ctDLOnLineDownLoad

Module: CTRON-DOWNLOAD-MIB

OID (symbolic): CTRON-DOWNLOAD-MIB::ctDLOnLineDownLoad

OID (numeric): 1.3.6.1.4.1.52.4.1.5.8.1.16

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: During normal operation this object has the value of 1.

By setting this object to a value of forceDownLoad(2) an image download via TFTP will be performed, ctDLNetAddress specifies the TFTP server and ctDLFileName specifies the file name of the image on the TFTP server.

By setting this object to a value of forceDownLoadReset(3) an image download via TFTP will be performed, ctDLNetAddress specifies the TFTP server and ctDLFileName specifies the file name of the image on the TFTP server. A reset will be forced upon successful completion of the download.

By setting this object to a value of downLoadConfiguration(4) the specified configuration file will be downloaded, verified, and, if valid, committed to NVRAM, if valid. A reset will be forced upon successful completion. ctDLNetAddress specifies the TFTP server and ctDLFileName specifies the name of the configuration file on the TFTP server.

By setting this object to upLoadConfiguration(5), the contents of NVRAM will be uploaded via TFTP to the specified file on the specified TFTP server. ctDLNetAddress specifies the TFTP server and ctDLFileName specifies the name of the configuration file.

What is ctDLOnLineDownLoad?

This is a mode-selection field that triggers different online operations: normal operation, forcing a TFTP image download, forcing a download followed by a reset, or uploading/downloading a configuration file. It is the central object an admin uses to kick off a remote firmware or configuration transfer without waiting for a scheduled reboot. For example, setting this to forceDownLoad(2) while ctDLNetAddress and ctDLFileName point at a staged image starts an immediate TFTP firmware pull.
