Each option declaration is terminated by a semicolon ;. You can specify multiple subnets here. The parameters defined outside the braces apply globally to all the clients. For example :.

However, as these interfaces do not have a normal hardware Ethernet address, a different method of specifying a unique identifier for the IPoIB interface must be used. The DHCP server host construct supports at most one hardware Ethernet and one dhcp-client-identifier entry per host stanza. However, there may be more than one fixed-address entry and the DHCP server will automatically respond with an address that is appropriate for the network that the DHCP request was received on.
In order to find the right dhcp-client-identifier for your device, you can usually use the prefix ffc and then add the last 8 bytes of the IPoIB interface which happens to also be the 8 byte GUID of the InfiniBand port the IPoIB interface is on. On some older controllers, this prefix is not correct. The hardware-type corresponds to the initial ff: of the ID, the rest of the ID is then quoted exactly as it needs to appear in the DHCP configuration file. All subnets that share the same physical network should be declared within a shared-network declaration as shown in Example Parameters within the shared-network , but outside the enclosed subnet declarations, are considered to be global parameters.
For example, shared networks, subnets, and hosts can be grouped. You can use the provided example configuration file as a starting point and add custom configuration options to it.
To copy this file to the proper location, use the following command as root :. For a complete list of option statements and what they do, see the dhcp-options 5 man page. Lease Database. Do not change this file. DHCP lease information for each recently assigned IP address is automatically stored in the lease database. The information includes the length of the lease, to whom the IP address has been assigned, the start and end dates for the lease, and the MAC address of the network interface card that was used to retrieve the lease.
Your DHCP server should now be running. If there are any issues, you can start dhcpd in a debugging mode using the -d option.
The dhcpd daemon also logs messages to the system log, slogger. Copyright Community.
