I am willing to bet that you didn't load up the classifications when you iinitialized your policy within IDSPM. One way to tell is click on the Classifications tree node for the policy. Do you see classification details? if not, you will need to initialize the policy with a new default policy or initialize it with an existing policy where all of the rules and .conf files including classifications.conf are in the same directory.

Hi
I have problem like that with "include classification.config" option in configuration file.
In this option path to “classification.config” is not absolute. And when starting snort, he can't find this file.
I tried to change string "include classification.config" to "include /etc/snort/classification.config".

After this, snort starting successfully.
