This read-only INTEGER provides, per its source description, a further explanation of what went wrong when a command completed unsuccessfully, with specific codes like unable, unrecognizedCommand, slotEmpty, noResponse, unsupportedCommand, deviceDisabled, testFailed, userInterfaceActive, and pendingSoftwareDownload; for tests, a bit-mapped sub-test result is available separately in the status table. Admins check this code after seeing a failure in ipgwCmdResult to understand the specific root cause without needing console access to the card. For example, a code of userInterfaceActive(58) would explain that a command failed because someone is actively using the card's local user interface, blocking the remote command.
