Hi Marcin,

Right now we only need IPv4.

But what we need is the ability to send a different boot file name - not just option 67 but the legacy BOOTP file name as well. The relevant config from isc-dhcpd looks like this:

host cm94fbb2991080 {
  hardware ethernet 94:fb:b2:99:10:80;
 
  option bootfile-name "CM-10-30.cfg";
  filename "CM-10-30.cfg";
}

In CMTS systems the modem speed profile is set via this boot config file, so this is an important feature.



Thanks!

Hi, it seems the dhcp4_options table in the MySQL schema has been
designed, but not implemented in the code. I tried setting some options
in the database, didn't work. I checked the code, the dhcp4_options
table is not referenced anywhere.

I need to reference different cable modem boot files by host entry for a
CMTS deployment - can I do this with classes and the MySQL hosts table?


Jawaid,

The Host Reservation feature was designed last year and this design
indeed included MySQL schema that allows for storing options. This
schema was created but, due to tight schedules last year, we didn't
manage to fully implement Host Reservations. Therefore, even though you
can put options in the SQL database the server wouldn't actually use
them (as you pointed out). Our goal for next release is to implement
some missing features in Host Reservations, which includes specifying
options for particular hosts.

As for your deployment, what are the DHCP options that you're going to
send to DHCP clients? In addition, are they v4, v6 or both?
