Is Swiss Pass valid b/w Interlaken Ost to Jungfrau

Hi,

I am travelling to Interlaken and need to go to Jungfrau.



I will buy a swisspass for 4 days starting from 27th September to 30th September.



I want to travel from Interlaken Ost to Jungfraujouch.



Will my Swiss pass be valid for this journey or do I need to buy separate tickets for the journey (if yes, do I get any discount)?
Thanks in Advance.
