During the first campaign against the Dacians, after the Second Battle of Tapae, Trajan dispatched Sura and Tiberius Claudius Livianus to negotiate peace with the Dacian king Decebalus. Nothing was accomplished, since Decebalus did not meet them, but sent envoys instead on this occasion. Nevertheless, because the Romans captured key strongpoints in the mountains and Decebalus' sister was captured, the Dacians agreed to the terms the Romans demanded and peace was agreed to between the Romans and Dacians. For this, Sura was appointed to a second consulate as "consul ordinarius" in 102 as the colleague of Lucius Julius Ursus Servianus. He also participated in Trajan's second campaign against the Dacians; while his role in that war is undetermined, it was important enough for Sura to be awarded triumphal ornaments and a third consulate in 107 with Quintus Sosius Senecio as his colleague.
