This topic describes the screens used for system management.

Update Firmware (TFTP Server)
Can upgrade via HTTP or TFTP

© 2006 Cisco Systems, Inc. All rights reserved.

CWLF v1.0—m5-2

Select System Software > Software Upgrade. The currently loaded system software filename
and version (and bootloader version) are displayed.
The TFTP Upgrade window permits you to specify the TFTP file server to be used for
upgrading the access point software via TFTP. Enter either the IP address or the Domain Name
System (DNS) address of the TFTP server to be used.

To initiate the software upgrade, enter the file name (and directory, if necessary) in the Upgrade
System Software Tar File field and select the Upgrade radio button.
In addition, an HTTP upgrade of the system software can be initiated from the HTTP Upgrade
screen.
Note

5-112

HTTP is restricted to file sizes of 3 KB or less.

Upgrading System Image Files
archive download-sw
Use the archive download-sw command to download
a new image to the access point
Example—to download a new .tar file to the access
point:
BR1410#archive download-sw /overwrite /force-reload
tftp://223.255.254.253/tftpboot/navdeep/c1410-k9w7-tar

© 2006 Cisco Systems, Inc. All rights reserved.

CWLF v1.0—m5-3

archive download-sw
Use the archive download-sw privileged EXEC command on the access point to download a

new image from a TFTP server to the access point and to overwrite or keep the existing image.
archive download-sw {/force-reload | /imageonly | /leave-old-sw | /no-set-boot | /no-versioncheck | /destination-system stack-member-number | /only-system-type system-type | /overwrite |
/reload | /safe} source-url
See the following table for list of available parameters and syntax for the archive command.

5-113


Syntax Description
/force-reload

Unconditionally force a system reload after successfully downloading the
software image.

/imageonly

Download only the software image but not the HTML files associated with the
embedded device manager. The HTML files for the existing version are
deleted only if the existing version is being overwritten or removed.

/leave-old-sw

Keep the old software version after a successful download.

/no-set-boot

Do not alter the setting of the BOOT environment variable to point to the new
software image after it is successfully downloaded.

/no-versioncheck

Download the software image without checking the compatibility of the stack
protocol version on the image and on the switch stack.

/destinationsystem stackmembernumber

Specify the specific stack member to be upgraded. The range is 1 to 9.

/only-systemtype systemtype

Specify the specific system type to be upgraded. The range is 0 to FFFFFFFF.

/overwrite

Overwrite the software image in flash memory with the downloaded one.

/reload

Reload the system after successfully downloading the image unless the
configuration has been changed and not been saved.

/safe

Keep the current software image; do not delete it to make room for the new
software image before the new image is downloaded. The current image is
deleted after the download.

source-url

The source URL alias for a local or network file system. These options are
supported:
•
The syntax for the local flash file system on the standalone switch or the
stack master:
flash:
The syntax for the local flash file system on a stack member:
flash member number:
•
The syntax for the FTP:
ftp:[[//username[:password]@location]/directory]/image-name.tar
•
The syntax for an HTTP server:
http://[[username:password]@]{hostname | host-ip}[/directory]/image-name.tar
•
The syntax for a secure HTTP server:
https://[[username:password]@]{hostname | host-ip}[/directory]/imagename.tar
•
The syntax for the Remote Copy Protocol (RCP):
rcp:[[//username@location]/directory]/image-name.tar
•
The syntax for the TFTP:
tftp:[[//location]/directory]/image-name.tar
The image-name.tar is the software image to download and install on the
switch.

Configuration File Management

© 2006 Cisco Systems, Inc. All rights reserved.

CWLF v1.0—m5-4

From the System Software > System Configuration screen, the configuration (config.txt) file
used for the Cisco IOS access point may be archived to a local store or may be restored from a
locally stored file. In addition, you can select the Show tech support button to obtain technical
support information from the access point, and the access point can be returned to default
configuration parameters.
There are also diagnostic aid utilities available from this screen such as Restart Now and Blink
the access point LEDs.

Upgrading System Configuration Files
copy source-url destination-url
To copy any file from a source to a destination, use the copy

command in EXEC mode.
Example—to download a new configuration file to the Bridge:
R1410#copy tftp://223.255.254.253/tftpboot/n/new-config startup

To erase the configuration file and revert to the default settings
of the Bridge:
BR1410#write erase

Note: The write erase command currently preserves the IP
address if the configuration was set to a static address.

© 2006 Cisco Systems, Inc. All rights reserved.

CWLF v1.0—m5-5

The figure illustrates how to download new configuration files to the access point. Distributing
a system image file via the radio interface is not supported.
You can also erase the configuration file and revert to the default settings of the bridge. The
mode switch can also be used to set the access point to factory defaults.
Note

5-116

The write erase command currently preserves the IP address if the configuration is set to a
static address.
