What is jnxJsScreenSynFloodSrcThresh?

This read-only value reports the configured per-source SYN-flood threshold: the number of SYN segments per second from one source IP, regardless of destination, before the device starts dropping that source's connection requests. An admin reads this to confirm the source-based SYN-flood defense is tuned to the zone's expected client behavior.

Examples
