Remember how to install a permanent and Right-To-Use license. To install a permanent license on a
router, use the
install license
url
command. To install an evaluation feature, use the
license boot
module
command.
Remember the verification commands used for licensing in the new ISR G2 routers. The
show
license
command determines the licenses that are active on your system. The
show
license feature
command allows you to view the technology package licenses and feature licenses that are supported on your
router. The
show license udi
command displays the unique device identifier (UDI) of the router, which
comprises the product ID (PID) and serial number of the router, and the
show version
command displays
information about the current IOS version, including the licensing details at the end of the command’s output.
Written Lab 8 You can find the answers to this labs in Appendix A, “Answers to Written Labs.”
In this section, you’ll complete the following lab to make sure you’ve got the information and concepts contained
within them fully dialed in:
1. Lab 8.1: IOS Management
Written Lab 8.1: IOS Management Write the answers to the following questions:
1. What is the command to copy a Cisco IOS to a TFTP server?
2. What do you set the configuration register setting to in order to boot the mini-IOS in ROM?
3. What is the configuration register setting to tell the router to look in NVRAM for the boot sequence?
4. What do you set the configuration register setting to in order to boot to ROM monitor mode?
5. What is used with a PAK to generate a license file?
6. What is the configuration register setting for password recovery?
7. Which command can change the location from which the system loads the IOS?
8. What is the first step of the router boot sequence?
9. What command can you use to upgrade a Cisco IOS?
10. Which command determines the licenses that are active on your system?
Hands-on Labs To complete the labs in this section, you need at least one router (three would be best) and at least one PC running
as a TFTP server. TFTP server software must be installed and running on the PC. For these labs, it is also assumed
that your PC and the router(s) are connected together with a switch or hub and that all interfaces (PC NIC and
router interfaces) are in the same subnet. You can alternately connect the PC directly to the router or connect the
routers directly to one another (use a crossover cable in that case). Remember that the labs listed here were
created for use with real routers but can easily be used with the LammleSim IOS version (found at
www.lammle.com/ccna
) or Cisco’s Packet Tracer program.
Here is a list of the labs in this chapter:
1. Lab 8.1: Backing Up Your Router IOS
2. Lab 8.2: Upgrading or Restoring Your Router IOS
