Hello experts,
I have a doubt regarding the Certainty factor on ISE.
Let's suppose we have a default profiling rule which is Canon Device with one condition matching the Canon OUI and CF = 10 (Minimum CF = 10)
1st question : Now if I create a custom profiling rule with exactly the same rule, meaning the Canon OUI with CF = 10. Which one will match ? Is it alphabetic order or something else ?
2nd question : How the priority is done ? Let's suppose I have 2 profiling rules :
- The first one contains 2 conditions:
* the first with Canon OUI (CF = 10)
* the second one is the dhcp-class-identifier that has to match ABC (CF = 10)
* Minimum CF = 10
- The second one contains 3 conditions:
* the first with Canon OUI (CF = 10)
* the second one is the dhcp-class-identifier that has to match ABC (CF = 10)
* the third one with MAC address starting with XYZ (CF = 10)
* Minimum CF = 10
Which profiling rule will win ?
I hope I am enough clear :)
Thank you,
A.

On 1, I would avoid doing that. If you want preventing the profiler feed services updating the profiling policies without you reviewing the changes, you may opt for off-line updates instead. Otherwise, I believe either policy can be matched so it's not deterministic.
On 2, I believe you meant two different profiling policies -- one with 2 rules and the other 3 rules. If the endpoint matched on only the first 2 rules, then same as (1). If the endpoint matched on all three rules, then it will be profiled as the 2nd profiler policy.
