Struggling with classes not work

[Patrick Fortin]

Hi

you could activate log debug to see the content of the data you are 
trying to match

for example I used this to see the models than was able to match the 
correct data

log(info, concat("debug: mac= ", binary-to-ascii(16, 8,":", option 
dhcp-client-identifier)," modnum= ",option SA.modnum," devtype= ",option 
SA.devtype ," swver= ",option SA.swver));

adjust for your needs
