This read-write value sets how often, in seconds, 1 to 255, the network-side UNI Management Entity, UME, generates ILMI, Integrated Local Management Interface, polls on this port, with a special value of 0 falling back to a default 5-second polling period. An admin adjusts this to control how frequently ILMI-based auto-configuration and status exchange occurs between the switch and connected ATM equipment, balancing responsiveness to configuration changes against signaling overhead. For example, leaving lportIlmiPollTimeout at 0 gives the standard 5-second ILMI polling cadence, while setting it to 30 would reduce ILMI signaling frequency at the cost of slower detection of ILMI-reported changes.
