Cisco Cisco Prime Network Analysis Module Software 5.1 インストールガイド

During software upgrades, you use the Bootloader, a small set of system software that runs when the 
system first powers up. The Bootloader loads and runs the NAM application. The bootloader might 
optionally load and run the helper image on flash memory. 

Upgrading software involves installing, configuring, and starting a helper image. The helper, in turn, 
starts the NAM installation wizard, which installs the software. 

Plan software upgrades for times when you can take all applications that run on the host router out of 
service or offline.

The NME-NAM-120S contains three NAM software images:

Bootloader image in flash memory—Use to specify whether to boot the NAM application image or 
the helper image

Helper image in flash memory—Use to recover NAM software images

NAM application image on the hard drive—Source of the NAM and NAM CLI

NAM software upgrades are available in two forms:

Images—Full image releases that are installed from the helper image. Full image upgrades are 
typically used to update the NAM application image, and if necessary and recommended by 
technical support, you can also use the helper image to upgrade the bootloader image or helper 
image.

Patches—Incremental updates to software versions that are installed with the patch NAM CLI 
command. Patches are available only for the NAM application image.

Perform one of the following procedures in this section, depending on whether you are adding a patch 
to your NAM application or are performing a full software image upgrade:

Download the NAM software image from Cisco.com

Copy the image to an FTP server.

(Optional) Have available the IP address of your TFTP file server.
