Templates, and networks bound to them, will have rulesets that are significantly more limited in terms of the classifications performed via NBAR. Due to technical limitations, the expanded NBAR rule set is not currently supported. Supported hardware and firmware versions are still required for this functionality.
Ahhhhh the MX. Love it.
*sarcasm*
NBAR works just fine in a template with SD-Internet policies , but doesn't work with anything else ☠️
