Module: CTRON-ETWMIM-MIB
OID (symbolic): CTRON-ETWMIM-MIB::etwClearNvramOnBoot
OID (numeric): 1.3.6.1.4.1.52.4.1.1.4.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When set to a 1, the system will clear all persistant objects, except for the download objects, from nvram on the next system boot
What is etwClearNvramOnBoot?
This is a one-shot trigger that, when set to 1, wipes all persistent configuration settings from NVRAM on the next reboot, deliberately sparing the firmware-download-related settings. It lets an admin reset a misconfigured module back toward factory defaults without losing its ability to still re-download firmware afterward. For example, an admin sets this to 1 before rebooting a module with a corrupted configuration, knowing the module will still remember its TFTP download parameters to re-fetch firmware if needed.
