This read-write value sets how many seconds, 1 through 9, the switch buffers before sending a Frame Relay LMI asynchronous status update, or an ATM OAM alarm, to filter out rapid, transient LMI events from generating a flood of notifications, with 0 meaning immediate unbuffered delivery and 255 meaning updates are suppressed entirely. An admin raises this modestly on flappy circuits to prevent a storm of async status changes from overwhelming attached CPE or NMS systems, while keeping it low or at 0 where fast notification of real changes matters most. For example, setting lportLMIDelay to 3 means a PVC status flap gets buffered for up to 3 seconds before being reported, potentially coalescing multiple rapid flaps into a single notification instead of several.
