Saving and Retrieving the Conﬁguration File

This section describes the procedures for saving and retrieving the system conﬁguration.

Conﬁguration information resides in two places when the router is operating: the default

(permanent) conﬁguration in NVRAM, and the running (temporary) memory in RAM. The default

conﬁguration always remains available; NVRAM retains the information even when the power is

shut down. The current information is lost when if the system power is shut down. The current

conﬁguration contains all nondefault conﬁguration information that you added with the conﬁgure

command, the setup command facility, or by editing the conﬁguration ﬁle.

The copy running-conﬁg startup-conﬁg command adds the current conﬁguration to the default

conﬁguration in NVRAM, so that it will also be saved when power is shut down. Whenever you

make changes to the system conﬁguration, issue the copy running-conﬁg startup-conﬁg command

to ensure that the new conﬁguration is saved.

If you replace the RSP7000, you will also replace the entire conﬁguration (NVRAM resides in

socket U17 on the RSP7000). If you upload (copy) the conﬁguration ﬁle to a remote server before

removing the RSP7000, you can retrieve it later and write it into NVRAM on the new RSP7000. If

you do not upload the conﬁguration ﬁle, you will have to use the conﬁgure command or the setup

command facility to reenter the conﬁguration information after you install the new RSP7000. For

complete descriptions of these commands and instructions for using them, refer to the appropriate

software documentation.

This procedure is not necessary if you are temporarily removing an RSP7000 that you will reinstall;

the lithium batteries will retain the conﬁguration in memory until you replace the RSP7000 in the

system.

This procedure requires privileged-level access to the EXEC command interpreter, which usually

requires a password. Refer to the description that follows and contact your system administrator if

necessary, to obtain access.

Using the EXEC Command Interpreter

Before you use the conﬁgure command, you must enter the privileged level of the EXEC command

interpreter with the enable command. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket

(>). At the console terminal, enter the privileged level as follows:

Step 1

Step 2

Step 3

The pound sign (#) at the system prompt indicates that you are at the privileged level of the EXEC

command interpreter; you can now execute the EXEC-level commands that are described in the

following sections.

At the user-level EXEC prompt (>), enter the enable command. The EXEC command

interpreter prompts you for a privileged-level password, as follows:

Router> enable

Password:

Enter the password (the password is case sensitive). For security purposes, the password is

not displayed.

When you enter the correct password, the system displays the privileged-level system

prompt (#) as follows:
