This feature is advanced and should be used by only expert users in special situations.

Use this command to specify additional global DHCP server parameters that are not available with the service dhcp-server commands. The Vyatta router DHCP server commands are a subset of those that are available for DHCP server configuration. This command provides access to all DHCP server configuration parameters. More information regarding DHCP server configuration is located on the dhcpd.conf man page. To access the page, type the following at the Vyatta command prompt:

man dhcpd.conf

The Vyatta router does no validation before passing the parameter string to the DHCP server process (dhcpd). Because of this nonvalidation, it is imperative that the syntax described in the dhcpd.conf documentation be strictly followed. Failure to do so could result in a failure of the DHCP server. It is advisable to check the system log for errors when using these parameter strings. In addition, the show system processes command determines if the dhcpd process is still running.

The scope of these parameters is global. They apply to all shared-networks, subnets, and static-mappings unless parameters with a narrower scope are specified by using the shared-network-parameters, subnet-parameters, or static-mapping-parameters version of this command.

Multiple parameter strings can be specified. Each parameter string that is specified adds a separate line to the dhcpd.conf file.

Use the set form of this command to specify additional global DHCP server parameters.

Use the delete form of this command to remove additional global DHCP server parameters.

Use the show form of this command to display additional global DHCP server parameters.
