First-Time Startup

• Power up your router and if necessary, test for problems with system memory and CPU.
  
  
• Verify software version and installed hardware and software options.
  
  
• Configure global parameters.
  
  
• Configure interface parameters.
  
  
• Store the configuration in nonvolatile memory.
  
  

Additionally, if you enter invalid information at a prompt, the help facility automatically asks you for the correct information. For example, if you answer "okay" instead of "yes" at a prompt, the help facility guides you with the following information:

As another example, if you answer a prompt with a value of 0 and the required value must be a decimal between 1 and 65535, then the help facility automatically prompts you with the following message:

Caution Check the voltage rating label at the back of the unit for correct voltage configuration. The factory configures the AGS+ for either 110 VAC or 220 VAC operation, as requested when ordered. MGS, CGS, Cisco 3000, and Cisco 7000 products automatically configure the power supply for the applied input voltage and can be connected to any AC source from 90 to 264 VAC. All U.K. version products are configured at the factory for 240 VAC operation only.

Now you can safely power up your system by flipping the switch on the back of the router.

The next portion of the script lists installed hardware and software options, such as bridging and X.25. The system presents the appropriate interfaces for these options during the configuration process.

The System Configuration Dialog appears, and asks whether you want to begin the configuration dialog.

At this point, you can choose to exit the System Configuration Dialog by answering No at the prompt. To begin the initial configuration process, answer Yes. If you answer Yes, the System Configuration Dialog asks whether you want to view the current interface summary. Answer Yes to see the summary.

In the following example, the summary shows a router at first-time startup. That is, nothing has been configured, and the summary reflects that fact.

The interface summary contains six columns. The Interface column lists the router's installed interfaces.The IP-Address column lists the IP address for each interface or states that an IP address for an interface is currently unassigned. Because this example shows the summary at first-time startup (that is, prior to configuration), no IP addresses have yet been assigned. The OK? column describes whether an interface has a valid configuration. Again, no configuration exists, so the OK? column contains NO for each interface. The Method column describes where an interface gets its configuration information—manually or from NVRAM. If you have not configured the interface with an IP address, the column shows "not set" for the interface. The Status column indicates whether an interface is up, down, or administratively down. Ethernet interfaces have a default status of up. Therefore, when you power up your router, Ethernet interfaces are usually up. Serial interfaces are not up unless they receive the correct carrier detect signal on the line.The Protocol column lists the line protocol for an interface. A line protocol tells you whether the interface line missed the last three keepalives. If so, the column shows "down" for that interface.

After displaying the interface summary, the dialog begins to prompt you for global configuration parameters. You can press Ctrl-C to abort the process at any time. Ctrl-C returns you to the privileged EXEC prompt (router#). Refer to the Router Products Configuration Guide for information about configuring the router. Refer to the publication Protocol Translation Configuration Guide and Command Reference for information about configuring protocol translation.

If a --More-- prompt appears during the dialog, press the space bar to continue.

Once you have answered Yes to this last question, your system is now ready for use. If you want to modify the configuration you have just established, see the "Where to Go from Here" chapter.

In the sample System Configuration Dialog, when it appears that no response was made, the user pressed the Return key to accept the default.
