As soon as this setting is saved, the target device uses this identifier as DHCP option 61. If no
identifier is set, the MAC address of the device is used. The parameter can be changed also
afterwards in operation via SICAM WEB.
In order that the autoconfiguration works, at least the DHCP options 66 and 67 must be given.
The TFTP Server Name can be either an IP address or likewise a Full Qualified Domain
Name (see DNS), if one or more DNS servers are set or are supplied via DHCP.
The target device connects to the TFTP server indicated in DHCP option 66, and downloads
the configuration file indicated in DHCP option 67. The file is checked upon integrity by means
of a cryptologic hash function that is calculated over the file. The result is compared with the
hash value in the filename:
·
if the file is valid, it is accepted and all settings in the target device are adapted
·
with different results, the file is deleted and no changes are carried out
Depending on the setting of the "Lease Time" on the DHCP server, the configuration can be
updated. If the same file name is given, the target device keeps its settings. If another name is
given, the file is downloaded again and the settings are accepted.
