Downloading Releases and Patches into the Router
The LOADER module is responsible for loading and storing releases, patches
and other files into either NVS or FLASH. The LOADER module uses the
Trivial File Transfer Protocol (TFTP), Hypertext Transfer Protocol (HTTP) or
ZMODEM over an asynchronous port, to retrieve files from a network host.
The FFS and NVS modules are used to create, write and destroy release and
patch files.
The loader can be configured with the command:
SET LOADER
This command sets default values for the name of the file to load, the network
host to load it from, and the memory location in which to store the file. These
default values can be overridden when the load actually takes place. A time
delay between initiating a load and the start of the load can also be configured.
The configuration of the LOADER module can be displayed with the command:
SHOW LOADER
This shows the default configuration for the LOADER module as well as the
status of any current file transfer.
To actually initiate a load, use the command:
LOAD
This command will use either the default values for the LOADER module or
the values specified on the command line. The command:
SHOW LOADER
displays the progress of the load. The current load can be stopped at any time
using the command:
RESET LOADER
leaving the LOADER module ready to load again. Only one file can be loaded
at a time. Another load can not be initiated while loading is in progress.
Once the release or patch file has been loaded, its presence can be checked
with the command:
SHOW FILE
for files in FLASH, or using the command:
SHOW PATCH
for files in NVS. A release or patch file can be removed with the command:
DELETE FILE
for files in FLASH, or with the command:
DESTROY PATCH
for files in NVS.
Files to be loaded by the LOADER module must be resident on a TFTP server
accessible via the network, or accessible via the ZMODEM protocol over an
asynchronous port. Release and patch files are ASCII files, and consist of a
header followed by a sequence of Motorola S-records containing the actual
code for the release or patch. The header has a standard format, which
provides information about the release or patch to the router.
