Software Upgrade
With the Software Upgrade page, you can perform software
upgrades on all or selected cluster members.
Before performing the upgrade, you must:
Then you can upgrade
the software.
To download a new version of switch software and the Cisco
TFTP server application from CCO to your PC or UNIX station hard
disk:
- Login to CCO by following the instructions in the Release
Notes for the Catalyst 2900 Series XL and the Catalyst
3500 Series XL, Cisco IOS Release 11.2(8)SA6.
- Download the TFTP server application by following the
instructions in CCO.
Note: To ensure full technical support,
Cisco Systems recommends using the TFTP server
application (Version 1.1). Earlier versions of this
application will not properly copy the files during the
upgrade process.
- Download the tar file (combined IOS image and CVSM
software HTML) by following the instructions in CCO.
Note: The tar file contains the same
software as the corresponding .bin and HTML files.
For information about the image filenames, see the Release
Notes for the Catalyst 2900 Series XL and the Catalyst
3500 Series XL, Cisco IOS Release 11.2(8)SA6.
You need the IP address of the PC or UNIX station that is
acting as the TFTP server.
- To obtain the IP address of a Windows NT system, enter ipconfig
at the DOS command prompt.
- To obtain the IP address of a Windows 95 system, enter winipcfg
from the Windows Start > Run menu.
- To obtain the IP address of a UNIX station, enter ifconfig
-a at the prompt or look in the /etc/hosts file.
Note: You can also obtain the IP address of
your PC if it is running the Cisco TFTP server application. This
application displays the IP address of the TFTP server on the
title bar.
The following procedure shows you how to upgrade from
11.2(8)SA6 to 11.2(8)SA6 (for example, from standard to
Enterprise Edition Software) and from 11.2(8)SA6 to a later
version of software. To perform this procedure:
- In the TFTP Server IP Address field, enter the IP address
of your TFTP server.
Note: Your TFTP server must be capable
of handling multiple requests and sessions at the same
time in order to perform group upgrades. If you are using
Cisco's TFTP server application, which is capable of
handling multiple requests and session, you must disable
the Show File Transfer Progress and the Enable
Logging options to avoid TFTP server crashes. To
disable these options, select View > Options
from the Cisco TFTP server menu bar and deselect these
options.
- In the New IOS Image File Name field, enter the filename
of the tar file that you downloaded from CCO (such as
c2900XL-h2s-mz-112.8-SA6.tar or
c3500XL-c3h2s-mz-112.8-SA6.tar).
For information about the image filenames, see the Release
Notes for the Catalyst 2900 Series XL and the Catalyst
3500 Series XL, Cisco IOS Release 11.2(8)SA6.
Note: You can enter the path and
filename in this field; you can precede the path with a
single slash (/) or no slash. If you enter only the
filename in this field, you must set up the path in the
TFTP root directory of the TFTP server application.
- Select the Retain Current IOS Image File Names
checkbox if you want to keep your existing file name from
being replaced with the new IOS image file name.
By default, this checkbox is deselected, and the image
will be renamed with the new name.
- In the Available Cluster Members list box, select the
cluster member to be upgraded, and click Add>>.
Repeat this process until all members to be upgraded are
displayed in the Selected Cluster Members list box.
Note: You cannot upgrade 2900 XL and
3500 XL switches at the same time. You must separately
group and upgrade 2900 XL switches with 4 MB of DRAM
(model numbers WS-C2908-XL, WS-C2916M-XL, WS-C2924-XL,
and WS-2924C-XL) from other switches and only upgrade
them using the c2900XL-hs-mz-112.8-SA6.tar file.
You can remove switches from the Selected Cluster Members
list box by selecting the switch and clicking <<Remove.
- Click Upgrade to start the upgrade.
If Flash memory does not have enough space for two
images, the new image is copied over the existing one.
If Flash memory has enough space, the new image is copied
to the selected switches but does not replace the current
running image. Only after the new image is completely
downloaded is the old one erased. If you experience a
failure during the copy process, you can still reboot
your switch using the old image.
- Review the Software Upgrade Status Messages area to see
the history of the upgrade process.
The status messages tell you which devices successfully
upgraded and which ones failed.
- If you have more switches to upgrade, repeat Steps 2
through 6.
- Click Reboot Cluster to reboot all
switches in the cluster.
All configuration changes are automatically saved to
Flash memory. Then after a short delay, the new software
image is loaded and run after rebooting.
Note: You will lose connectivity to
Cluster Manager when you reboot the cluster.
