itpconfig uses ILOM Notification Alert Rule 15 to set up the trap forwarding. If this alert rule is in use, itpconfig fails with error code 83 . This error is caused when you try to run itpconfig when ILOM Notification Alert Rule 15 is already defined on the system.
To work around this, set the destination IP address of ILOM Notification Alert Rule 15 to 0.0.0.0.
