2.6 System Configuration via
DHCP
The DHCP (Dynamic Host Configuration Protocol) is a further development
of BOOTP, which it has replaced. The DHCP additionally allows 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.
During startup operation, a device receives its configuration data according
to the "DHCP process" flowchart
The device sends its system name to the DHCP server. The DHCP server
can then use the system name to allocate an IP address as an alternative to
the MAC address.
In addition to the IP address, the DHCP server sends
 the netmask
 the default gateway (if available)
 the tftp URL of the configuration file (if available)
The device accepts this data as configuration parameters
