Upgrading Your CSS Software
Cisco Systems periodically releases new software versions for the CSS. To help
you upgrade your CSS with a new software release, this appendix provides the
following information:
•

•
Before You Begin
Upgrading Your CSS
Updating Management Information Base Files (MIBs)
Note
When Cisco Systems makes syntax changes to existing CLI commands, the CSS
updates your startup-config automatically with most command syntax changes.
For example, the CSS automatically updates the web-mgmt state enabled
command in the startup config to the new no restrict web-mgmt command. If the
CSS does not update a command syntax change in a startup-config automatically,
a startup error is displayed. Refer to the Release Note for the Cisco Series Content
Services Switch for information on which command syntax changes display
startup-config errors.

Appendix A Upgrading Your CSS Software
Upgrading Your CSS
Using the Upgrade Script
The upgrade script allows you to upgrade your CSS without having to enter any
CLI commands. There are two ways to run the script:
•
•
Automatically Running the Upgrade Script
Interactively Using the Upgrade Script
Note
If the upgrade script fails while upgrading the CSS to the same version of software
that is currently running, the CSS software directory will be incomplete. To
reinstall the software, you must upgrade the CSS manually (that is, FTP the .adi
file to the CSS and perform a manual unpack).
Automatically Running the Upgrade Script
You can run the upgrade script to perform the software upgrade without having to
enter any information. The script automatically:
•
Checks to see how many installed software versions are installed on the CSS.
If there are two installed versions (the maximum), the script deletes an older
version.
Note
The script will not offer to delete a version that you have configured
as the primary or secondary boot file. On a flash disk-based system,
you may need to quit and then deselect the primary or secondary boot
file before continuing with the upgrade.
•
•
•
•
•
Archives the running configuration to the startup configuration.
Copies the new ADI to the CSS boot-image directory.
Unpacks the new ADI.
Sets the primary boot-file to the new ADI.
Reboots the CSS.

Appendix A Upgrading Your CSS Software
Upgrading Your CSS
To upgrade your CSS software using the upgrade script:
1. Log into the CSS.
2. Archive your custom scripts and user-profile files from the CSS scripts
directory to the archive directory. The upgrade overwrites files in the script
directory but does not overwrite files in the archive directory. After the
upgrade, you will restore these files to the scripts directory.
To archive each file to the archive directory, use the archive script command.
The syntax for this command is:
archive script script_filename {archive_filename}
The variables are as follows:
•
script_filename - The filename of the script to archive. To see a list of
scripts, enter:
# archive script ?
•
archive_filename - (Optional) The name you want to assign to the archive
file. Enter an unquoted text string with a maximum of 32 characters.
For example, to archive the admin-profile file from the scripts directory to the
archive directory, enter:
# archive script admin-profile
To copy any changes to your current user profile to the script directory and
then archive the profile to the archive directory, use the alias save_profile
command. For example, enter:
# save_profile
3. Start the upgrade script and include the name of the ADI and its extension in
quotes.
•
If you are using a GZIP-compressed ADI from the FTP server, include
the gz file extension. For example:
# upgrade “sg0710002.adi.gz”
•
If you are using an uncompressed version of the ADI from the FTP
server, include the adi file extension. For example:
# upgrade “sg0710002.adi”
Cisco Content Services Switch Adminisitration Guide
78-13885-03

Appendix A Upgrading Your CSS Software
Upgrading Your CSS
If you did not configure a default FTP record before starting the upgrade
script, the script prompts you to configure one. You can either:
•
Allow the CSS to automatically configure a record to the server
containing the ADI.
•
At the prompts, manually configure the FTP record by entering the FTP
server information where you copied the upgrade ADI.
When a default FTP record is configured, information similar to the following
appears during the upgrade:
Current Version:sg0710002 (Build 2)
*** You must remove an installed version to upgrade. ***
Attempting to delete sg0710001

Completed successfully.
#(config-boot)#
unpack ${new_version_adi}
Unpacking(/) 99%
(config-boot)#
setting primary boot-file sg0710002
rebooting
The CSS automatically performs a flash upgrade, if necessary, and then boots
the new image.
4. After you upgrade the software in a CSS 11506 that contains a passive SCM,
use the passive sync command in boot-config mode (or the passive sync
macro command) immediately after upgrading your CSS software to
synchronize the boot configurations on the redundant SCMs. Refer to
Chapter 1, Logging In and Getting Started, the “Configuring a Boot
Configuration Record for the Passive SCM” section.
5. Use the restore command to restore the startup-config file, custom scripts,
and user-profile files previously archived in the CSS archive directory. To see
a list of files in the archive directory, enter:
# restore ?

