This read-only Integer32 is described as the retry interval in seconds for this SA, the duration between one retry and the next, with the fractional-second part held separately in the paired microseconds object. An admin reads this to understand the actual pacing of retransmissions in effect for a specific negotiation, useful when comparing behavior across SAs with different effective retry settings. For example, an admin comparing a sluggish dialup SA against a healthy site-to-site SA might find the dialup SA's retry timer value is much longer, worsening perceived connection delays.
