Description This command allows you to configure the DHCP server using the options detailed in
RFC2132. To display a list of available options, use the command DHCPSERVER LIST
OPTIONS.
The heading of each option in the list contains the option identifier and the required value
(in italics) for that specific option. The following is an extract from the option list:
• option auto-configure flag;
This option, based on RFC2563, controls whether clients on this subnet are allowed to
perform the IP address auto configuration.
It only applies in cases where the DHCP server is unwilling or unable to supply an IP
address lease. In this case, if this option is set to 1, then the DHCP server will not inter-
vene to prevent clients from using auto-configuration to determine an IP address. If this
option is set to 0, the DHCP server will explicitly forbid the use of IP address auto-con-
figuration on the network.
If this option is not explicitly configured, then it will be assumed that auto-configuration is
allowed on the network.
Options The following table gives the range of values for each option that can be specified with
this command and a default value (if applicable).
Option Description Default Value
name An existing subnet. To display subnet names, use the
DHCPSERVER LIST SUBNETS command.
