what are the rules for a tractor beam using on an enemy large ship?

does it work with 1 or like ion it needs 2??

It still gets the tokens (for -1 agility), but is immune to the barrel roll part. At the end of the round, all tractor beam tokens are removed.

Can you point where this is explained in the rules or FAQ please?

Note: the tractor movement has received errata that makes it optional.
