Foundry Configuration Guide for the FESX, FSX, and FWSX
23 - 2 © Foundry Networks, Inc. December 2005
Only one flash device is active at a time. By default, the primary image will become active upon reload.
You can update the software contained on a flash module using TFTP to copy the update image from a TFTP
server onto the flash module. In addition, you can copy software images and configuration files from a flash
module to a TFTP server.
NOTE: Foundry devices are TFTP clients but not TFTP servers. You must perform the TFTP transaction from
the Foundry device. You cannot “put” a file onto the Foundry device using the interface of your TFTP server.
NOTE: If you are attempting to transfer a file using TFTP but have received an error message, see “Diagnostic
Error Codes and Remedies for TFTP Transfers” on page 23-13.
Determining the Software Versions Installed and Running on a Device
Use the following methods to display the software versions running on the device and the versions installed in
flash memory.
Determining the Flash Image Version Running on the Device
To determine the flash image version running on a device, enter the show version command at any level of the
CLI. Some examples are shown below.
FESX, and FWSX Devices
To determine the flash image version running on a FESX, or FWSX device, enter the show version command at
any level of the CLI. The following shows an example output.
The version information is shown in bold type in this example.
• “03.0.00T53” indicates the flash code version number. The “T53” is used by Foundry for record keeping.
• “labeled as FER03000” indicates the flash code image label. The label indicates the image type and version
and is especially useful if you change the image file name.
• “Primary fer03000.bin” indicates the flash code image file name that was loaded.
