Cisco Router and Security Device Manager
If the Cisco Router and Security Device Manager (SDM) has been installed on your router, the following
messages appear at the end of the startup sequence:

Press RETURN to get started.
For instructions on configuring your router by using SDM, see the Cisco Router and Security Device
Manager (SDM) Quick Start Guide. To use SDM, you can download the latest version of SDM and
instructions for installing it on your router:

To obtain the SDM quick start guide, SDM release notes, and other SDM documentation, go to
www.cisco.com/go/sdm.
Verifying the Initial Configuration
Verify that the new interfaces are operating correctly by performing the following tests:
• Enter the show interfaces command to verify that the interfaces are operating correctly and that the
interfaces and line protocol are in the correct state—up or down.
• Enter the show ip interface brief command to display a summary status of the interfaces configured
for IP.
• Enter the show configuration command to verify that you configured the correct hostname and
password.
When you have completed and verified the initial configuration, your Cisco router is ready to be
configured for specific functions. See the “Completing the Configuration” section on page 7-6 for
information about locating documentation for advanced configuration procedures.
