This read-create value, in milliseconds, sets how long this switch waits on a given VSAN before dropping frames that have not been delivered in the order they were transmitted, and it must always be greater than the switch-level fcSwitchLatency value. An administrator tunes this to balance how aggressively out-of-order frames are discarded against the fabric's real round-trip latency on that VSAN. Note that this VSAN-specific value tracks the device-wide fcNetworkDropLatency setting whenever that changes, so an admin adjusting the global timer should expect this per-VSAN value to move with it.
