Hi Simon,
Thank you for the suggestions, but to add the subclasses statements into
the config I need to stop the service and start the service, when I get
multiple clients request it may lead to crash of my dhcp service because of
multiple stops and starts
do we have any way where I can include the statements into some other file
and include that into the main config file? or can we use any omapi to load
the statements dynamically without restarting the service
Thanks

Google is your friend...
?
Depending on what dhcpd version you're using, it sure looks like OMAPI classes
support exists.
?
https://kb.isc.org/docs/aa-01092
?
Since I can never get OMAPI to do what I want the first time (or even the
forty-third time), I'd recommend testing/tinkering on a VM/test server that's
non-production to see if it actually does what you want. :)

Hi Greg,
I am using the latest version of dhcpd 4.4.2 so I guess I can use this
concept, I tried checking the ISC documents but somehow I missed this page
but again thanks for the suggestion
>>I'd recommend testing/tinkering on a VM/test server that's non-production
to see if it actually does what you want. :)
---> Sure I will test it on my test server first
