Hi Niall,
Thank you for your reply.
class “mytest” {
match option dhcp-client-identifier;
}
It seems that I should change the class definition to match either option dhcp-client-identifier or hardware.
class “mytest” {
match pick-first-value (option dhcp-client-identifier, hardware);
}
Thanks,
Jim

Is this a DHCP sever software bug or something else?
Whenever I’ve been surprised by behaviour like this,
it’s been due to a subtle bug in my configuration,
and never to a server software bug.
You show us
subclass "mytest" 1:74:A7:11:22:33:44;
but I can’t see your definition for
class “mytest” { … }
so can’t tell what the value in your subclass
statement is being matched against.
It’s been a while since I’ve needed to configure and run an ISC DHCP server,
so I had to check the relevant section of the documentation:
