Verify the Network Port Configuration

After you install CentOS and log in as root, the nba-package-installer script automatically configures all standard network ports for DHCP operation and enables these ports. To prevent reconfiguration of these ports on future root logins, the script creates a lock file.

To verify the network port configuration:

Verify that the port that you have connected for management use has been allocated an IP address. If the address allocation succeeds, the script displays a message like the following:
```
Bringing up interface ethX:
Determining IP information for ethX... done.
                                                         [ OK ]
```
Verify that IP addresses have been allocated to the other network ports. The success or failure to allocate an IP address depends on the wiring and network configuration.
For example, if the script fails to allocate an IP address to ports that are not wired to a network, the script displays messages like the following:
```
Bringing up interface ethX:
Determining IP information for ethX... failed; no link present.  Check cable?
                                                          [FAILED]
```
In these examples, ethX indicates the Ethernet port where X represents the port number, such as eth1.
Investigate the port configuration and cabling for those ports where success or failure is not as expected (see "Troubleshooting" for more information).
When the network port configuration is complete, the following message displays:
```
Creating lock file to prevent repeated network port reconfiguration.
Network ports configuration OK
```
The script creates the file /opt/ca/ca-dlp/nba/lock/nba-package-installer-network.lock.

Now the installer prompts you to install the Napatech driver. Continue with the next section.
