DHCP Server Operation
for DHCP clients.
filename
filename "
filenam
e”;
The
filename
statement can be used to specify the name of the initial boot
file which is to be loaded by a client. The filename should be a filename
recognizable to whatever file transfer protocol the client can be expected to
use to load the file.
server-name
server-name " nam e";
The
server-name
statement can be used to inform the client of the name of
the server from which it is booting.
Name
should be the name that will be
provided to the client.
next-server
next-server server-nam e;
The next-server statement is used to specify the host address of the server
from which the initial boot file (specified in the filename statement) is to be
loaded. Server-name should be a numeric IP address or a domain name. If
no next-server parameter applies to a given client, the DHCP server’s IP
address is used.
fixed-address
fixed-address
IP-address
[,
IP-address
... ];
The fixed-address statement is used to assign one or more fixed IP
addresses to a client. It should only appear in a
host
declaration. If more
than one address is supplied, then when the client boots, it will be assigned
the address which corresponds to the network on which it is booting. If
none of the addresses in the
fixed-address
statement are on the network on
which the client is booting, that client will not match the
host
declaration
containing that
fixed-address
statement.
dynamic-bootp-lease-cutoff
dynamic-bootp-lease-cutoff
dat
e;
The
dynamic-bootp-lease-cutoff
statement sets the ending time for all leases
assigned dynamically to BOOTP clients. Since BOOTP clients have no way
of renewing leases, and do not know that their leases could expire, the
DHCP server assigns infinite leases to BOOTP clients. However, it may
make sense in some situations to set a cut-off date for all BOOTP leases.
