This chapter describes the tasks required for maintaining the Content Routing software:
Presently, two types of Content Routing software files are available on Cisco.com to download, files with the .pax suffix and files with the .bin suffix. The .pax file contains the full-image software and is the file routinely installed. The .bin file software is for recovery situations that require booting from the network, or restoring Flash memory. See the "Recovering the Software" section for instructions on loading your system image with the .bin file.
The following procedure describes how to upgrade the Content Router system software and optionally change the boot parameters.
Step 1 Download the .pax file to your Windows NT or UNIX machine.
Step 2 From the Windows NT or UNIX machine, use File Transfer Protocol (FTP) to put the new image file (for example, cr4430.pax) in the Content Router /local directory.
If you are using a command-line FTP client, perform the following substeps to put the .pax file on the Content Router. In the example, the Content Router IP address is 192.168.88.89:
a. At the command line of your Windows NT or UNIX host, enter:
ftp 192.168.88.89
b. Enter the Content Router user login and password when prompted.
c. The default FTP directory of the Content Router should be /local. Use the cd command as follows to make sure that you are in the /local directory of the Content Router:
cd /local
d. Set the FTP client to binary transfer mode:
bin
e. Put the .pax file on the Content Router. For example, if the upgrade software filename is cr4430.pax, enter:
put cr4430.pax
Step 3 Log on to the Content Router through the console port.
 |
Note Upgrading software can be done through Telnet, but the connection is broken when the Content Router reboots. |
Step 4 At the Content Router command prompt, enter install to install the image files. For example, if the filename is cr4430.pax, enter:
console# install cr4430.pax
Extracting .
Extracting ./imgname.txt
Extracting ./etc
Extracting ./etc/boot
... (etc)
Extracting ./[image_name].bin.dbg.cus1
File extraction done.
cr4430.pax: installation is complete.

You may type [reload] to reboot your box now
|
Note Be sure to copy the new image to Flash memory. The Content Router will not run the updated software version until the image is stored in memory and you reboot the system. If you choose not to copy the image to Flash memory when prompted, you can do so later by entering copy disk flash filename, where filename is the name of the image file (the .bin file extracted from the .pax file). |
Step 5 From the Content Router console, enter reload to reboot the Content Router:
console# reload

Press any key to stop auto-boot...
|
Note If you have not saved your most recent configuration to Flash memory (NVRAM), you will be asked to do so before rebooting the Content Router. |
If you want to stop the auto-boot process to change default boot parameters, perform the following steps (console connection only):
|
Note In the example, the Content Router boot device parameter is changed from net to flash. |
a. Press any key during the auto-boot sequence.
b. Enter c at the prompt to change the auto-boot settings.
c. At the boot device prompt, enter flash.
d. At the filename prompt, press Ctrl-D to quit the change-default-boot-parameter sequence.
e. At the console prompt, enter @.
Press any key to stop auto-boot...

System booted from "flash"
The Content Router can be booted from a system image resident on another network host (booted from the network) if the native onboard image is corrupted. A corrupted system image can result from a power failure that occurs while the installation procedure is updating the Flash memory. When the Content Router is booted from the network, a new Flash memory image can be installed.
Recovery software is available from Cisco.com. Make sure to download the correct .bin file for your model of Content Router.
To reboot the Content Router with recovery software, perform the following steps:
Step 1 Make sure you have a console connection established. Reboot your Content Router manually by toggling the power on/off switch.
Step 2 Stop the auto-boot process by pressing any key.
a. Enter c to change the auto-boot settings.
b. Enter net for the boot device type.
c. Enter the appropriate CCO filename, host IP address, IP network mask, server IP address, gateway IP address, protocol (FTP or Trivial File Transfer Protocol [TFTP]), username, and password. For example:

