Managing Configuration Files, System Images,
and Functional Images
This chapter describes some fundamental tasks you perform to maintain the configuration files, system
images, and hardware functional images used by your ATM switch router.
Note This chapter provides advanced configuration instructions for the Catalyst 8540 MSR,
Catalyst 8510 MSR, and LightStream 1010 ATM switch routers. For complete descriptions of the
commands mentioned in this chapter, refer to the ATM Switch Router Command Reference publication.
This chapter includes the following sections:
• Configuring a Static IP Route, page 26-1
• Understanding the Cisco IOS File System, page 26-2
• Maintaining System Images and Configuration Files, page 26-3
• Maintaining Functional Images (Catalyst 8540 MSR), page 26-5
• Maintaining Functional Images (Catalyst 8510 MSR and LightStream 1010), page 26-7
Check the information in the first sections of the chapter to determine if it applies to your installation.
Also, familiarize yourself with the Cisco IOS File System section, as this describes new features in this
release. If you are an experienced IOS user, you can skip the third section.
Configuring a Static IP Route
If you are managing the ATM switch router through an Ethernet interface or ATM subinterface on the
multiservice route processor, and your management station or Trivial File Transfer Protocol (TFTP)
server is on a different subnet than the ATM switch router, you must first configure a static IP route.
Caution Failure to configure a static IP route prior to installing the new image will result in a loss of remote
administrative access to the ATM switch router. If this happens, you can regain access from a direct
console connection, although this requires physical access to the console port.
