Attachment 1 - DHCP configuration file /etc/dhcpd.conf

Attachment 2 - DHCP startup messages

Attachment 3 - FEE64 startup messages from /var/log/messages

Note

1) dhcpd service is not listed by services tool which we have usually used to restart dhcp following
changes to the configuration. Currently we restart dhcpd as follows

kill -SIGTERM <pid dhcpd>
/usr/local/sbin/dhcpd

2) significant delays (~6 and ~9 minutes) starting aida07 and aida05, otherwise appears to be normal startup
