    Hi,

    got. question aboiut custom fingerprint creation. I've done tihs before but always with a bit of trepidation at the thought of overwriting endpoitns with a badly formed custom endpoint.
    Below are the details associates with a polycom ccx-500 phone.I always like to try having as many rules as possible  when dfining a custom fingerprint to make sure i dont overwrite  other devices.
    In this case I'm interested in changing the DHCP.Option12 line and. the LLDP.System Description line.

    For option 12,  I just want to  have contains "Poly", so would that be  CONTAINS ["Poly"],  why wouldnt it  be. CONTAINS "Poly". 
    For LLDP system description  I just want to check for Poly;CCX-CCX_500 so would that be CONTAINS Poly;CCX-CCX_500
    Again whats the difference between just stating things like the LLDP version?
    I know that in. Postgresql you can define an array of strings using ["string1","string2"] ...etc] perhaps thats the difference?
    Anyway, plan is to have a fingerprint for a CCX500  Polycom device  rather than a generic polycom ip phone. device
