System Configuration Via Dhcp - Hirschmann Power MICE User Manual

Entering the IP parameters
2.6 System configuration via
DHCP
The DHCP (dynamic host configuration protocol) responds similarly to the
BOOTP and offers in addition the configuration of a DHCP client with a name
instead of the MAC address. For the DHCP, this name is known as the "client
identifier" in accordance with rfc 2131.
The Switch 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, an Switch receives its configuration data according to the
"BOOTP/DHCP process" flow chart
The Switch sends its system name to the DHCP server. The DHCP server
can then assign an IP address as an alternative to the MAC address by using
the system name.
In addition to the IP address, the DHCP server sends
– the tftp server name (if present),
– the name of the configuration file (if present).
The Switch accepts this data as configuration parameters (see
figuration via the Web-based Interface" on page
If an IP address was assigned by a DHCP server, it will be permanently sa-
ved locally.
