This read-only Integer32 is described as the limit of retry counts for this specific SA, the negotiated or applied value derived from the server parameters for this active session. An admin reads this per-SA value to confirm what retry behavior actually applies to a live negotiation, as opposed to the general server-wide default that might have been overridden. For example, an admin troubleshooting a dialup SA that gave up too quickly would check this per-SA retry limit to see if it was lower than the server-wide default.
