Where do you define a default SLA?

The documentation states that a Priority is NOT the same as a Service Level Agreement (SLA). The default Priorities can be set in the request form.

But where is the default SLA level set? I'm looking on the SLA configuration page, but not seeing where it's by default set to 4 hours.

I have four SLA's, High, Medium, Normal, Low and they are organized in that order.

There are no rules as of yet applied to any of these rules. The priority is user selectable, and technician changeable. But that's a priority, not an SLA level.

Email comes in, creating a ticket, with a SLA of 4 hours. (Normal) My default priority is set to Normal, but again, that's a Priority, not a SLA.

The SLA names don't seem to have a correspondence to the Priority names, as I created a priority called "Fake" and didn't see it show up in the SLA fields.

Where does the default SLA level get set?
