# DHCP Failover config

# Notes: In the past couple years, TCP ports 647 (primary) and 847 (peer) have
# emerged as the standard bindings for DHCP dhcp_global_failover It is worth noting that as
# recently as 2005, the dhcpd.conf(5) man page used ports 519 and 520 in its
# failover example, but 647 and 847 look like good choices as of 2008. However,
# the dhcpd.conf(5) man page says that the primary port and the peer port may be
# the same number.
