Description: This object reports the status of the TFTP client. If a TFTP session has never been active since the box has booted, the value 'ready' is reported. If a session is currently active, the value 'inProgress' is reported. If a session is not currently active, the status of the last active session is reported as 'succeeded' or 'failed'. If the status is 'failed' the object 'acosTftpFailReason' will contain the reason for the failure. If the status is 'failed' or 'succeeded', the object 'acosTftpOctetsRead' will contain the number of octets read.

What is acosTftpSessionStatus?

This OID reports the current state of the TFTP transfer, with possible values being 'ready' (no session active), 'inProgress' (transfer happening now), 'succeeded' (last transfer completed successfully), or 'failed' (last transfer had an error). A network engineer polls this to track upgrade progress and determine if a previous upgrade attempt succeeded or needs to be retried. A value of 'inProgress' means the device is actively downloading the firmware image right now.
