The "First-Time Startup" chapter described how to get your router started for the first time using the setup command facility. This chapter describes the following tasks:
For information about using the EXEC command interpreter, refer to the Router Products Configuration Guide. For information about specific commands, refer to the Router Products Command Reference publication. For information about configuring protocol translation, refer to the publication Protocol Translator Configuration Guide and Command Reference.
You can use the setup command facility after first-time startup to make basic changes at any time. The changes you make affect only the changed elements in current running memory and in nonvolatile memory (NVRAM).
When you enter the setup command facility after first-time startup, you must run through the entire dialog until you come to the element you intend to change. In the System Configuration Dialog, the default values indicated in brackets are the values last set using the setup command facility. They were accepted as defaults, or were supplied using the configure command.
If you decide not to make the change while in the System Configuration Dialog, press Ctrl-C to return to the privileged EXEC prompt.
Refer to the "Preparing for First-Time Startup" chapter for complete descriptions of the values you can assign to each item.
The streamlined setup command facility permits your router to netboot an image even though there could be problems with the configuration in NVRAM. The streamlined setup command facility is available only if your router is running from ROM monitor and it has RXBOOT ROMs installed. The following routers can have this type of ROM installed:
The streamlined setup command facility is different from the standard setup command facility in that the streamlined facility does not ask you to configure global router parameters. You are prompted only to configure interface parameters, which permit your router to boot.
The router enters the streamlined setup command facility if, after any of the following circumstances occurs, your router is accidentally or intentionally rebooted (or you are attempting to netboot):
The following example shows a router entering the streamlined setup command facility because the router is being netbooted and it does not have a valid image in NVRAM:
--- System Configuration Dialog ---
Refer to the 'Getting Started' Guide for additional help.
Default settings are in square brackets '[]'.
Configuring interface IP parameters for netbooting:
Configuring interface Ethernet0:
Is this interface in use? [yes]:
Configure IP on this interface? [yes]:
IP address for this interface: 192.195.78.50
Number of bits in subnet field [0]: 5
Class C network is 192.195.78.0, 5 subnet bits; mask is 255.255.255.248
Configuring interface Serial0:
Is this interface in use? [yes]:
Configure IP on this interface? [yes]:
IP address for this interface: 192.195.78.34
Number of bits in subnet field [5]:
Class C network is 192.195.78.0, 5 subnet bits; mask is 255.255.255.248
The system then displays the command script that was created as a result of your configuring the router through the streamlined setup command facility.
You are asked to provide an IP address and subnet mask bits. Enter the subnet mask bits as a decimal value, such as 8.
The configuration information you provide on this screen is temporary and exists only so that you can proceed with booting your system. When you reload the system, your original configuration is left intact. If your image in NVRAM is corrupted, enter the setup command facility, and configure the basic parameters. Then issue the write memory command to write this configuration to NVRAM. Refer to the Router Products Configuration Guide for further details.
You can review the changes you made to the configuration. To display information stored in NVRAM, use the EXEC command show configuration.
After you have established the basic startup configuration for your router, refer to the Router Products Configuration Guide or the Router Products Command Reference publication for information on using the configure command to make advanced configuration changes.
The configuration guide also provides information about the following tasks:
To configure your router for protocol translation, refer to the publication Protocol Translator Configuration Guide and Command Reference.
