Description: The value 'noAction' is always reported in a GET.

The box will request from the server the file identified in object 'acosTftpAcosName'.

What is acosTftpUpgradeACOS?

This OID is a write-only action trigger that, when set to 'upgradeACOS', initiates an immediate firmware upgrade of the ACOS operating system. A network engineer uses this to remotely start the upgrade process after staging the image file on the TFTP server. Setting this to 'upgradeACOS' causes the device to connect to the TFTP server, download the file specified in acosTftpAcosName, and begin the upgrade sequence.
