Thanks Simone this works!
I'm trying to go to the perfect solution :-) so I have still a question.
Is there a possibility to get the boolean OR operation with tags?
I give for a mac and hostaname some ip
For the same mac with other hostname an other ip
And for the rest I want normal dhcp operations...
dhcp-match=set:hostname1-ok,12,laptop
dhcp-mac=set:mac1-ok,XX:2e:5f:81:XX:XX
tag-if=set:host1-ok,tag:hostname1-ok,tag:mac1-ok
tag-if=set:host1-mac-only,tag:!hostname1-ok,tag:mac1-ok
dhcp-range=tag:host1-ok,10.0.0.220,10.0.0.220
dhcp-range=tag:host1-mac-only,10.0.0.230,10.0.0.230
Now how can I to a tag which is set if one of this tags above are set?
As I see tag-if does set tag only if all tags are set and I want
set a tag if host1-ok is set OR host1-mac-only is set ...
so I can use this tag for normal operations or is there an other solutions?
De-Morgan's theorem to the rescue!
A OR B == NOT ( (NOT A) AND (NOT B) )
dhcp-range=tag:!host1-mac-only,tag:!host1-ok,<normal address range>
Cheers,
Simon.
Thanks a lot
Beat
