== Create custom template fragments ==
==customize the lease duration==
You can customize the lease duration for the dhcp server ('''dhcpd''') in SME using these instructions.
You can customize the lease duration for the dhcp server ('''dhcpd''') in SME using these instructions.
The commands below will create custom template fragments for <tt>default-lease-time</tt> and <tt>max-lease-time</tt>, re-generate <tt>/etc/dhcpd.conf</tt>, and restart the '''dhcpd''' service in order to activate your changes.
