Hello all,
I currently have a home grown IPAM that generates a class of allowed mac
addresses for use in various privileged address pools. Something like this:
class "coolkids" {match hardware;}
subclass "coolkids" 1:22:33:44:55:66:77;
subclass "coolkids" 1:88:99:AA:BB:CC:DD;
...
What I want to do is allow a specific group of devices in addition to
these, but using the vendor id instead of entering their mac addresses into
the IPAM.
class "coolkids" {
match if substring (option vendor-class-identifier, 0, 7) = "abcedfg";
}
I know I can do this by using 2 separate classes and adding a second "allow
from" statement to each pool, but the pools are dynamically generated by
the IPAM and there be dragons in that code. I know, I wrote it a decade
ago...
Does anyone know of a clever way to build up a class with two different
match conditions?
Andrew
