Chapter 2 Installing CNS NetFlow Collection Engine

Installing on a Solaris or HP-UX Platform

Step 9 If a previous installation was detected, you are prompted whether to use old configuration files or to install new configuration files:

Please choose one of the following..

(1) Install new default configuration files

(Your existing configuration files have been saved in the config/old subdirectory should you want to refer to them later)

(2) Retain existing configuration files

(New default configuration files will be saved with '.default' extensions should you want to refer to them later)

Please choose: 1

If option 1 is selected, previous files are kept in the NDC_DIR/config/old subdirectory as indicated. If option 2 is selected, new configuration files are saved with the .default suffix, and the previous installation’s configuration files are retained.

a.When upgrading to CNS Netflow Collection Engine, Release 5.0 from version 4 or earlier, the previous configuration is not backwards compatible so this prompt is not displayed. A tool is provided to assist the user with migrating their previous configuration. See Appendix G, “CNS NetFlow Collection Engine Migration Tools.”[link] for additional details.

b.When upgrading to CNS Netflow Collection Engine, Release 5.0.2 from version 5.0 or 5.0.1 and option 2 is selected, a migration script is run to automatically migrate minor changes in the XML configuration format for release 5.0.2. Before the migration, the following is displayed:

Preparing to migrate 5.0/5.0.1 configuration...

Please carefully note any instructions given during the migration since some configuration options have changed in this release.

After the migration, the following is displayed:

Successfully migrated

/opt/CSCOnfc/config/nfc-config.xml.

Please carefully note

any instructions above regarding additional

configuration updates

that might be needed.

In certain unusual cases, this can be preceded by additional information about a configuration incompatibility that cannot be resolved automatically. In that case, refer to details about configuration format updates introduced in CNS Netflow Collection Engine, Release 5.0.2 in the Release Notes for Cisco CNS NetFlow Collection Engine, 5.0.2.

Step 10 Ownership of all files under the install directory /opt/CSCOnfc is set to the user that was specified earlier; group ownership is set to that user’s default group.

Setting file ownership...

Next, operating system-specific configuration is verified:

Checking platform config...

This includes verifying that the data segment size limit returned by ulimit –dis sufficient. If not, a warning message is displayed, and you should consult the platform system administration guide to determine how this value is updated. This value should be at least the maximum size specified for the collector process as described at [link to memory tuning section of customizing chapter].
