with the IP address
169.254.0.1, if the "lease time" of the DHCP server is already terminated. Otherwise the IP
address from the DHCP server is used until the termination of the time. The time is defined by
the DHCP server.
Note
DHCP can be easily disturbed and manipulated because DHCP clients accept any DHCP server.
The accidental activation of a DHCP server, for example by a simple DSL router or wireless router on de-
livery status can largely paralyze a network. That may respond faster than the foreseen DHCP server and
thereby distributes invalid configurations.
On the DHCP server, corresponding DHCP options must be configured:
Option 6:
Option 61:
Option 66:
Option 67:
