CHAPTER 15: IMAGE FILE DOWNLOAD
15.4REMOTE RUNTIME DOWNLOAD
If the Runtime Download is interrupted, the Firmware Image in Flash memory will be erased. The EMM-E6 will continue to operate until it is either Reset or Powered OFF and ON.
After either of these events, the EMM-E6 can download a Firmware Image from a BootP server ONLY! The process of configuring a BootP Server is discussed at length in Cabletron’s “Installing and Using Remote LANVIEW for Windows”. Although Runtime Download is a powerful network operations & firmware management feature, careful consideration should be given to both the timing (best when network usage is lowest) and network stability (especially downloads over a WAN link) at the time of the planned download.
Table 15-2 provides a step by step procedure for downloading the firmware image file. This section provides specific MIB OIDs, their names, and the required setting for proper image file download. Refer to your specific MIB walking tool documentation for instructions on how to set MIB OID strings.
The Download OIDs for Cabletron products reside in Cabletron enterprise MIBs (group 52). The specific OIDs necessary to perform an image file download reside in the common download group under ctDL (Cabletron Download). The full OID string to reach this group is:
1.3.6.1.4.1.52.4.1.5.8.1
When performing the steps in Table 15-2 keep the following in mind:
•You must follow the steps in order.
•Enter the IP address of the tftp server in standard dotted decimal notation (e.g., 132.177.118.24).
•Enter the FULL path to the image file in the ctDLTFTPRequest OID, including the name of the image file (e.g., c:\tftpboot\EMME6.fls).
