Start updating the firmware of the specified target module. Using execute or execute-with-reboot will cause the SNMP client to wait for the firmware update to complete. Using execute-nowait or execute-with-reboot-nowait will not cause the SNMP client to wait for the update to complete. Instead it will flash the firmware in the background. Note 1: If the execute-with-reboot or execute-with-reboot-nowait option is selected, the target will reset after a successful flash. This option is only valid if the firmwareUpdateTarget object is set to managementModule. Note 2: If flashing from a remote file, then both firmwareUpdateServer and firmwareUpdateFileName must be set. Otherwise if flashing via the legacy method using a tftp server, then both firmwareUpdateTftpServer and firmwareUpdateFileName must be set. Note 3: Depending on the target, it might take up to several minutes for the flash update to complete. Do not reset the target until the control has been returned. At this point, the results will be displayed. Note 4: Use firmwareUpdateStatus to confirm the status of the last firmware update initiated by SNMP method. The Management Module must be restarted for the new firmware to take affect. Note 5: If data encryption is currently enabled on this MM, and you update the MM firmware to a level which does not support data encryption, you will lose all your configuration settings as a result. Note 6: Since some I/O Module types use the AMM TFTP server for firmware file transfer during the firmware update process, the tftpEnable MIB object must be set to enable prior to updating the firmware for these modules. Note 7: If IPv6 address(es) have been configured for one or more interfaces/protocols/services on this AMM, when you update the firmware to a level which does not support IPv6, all IPv6 connectivity will be lost, and services/interfaces for which an IPv6 address was configured may not function properly. You will be required to reconfigure these services/interfaces. NOTE: Value returned for the GET command is meaningless for this MIB object.
