This value sets how many times the network-side UME retries an ILMI poll request after detecting a loss of ILMI connectivity before giving up, with 0 falling back to a default of 4 retries. An admin raises this on links where occasional ILMI poll loss is expected, such as a noisier physical path, to avoid prematurely declaring ILMI down, or leaves it at the default 4 for typical links. For example, leaving lportIlmiPollRetry at 0, the default of 4 retries, means the switch attempts four ILMI poll retries before concluding ILMI connectivity is genuinely lost and reporting lportIlmiOperStatus as down.
