Cisco Internetwork Operating System

Setup Mode

You use the setup facility of Cisco IOS software to streamline the creation of conﬁguration

ﬁles. If Cisco IOS software determines that there is no conﬁguration ﬁle stored in NVRAM,

it will automatically enter setup mode when the access server boots. (See the section

“Conﬁguring the Access Server Manually Using the Setup Facility” in the chapter

“Conﬁguring the Cisco 2500 Series Access Server” for more information about the

setup command.)

Conﬁguration Files

You need to create and store a conﬁguration ﬁle in order to use the access server. The

conﬁguration ﬁle contains commands that enable protocol routing, assign addressing,

perform security, and so forth. Use the following privileged mode commands to work with

conﬁguration ﬁles on the access server:

• conﬁgure terminal—Modify the running conﬁguration manually from the terminal.

• show running-conﬁg (Cisco IOS Release 11.0 or later) or write terminal (earlier than

Cisco IOS Release 11.0)—Display the running conﬁguration.

• conﬁgure memory—Load the conﬁguration from NVRAM to RAM. This takes place

automatically when the system starts up.

• copy running-conﬁg startup-conﬁg (Cisco IOS Release 11.0 or later) or write

memory (earlier than Cisco IOS Release 11.0)—Copy the running conﬁguration in

RAM into the startup conﬁguration in NVRAM.

• copy tftp running-conﬁg (Cisco IOS Release 11.0 or later) or conﬁgure network

(earlier than Cisco IOS Release 11.0)—Load a conﬁguration ﬁle stored on a Trivial File

Transfer Protocol (TFTP) server into the running conﬁguration.

• copy running-conﬁg tftp (Cisco IOS Release 11.0 or later) or write network (earlier

than Cisco IOS Release 11.0)—Store the running conﬁguration on a TFTP server.

• show startup-conﬁg (Cisco IOS Release 11.0 or later) or show conﬁguration (earlier

than Cisco IOS Release 11.0)—Display the saved conﬁguration in NVRAM.

• erase startup-conﬁg (Cisco IOS Release 11.0 or later) or write erase (earlier than

Cisco IOS Release 11.0)—Erase the contents of NVRAM. If you enter the reload

command after the erase startup-conﬁg (or write erase) command, the access server

will not have a running conﬁguration.
