SV: Assigning fixed and dynamic addresses via DHCP based on Option 82 and vendorclass

[Anders Rosendal]

Is it possible to write more then two conditional statements in a match if(...). 

I.e.

class "A" {
	match if(aa = X and bb = Y and cc = Z);
}

Class "B" {
	match if(aa = X and bb = Y and not cc = Z);
}

Or something similar??

We can't assume anything on this list !

Yes

No

So in a case like this, where you have "class a does x, class b does 
y", then you have to make sure that the selection criteria for "a" 
and "b" are mutually exclusive if you want "x" and "y" to be.