•
•
To restore the startup-config file, use the restore filename startup-config
command. For example, to restore the startup-config file in the archive
directory as the startup-config file on the CSS, enter:
# restore startup-config startup-config
To restore each custom script and user profile file to the script directory,
use the restore filename script command. For example, to restore the
admin-profile filename to the CSS script directory, enter:
# restore admin-profile script
Interactively Using the Upgrade Script
The upgrade script allows you to enter information and make selections by
responding to prompts as it runs. Before the script performs the upgrade, it
prompts you to:
•
Remove ADIs from the CSS if the script detects two installed versions on a
hard disk-based system or on a flash disk-based system
•
•
•
•
Enter the version of the new ADI
Set the primary boot-file to the new ADI
Reboot the CSS with the ADI you are installing after the upgrade is done
Archive the running configuration to the startup configuration
To use the interactive version of the script:
1. Log into the CSS.
2. Archive your custom scripts and user-profile files from the CSS scripts
directory to the archive directory. The upgrade overwrites files in the script
directory but does not overwrite files in the archive directory. After the
upgrade, you will restore these files to the scripts directory.
To archive each file to the archive directory, use the archive script command.
The syntax for this command is:
archive script script_filename {archive_filename}

The variables are as follows:
•
script_filename - The filename of the script to archive. To see a list of
scripts, enter:
# archive script ?
•
archive_filename - (Optional) The name you want to assign to the archive
file. Enter an unquoted text string with a maximum of 32 characters.
For example, to archive the admin-profile file from the scripts directory to the
archive directory, enter:
# archive script admin-profile
To copy any changes to your current user profile to the script directory and
then archive the profile to the archive directory, use the alias save_profile
command. For example, enter:
# save_profile
3. Start the upgrade script. For example:
# upgrade
If you did not configure a default FTP record before starting the upgrade
script, the script prompts you to configure one. You can either:
•
Allow the CSS to automatically configure a record to the server
containing the ADI.
•
At the prompts, manually configure the FTP record by entering the FTP
server information where you copied the upgrade ADI.
When a default FTP record is configured, the script displays the current
version of the ADI.
Current Version: sg0710002 (Official)
If the script detects the maximum number of ADIs (two), a message informs
you that you need to remove an ADI. Then the script prompts you to remove
an older ADI. For example:
*** You must remove an installed version to upgrade.***
remove sg0710001[y n q]?

Note
The script will not offer to delete a version that you have configured
as the primary or secondary boot file. On a flash disk-based system,
you may need to quit and then deselect the primary or secondary boot
file before continuing with the upgrade.
4. If necessary, remove the ADI.
•
•
•
Enter y to remove the displayed ADI version.
Enter n for the script to display another version to remove.
Enter q to exit from the script.

5. At the prompt, enter the file name and extension of the GZIP-compressed
ADI version to install, and verify the information you entered. For example:
Please Enter Version to Install:sg0710002.adi.gz
Note
If you are using an uncompressed version of the ADI from the FTP server,
include the adi file extension (for example, sg0710002.adi).
Upgrade to Version sg0710002? [y n q] y
6. Determine whether to set the ADI as the primary boot-file.
•
Enter y to set the ADI as the primary boot-file and change the CSS
configuration.
•
Enter n to keep the same primary boot-file configuration.
Set primary boot-file to Version sg0710002? [y n q] y
7. Determine whether to have the CSS reboot with the ADI you are installing.
•
•
Enter y to reboot the CSS with this ADI after the upgrade is done.
Enter n to not reboot the CSS with the ADI after the upgrade is done.
Reboot with Version sg0710002? [y n q] n

