Using the CNS NetFlow Collection Engine Installation Script
The CNS NetFlow Collection Engine is distributed on CD-ROM. Updates are made available at
http://www.cisco.com. When installing from the CD-ROM:
• Run the install script setup.sh in the root directory of the CD-ROM.
When downloading an update:
• Identify a partition such as /tmp that you can use to hold the CNS NetFlow Collection Engine
download and image files.
Note You should verify that the partition you plan to use contains at least 200 MB of free disk space. This
partition must be large enough to hold the gzipped download file, distribution files, and the temporary
work files created by the installation script while it is installing the CNS NetFlow Collection Engine.
• Unzip and untar the download file.
• Run the installation script NFC_setup.sh.
The CNS NetFlow Collection Engine installation script makes the installation process as easy as possible
by automatically handling new and upgrade installation issues. The installation script searches for files
from a previously installed version of CNS NetFlow Collection Engine. If it detects a previously
installed version, it preserves existing data and configuration files. Preserving the configuration files
retains any additions or changes to the CNS NetFlow Collection Engine resource definitions or
parameter settings that you might have made while using the previously installed version of CNS
NetFlow Collection Engine.
Later in the installation process, the installation script allows you to specify whether you want to use the
existing configuration files, or use the new configuration files. Depending on your choice, the unused
files are saved in case you need them later.
The installation script also saves existing log files before clearing the logs directory during an upgrade.
Note If the installation script does not find files from a previously installed version of CNS NetFlow
Collection Engine, the installation is a first-time installation and is basically the same as for an upgrade
installation, but with fewer prompts from the installation script. The installation script prompts you for
responses to any required steps.
