This read-write field turns the ILMI function on or off administratively for this port, controlling whether the switch even attempts to run the ILMI auto-configuration and management protocol on this ATM interface at all. An admin disables this on ports connected to equipment that does not support or should not run ILMI, to avoid generating ILMI polls that will simply go unanswered. For example, connecting to legacy or simple ATM CPE that has no ILMI support would call for setting lportIlmiAdminStatus to disabled(2) to stop the switch from wasting cycles polling for an ILMI response that will never come.
