Command-Line Interface

[OK]

Erase of nvram: complete

Router#sh start

%% Non-volatile configuration memory is not present

Router#

If you reload the router after using the erase startup-config com-

mand, you'll be put into setup mode. You can press Ctrl

+C to exit setup

mode at any time.

At this point, you shouldn't use setup mode to configure your router.

Setup mode was designed to help people who do not know how to use the
Cash Line Interface, and this no longer applies to you!

Verifying Your Configuration

Obviously, show running-config would be the best way to verify your
configuration, and show startup-config would be the best way to verify
the configuration that'll be used the next time the router is reloaded--
right?

Well, once you take a look at the running-config, and if all appears well,

you can verify your configuration with utilities like Ping and Telnet. Ping is
Packet Internet Groper, a program that uses ICMP echo requests and replies.
(ICMP is discussed in Chapter 3.) Ping sends a packet to a remote host, and
if that host responds, you know that the host is alive. But you don't know if
it's alive and also well--just because you can ping an NT server does not
mean you can log in. Even so, Ping is an awesome starting point for trouble-
shooting an internetwork.

Did you know that you can ping with different protocols? You can, and

you can test this by typing ping ? at either the router user-mode or privileged
mode prompt:

Router#ping ?

WORD Ping destination address or hostname

appletalk Appletalk echo

decnet DECnet echo

ip IP echo

ipx Novell/IPX echo

srb srb echo
