Viewing DHCP settings

The Fabric Services System maintains a set of properties that govern the way it, and nodes it manages, interact with a DHCP server. These properties include a DHCP default lease time, and a DHCP maximum lease time. By default, both are set to seven days (86,400 seconds).

These properties are stored in a pair of files on the Fabric Services System server:

  • dhcpd.conf (for ipv4)
  • dhcp6.conf (for ipv6)

For example:

# dhcpd.conf
log-facility local7;
default-lease-time 604800;
max-lease-time 604800;
shared-network fss {
}
# dhcpd6.conf
log-facility local7;
default-lease-time 604800;
max-lease-time 604800;
shared-network fss {
}
