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. |
The chapter includes the following sections:
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.
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. |
To configure a static IP route, perform the following steps, beginning in global configuration mode:
| Command | Purpose | |
|---|---|---|
Step 1 | Switch(config)# ip route prefix1 mask2 ethernet 0 | atm 0[.subinterface#] | Configures a static IP route on the Ethernet interface or ATM subinterface of the route processor. |
Step 2 | Switch(config)# end Switch# | Returns to privileged EXEC mode. |
Step 3 | Switch# copy system:running-config nvram:startup-config | Saves the configuration to NVRAM. |
| 1The IP route prefix of the remote network where the management station or TFTP server resides. 2The subnet mask of the remote network where the management station or TFTP server resides. |
Switch(config)# interface ethernet 0 Switch(config-if)# ip address 172.20.52.11 255.255.255.224 Switch(config-if)# end Switch# copy system:running-config nvram:startup-config
This release of the ATM switch router system software uses the Cisco IFS (IOS File System). With IFS, you now access files on a storage device by specifying a filename and the file system containing the file. The following old command, for example, accesses the running-config and startup-config files:
Switch# copy running-config startup-config
With IFS, you additionally specify the system containing the files using the syntax filesystem:filename. For example:
Switch# copy system:running-config nvram:startup-config
The syntax filesystem:filename is called the file URL. In addition, remote file systems (such as TFTP, FTP, and rcp) allow you to specify additional options in the file URL, such as username, password, remote host, and so on. This way, you can enter all the required information at once without having to respond to prompts.
With IFS, some show commands have been replaced with more commands. For example:
Switch# show running-config
has been replaced with the following command:
Switch# more system:running-config
For complete information on using file URLs and the new IFS commands and syntax, refer to the Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command Reference publications.
File systems on the ATM switch router include read-only memory (RAM, or system), Flash memory (such as bootflash and the Flash PC cards in slot0 and slot1), and remote file systems (such as TFTP or rcp servers).
You can use the show file systems privileged EXEC command to display the valid file systems on your ATM switch router. The following example shows the file systems on a Catalyst 8540 MSR:
Switch# show file systems

You can load functional images used by certain hardware controllers in the ATM switch router. This section describes the function and maintenance of functional image.
Functional images provide the low-level operating functionality for various hardware controllers. On hardware controllers with insystem programmable devices, such as field programmable gate arrays (FPGAs) and Erasable Programmable Logic Devices (EPLDs), the hardware functional images can be reprogrammed independently of loading the system image and without removing the devices from the controller.
On the ATM switch router, you can reprogram the functional images on the route processors, rommon, switch processors, switch processor feature cards, carrier modules, full-width modules, and network clock modules.
All new hardware is shipped with functional images preloaded. Loading a different functional image is required only when upgrading or downgrading functional image versions.
You load a functional image in two steps:
Step 2 Load the image from the Flash memory device to the hardware controller.
|
Note The command for loading functional images on the ATM switch router differs from that described in the Cisco IOS documentation. |
To download a functional image from a Flash memory device to a hardware controller, use the following command in privileged EXEC mode:
Command | Purpose |
|---|---|
|
|
The reprogram command checks the compatibility of the image for the selected card type before downloading the functional image. If you have specified a slot number without a subcard, the functional image is downloaded to the full-width module that occupies that slot.
|
Note After loading a new functional image on the primary route processor or on one of the switch processors, you must power-cycle the switch for the hardware to reconfigure itself with the new image. |
|
Caution Do not interrupt the download procedure. Wait until it has finished before attempting any commands on the switch. |
The following example demonstrates loading the functional image fi_c8540_rp.B.3_91 from the Flash PC card in slot 0 to the controller for the route processor in slot 4.
Switch# reprogram slot0:fi_c8540_rp.B.3_91 4
To display the functional image version in a hardware controller, use the following command in privileged EXEC mode:
Command | Purpose |

The following example shows the functional image information in the controller for the route processor module in slot 4:
