1. String 4 (C): 2nd fret, index finger (barre), D
2. String 3 (G): 2nd fret, index finger (barre), A
3. String 2 (B): 3rd fret, middle finger, D
4. String 1 (D): 2nd fret, index finger (barre), E
5. String 5, the short g: open, G, not in the chord

Sounds: D A D E  ·  Asus4 is A, D, E (1 · 4 · 5)

The 5th string: the short g adds the ♭7 over Asus4, a colour rather than a clash.

With a capo: on the 2nd fret it’s 0 0 1 0 (frets counted from the capo), an open Gsus4 shape. Spike the 5th string at the 7th fret to keep it in tune with the capo.

C Tuning tuning: gCGBD, the short 5th string first, then strings 4 to 1.
