After serving as a quaestor in Sicily, he accepted another commission as the legatus legionis or commander of the Legio IV Scythica in AD 62, stationed at Zeugma in Syria.

At one point Vettonianus found himself commanding the legion under the leadership of Lucius Caesennius Paetus in the Roman–Parthian War of 58–63.

It may be that as similar positions, it made sense to group them together in the inscription, or Vettonianus was adjunct curator aquarum to the man usually considered his predecessor, Manius Acilius Aviola.

[7] While governor of Moesia Superior, Vettonianus participated in the Dacian Wars with such valor he was awarded the dona militaria appropriate for an ex-consul.

[10] His possible descendants include Titus Pomponius Antistianus Funisulanus Vettonianus, suffect consul in the year 121, and Funisulana Vettulla, the wife of Gaius Tettius Africanus Cassianus Priscus, prefect of Egypt.
