Saving and Retrieving the Conﬁguration File

Installation Prerequisites

Flash Memory Card Replacement and Formatting Prerequisites

If you have a Flash memory card installed in the PCMCIA slot of your RP, you must reformat it if you want to use it with your new RSP7000. Using the RSP7000, you cannot read data on the RP’s Flash memory card, nor can you use it as bootable media. You must reformat the RP’s Flash card on the RSP7000 before you can use it with the RSP7000. Flash memory cards formatted on the RP-based systems (7000 series routers) are formatted differently from Flash memory cards formatted on RSP-based systems (7500 series routers or 7000 series routers equipped with an RSP7000).

Caution The formatting procedure erases all information on the Flash memory card. To prevent the loss of important data that might be stored on a Flash memory card, proceed carefully. If you want to save the data on a Flash memory card, copy the data to a server before you format the card.

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-conﬁgstartup-conﬁgcommand 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-conﬁgstartup-conﬁgcommand 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.
