Filtering by MAC address

[Glenn Satchell]

Hi Olivier

This has been covered on the list in the past, but the general idea is 
to create a class that matches a substring of the cisco mac address. 
Then use two pools in each subnet: one allowed for the cisco devices, 
and one denying the cisco for everything else.

class "voip" {
   match substring(hardware, 0, 3);
}
subclass "cisco" aa:bb:cc;
# add more subclass lines if needed.

subnet ... {
   pool {
     range ...
     allow members of "cisco";
   }
   pool {
     range ...
     deny members of "cisco";
   }
}

regards,