8. Determine whether to have the CSS archive the contents of the
running-config file to the startup-config file.
•
Enter y to archive the contents of the running-config file to the
startup-config file.
•
Enter n to keep the same startup configuration.
Archive running-config to startup-config? [y n q] y
archive running-config startup-config
The script copies the ADI from the FTP server, unpacks and installs it, and
sets it as the primary boot-file.
Attempting ftp of sg0710002.adi.gz:
#
copy ftp DEFAULT_FTP ${new_version_adi} boot-image
Copying (-) 57,241,012
Completed successfully.
#
(config-boot)# unpack ${new_version_adi}
unpacking(/) 99%
(config-boot)#
setting primary boot-file sg0710002
9. If you decided to reboot the CSS with the installed ADI in Step 7, the CSS
reboots automatically. If you made the ADI the primary boot-file and
archived the contents of the running-config file to the startup-config file, the
CSS automatically performs a flash upgrade, if necessary, and then boots the
new image.
To manually reboot the system, enter the following commands:
(config)# boot
(config-boot)# reboot
10. After you upgrade the software in a CSS 11506 that contains a passive SCM,
use the passive sync command in boot-config mode (or the passive sync
macro command) immediately after upgrading your CSS software to
synchronize the boot configurations on the redundant SCMs. Refer to
Chapter 1, Logging In and Getting Started, the “Configuring a Boot
Configuration Record for the Passive SCM” section.

11. Use the restore command to restore the startup-config file, custom scripts,
and user-profile files previously archived in the CSS archive directory. To see
a list of files in the archive directory, enter:
# restore ?
•
To restore the startup-config file, use the restore filename startup-config
command. For example, to restore the startup-config file in the archive
directory as the startup-config file on the CSS, enter:
# restore startup-config startup-config
•
To restore each custom script and user profile file to the script directory,
use the restore filename script command. For example, to restore the
admin-profile filename to the CSS script directory, enter:
# restore admin-profile script
Manually Upgrading the CSS
You can manually enter CLI commands to upgrade the CSS.
Note
Make sure that you configure a default FTP server, as described in the “Before
You Begin” section earlier in this appendix.
To manually upgrade the software version on your CSS:
1. Log onto the CSS.
2. If there are two installed versions (the maximum), remove an older version of
the ADI from the CSS.
Caution
Do not remove the ADI currently running on the CSS. Use the version command
to see the currently running software version.
Cisco Content Services Switch Adminisitration Guide

Appendix A Upgrading Your CSS Software
Upgrading Your CSS
To remove an ADI:
a. List the ADIs on the CSS. For example:
(config)# show installed-software
sg0710001
sg0710002
b. Access boot mode:
(config)# boot
(config-boot)#
c. Use the remove command to remove the ADI. For example:
(config-boot)# remove sg0710001
3. Archive your running configuration to the startup configuration. For example:
# config
(config)# archive running-config startup-config
You can also use the save_config alias to archive your startup-config file. To
view all available aliases, use the show aliases command.
Note
If you created additional profiles on the CSS, archive them by using
the archive script or save_profile command. After the upgrade is
done, use the restore filename script command to restore the profile
you archived.
4. Archive your custom scripts and user-profile files from the CSS scripts
directory to the archive directory. The upgrade overwrites files in the script
directory but does not overwrite files in the archive directory. After the
upgrade, you will restore these files to the scripts directory.
To archive each file to the archive directory, use the archive script command.
The syntax for this command is:
archive script script_filename {archive_filename}

The variables are as follows:
•
script_filename - The filename of the script to archive. To see a list of
scripts, enter:
# archive script ?
•
archive_filename - (Optional) The name you want to assign to the archive
file. Enter an unquoted text string with a maximum of 32 characters.
For example, to archive the admin-profile file from the scripts directory to the
archive directory, enter:
# archive script admin-profile
To copy any changes to your current user profile to the script directory and
then archive the profile to the archive directory, use the alias save_profile
command. For example, enter:
# save_profile
5. Copy the new ADI to the CSS as the boot-image.
(config-boot)# <Ctl-z>
# copy ftp DEFAULT_FTP sg0710002.adi.gz boot-image
DEFAULT_FTP is the FTP record file defined in “Configuring an FTP Server
Record on the CSS” earlier in this appendix.
When you copy a GZIP-compressed ADI onto the CSS, the CSS
automatically uncompresses it.
Note
If you are copying an uncompressed version of the ADI from the FTP
server, include the adi file extension (for example, sg0710002.adi).
6. Unpack the ADI. For example:
(config)# boot
(config-boot)# unpack sg0710002.adi
7. Set the new ADI as the primary boot-file and install it. For example:
(config-boot)# primary boot-file sg0710002
