System Configuration Via Dhcp - Hirschmann RS20 User Manual

Entering the IP Parameters
2.6 System configuration via
DHCP
The DHCP (dynamic host configuration protocol) responds similarly to the
BOOTP and additionally offers the configuration of a DHCP client via a name
instead of via the MAC address. For the DHCP, this name is known as the
"client identifier" in accordance with rfc 2131.
The device uses the name entered under sysName in the system group of
the MIB II as the client identifier. You can enter this system name directly via
SNMP, the Web-based management (see system dialog), or the Command
Line Interface.
On startup, a device receives its configuration data according to the
"BOOTP/DHCP process" flow chart
The device sends its system name to the DHCP server. The DHCP server
can then use the system name to assign an IP address as an alternative to
the MAC address.
In addition to the IP address, the DHCP server sends
– the tftp server name (if available),
– the name of the configuration file (if available).
The device accepts this data as configuration parameters
„Web-based IP configuration"). If an IP address was assigned by a DHCP
server, it will be permanently saved locally.