|
Note In case you need to boot from Flash memory again, use the copy command to put the image in Flash memory. |
The Content Routers are equipped with one or more disks that are properly partitioned at the factory before shipment.
The principal disk partition is the DOS file system (dosfs). The dosfs partition contains the image file and memory for system output from features such as syslog.
To verify that a disk is partitioned correctly, execute the show disk-partitions command. To display the volume names, execute the show disks command.
|
Note The UVFAT partition refers to the dosfs. |
Console# show disk-partitions /c0t0d0
Disk size : 17836667 sectors
Partition 1: CISCO_UVFAT_1, offset 63 sectors, size 3906250 sectors
Partition 4: UNUSED, offset 0 sectors, size 0 sectors
Console# show disk-partitions /c0t1d0
Disk size : 17836667 sectors
Partition 1: UNUSED, offset 0 sectors, size 0 sectors
Partition 4: UNUSED, offset 0 sectors, size 0 sectors
Console# show disks
/c0t0d0 (scsi bus 0, unit 0, lun 0)
/c0t1d0 (scsi bus 0, unit 1, lun 0)
|
Note The name of disk 0 is /c0t0d0; the name of disk 1 is /c0t1d0. The c indicates the SCSI controller number, t is the target number, and d is the logical unit number (LUN). |
At any time, you can use the show dosfs volumes command to verify volume status.
Console# show dosfs volumes
/c0t0d0s1: mounted
/c0t1d0s1: mounted
/local: mounted
|
Note You can substitute the alias /local for the dosfs volume name /c0t0d0. |
The dosfs partition may be unmounted if the dosfs unmount command was executed. If the dosfs partition is unmounted, mount the dosfs partition using the dosfs mount command.
If the dosfs mount command does not work properly, execute the show disk-partitions command. Check for the UVFAT partition. The size of the dosfs partition should be approximately 2 gigabytes. A sector is equal to 512 bytes. If there is no disk partition for the dosfs, see the next section "Repartitioning the Content Router Disks."
If the dosfs volume does not mount, perform the procedure in the "Checking and Repairing DOS File System Volumes" section. If the dosfs volume still does not mount after you perform this procedure, repartition and reformat the disks as described in the next section, "Repartitioning the Content Router Disks."
 |
Caution Anytime a volume is partitioned or formatted, all the data on the disk is lost. |
|
Caution Whenever a disk is partitioned, all the data on the disk is lost. |
To repartition disk 0, which is the location of the dosfs partition, enter the disk partition command.
|
Note The name of disk 0 is /c0t0d0. |
Console# disk partition /c0t0d0 dosfs
this will create a dos partition
total size of disk = 17836667
CISCO_UVFAT_1 vol /c0t0d0s1 part_off 63 part_siz 3906250
Following a repartition, you must format and mount the dosfs using the following commands:
If the first disk is reformatted, all the cache data is lost as well as all data in the dosfs partition. It will be necessary to reinstall the software image. See the "Recovering the Software" section.
|
Note If the dosfs partition is not mounted correctly, an error message may be generated from the CLI. An example of this error message follows. |
Console# cli command
Could not get stat information about /local <====
The dosfs partition may be corrupted if a power outage occurs while the Content Router is writing to the disk, or if the disk is removed while the Content Router is writing to the dosfs partitions.
If there is a problem caused by the corrupted dosfs FAT table, perform the following steps:
Step 1 Enter the dosfs check /local command.
Step 2 If an error message occurs, enter the dosfs unmount /local command.
Step 3 Enter the dosfs repair auto /local command.
Step 4 Enter the dosfs mount /local {rdonly | rdwr}command.
Step 5 If the dosfs mount fails after you enter the dosfs repair command, enter the dosfs format command followed by the dosfs mount command.
If you are working in the current working directory of /local, you may see the following error message:
Could not get stat information about /local.
You can enter the cd / command to avoid this error message.
|
Note Entering the dosfs check command effectively prevents system features (such as syslog or
transaction logging) from writing to the disk. Disregard error messages generated by these features
after entering the dosfs check command, as shown in the following example:tSyslog: Cannot write log to Disk File (/local/var/log/syslog.txt), OK
|
If a user password is forgotten, lost, or misconfigured, perform the following steps to reset the password.
|
Note There is no way to restore a lost password. You must reset the password to a new one, as described in this procedure. |
Step 1 Attach an ASCII terminal to the Content Router console port.
Step 2 Break to the bootstrap program prompt and press any key before the Content Router completes the auto-boot sequence.
a. Enter c to change the auto-boot settings.
b. Enter flash for the boot device type.
Press any key to stop auto-boot...

Step 3 Change the configuration flags field to 0x8000 (as shown above), and then enter @ to continue with the boot sequence.
|
Note Setting the configuration flag field to 0x8000 lets you enter the system, bypassing all security. Setting the configuration flag field to 0x4000 lets you bypass the NVRAM configuration. |
Step 4 Once you see the CLI prompt, set the password for the user using the user modify username name password new-password command in global configuration mode.
Step 5 Use the write command to save the configuration change.
By default, the Content Router has an admin user with no password set. When no password is set, you can enter anything as a password.
The following sample configurations are outputs of the show running-config command and can be used as a guide for configuring the Content Router. If a feature is not enabled, it does not appear in the running configuration display, though settings configured for that feature are displayed.
