Note
To avoid losing work you have completed, be sure to save your configuration occasionally as you
proceed. Use the copy
running-config startup-config command to save the configuration to
NVRAM.
Verifying the Initial Configuration
Enter the following commands in the Cisco IOS to verify the initial configuration on the router:
•
show version—Displays the system hardware version; the installed software version; the names and
sources of configuration files; the boot images; and the amount of installed DRAM, NVRAM, and
flash memory.
•
show diag—Lists and displays diagnostic information about the installed controllers, interface
processors, and port adapters.
•
show interfaces— Shows interfaces are operating correctly and that the interfaces and line protocol
are in the correct state—up or down
•
show ip interface brief— Displays a summary status of the interfaces configured for IP protocol.
•
show configuration— Verify that you have configured the correct hostname and password.
When you have completed and verified the initial configuration, the specific features and functions are
ready to be configured. See the Cisco
1900 Series, 2900 Series, and 3900 Series Software Configuration
Guide.
Note
If you need help with the interface and port numbering, see the “Slot, Port, and Interface Information”
section on page 1-27.
