Information About the Cisco NX-OS Setup Utility
The Cisco NX-OS setup utility is an interactive command-line interface (CLI) mode that guides you through a basic (also called a startup) configuration of the system. The setup utility allows you to configure only enough connectivity for system management.
The setup utility allows you to build an initial configuration file using the System Configuration Dialog. The setup starts automatically when a device has no configuration file in NVRAM. The dialog guides you through initial configuration.After the file is created, you can use the CLI to perform additional configuration.
You can press Ctrl-C at any prompt to skip the remaining configuration options and proceed with what you have configured up to that point, except for the administrator password. If you want to skip answers to any questions, press Enter. If a default answer is not available (for example, an IP address), the setup utility uses what was previously configured and skips to the next question. Figure 2-1 shows how to enter and exit the setup script.
Figure 2-1 Setup Script Flow
You use the setup utility mainly for configuring the system initially, when no configuration is present. However, you can also use the setup utility at any time for basic device configuration by entering the setup command at the CLI in any command mode. The setup utility keeps the configured values when you skip steps in the script. For example, if you have already configured the mgmt0 interface, the setup utility does not change that configuration if you skip that step. However, if there is a default value for the step, the setup utility changes to configuration using that default, not the configured value. Be sure to carefully check the configuration changes before you save the configuration.
Note Be sure to configure the IPv4 route, the default network IPv4 address, and the default gateway IPv4 address to enable SNMP access. If you enable IPv4 routing, the device uses the IPv4 route and the default network IPv4 address. If IPv4 routing is disabled, the device uses the default gateway IPv4 address.
The setup script only supports IPv4. For information on configuring IPv6, see the Cisco Nexus 7000 Series NX-OS Unicast Routing Configuration Guide, Release 4.0.
Prerequisites for the Setup Utility
The setup utility has the following prerequisites:
•Have a password strategy for your network environment.
•Connect the console port on the supervisor module to the network. If you have dual supervisor modules, connect the console ports on both supervisor modules to the network.
•Connect the Ethernet management port on the supervisor module to the network. If you have dual supervisor modules, connect the Ethernet management ports on both supervisor modules to the network.
Setting Up Your Cisco NX-OS Device
To configure basic management of the Cisco NX-OS device using the setup utility, follow these steps:
Step 1 Power on the device.
Step 2 Enter the new password for the administrator.
Tip If a password is trivial (such as a short, easy-to-decipher password), your password configuration is rejected. Passwords are case-sensitive. Be sure to configure a strong password that are at least eight characters long, contain both upper- and lower-case letters, and contain numbers.
Enter the password for "admin": <password>
Confirm the password for "admin": <password>
---- Basic System Configuration Dialog VDC: 1 ----
This setup utility will guide you through the basic configuration of the system. Setup
configures only enough connectivity for management of the system.
Please register Cisco Nexus7000 Family devices promptly with your supplier. Failure to
register may affect response times for initial service calls. Nexus7000 devices must be
registered to receive entitled support services.
Press Enter at anytime to skip a dialog. Use ctrl-c at anytime to skip the remaining
dialogs.

Would you like to edit the configuration? (yes/no) [n]: no
Step 24 Use and save this configuration by entering yes.
Use this configuration and save it? (yes/no) [y]: yes
Caution
If you do not save the configuration at this point, none of your changes are part of the configuration the next time the device reboots. Type
yes to save the new configuration. This ensures that the boot variables for the kickstart and system images are also automatically configured.
Note You can reenter the setup utility at any time using the setup command in any command mode.
